Buick Regal Custom 1994, 100,000 miles

Showing 2 out of 2 Posts
Question From ab01 on Buick Regal Custom 1994, 100,000 miles

Hi,Happy New Year, Im new on this forum..I bought a Buick Regal Custom 1994 with 100,000 miles a couple weeks ago. That car was stop for long period and had to many problems. I fixed most of them and run the unit without any engine problems. The unit had a oil leak from the valve cover gasket and I decide to repair. After that repair, the unit began to present starting problems,runs about 2 or 3 minutes, after that, the motor began to trembling and shut off. I took off again a couple times all the parts that I have to take out to remove the gasket and see whats wrong but everything looks ok. Can anybody help me on that?
Thanks.
Ab01

Response From Discretesignals Top Rated Answer

Does the unit restart right after it stalls out? You may need to use a fuel pressure gauge and check the unit's fuel pressure while the unit is having the issue. This would give you some direction on diagnosing the unit's problem.

Question From shadowzero26 on I need to clean or replace something under this thing

93 Buick Park Avenue 3.8 V6 130K miles

Please, what is this called and what is under it that I need to replace/clean/stop the oil from leaking out from it?

Response From shadowzero26



Sorry, I didn't understand the markup.

Response From Discretesignals

That is a valve cover, rocker cover, or cylinder head cover. Underneath is the valve train.



Usually what leaks are the gaskets that seal the rocker cover to the cylinder head. You have to remove the cover and replace the gaskets. It is also a good idea to replace the bolts' rubber grommets. If that one is leaking, the valve cover on the back side of the engine is probably leaking too.

Response From shadowzero26

Thank you very much for the information. I will print this out and do it right away. The backside valve cover is going to be tough to get to.

Response From Tom Greenleaf

Smile - someone has been there before with that color. Alone not hurting anything but off you could clean it real well and paint it black if it bugs you,

T

Response From Hammer Time

I don't believe that cover is really that color. It looks like it was highlighted on some imaging software.

Response From shadowzero26

Yes, I did highlight it with the computer.

Response From Tom Greenleaf

That's cool. Wish I could do that with pics. No matter it's a valve cover. If leaking itself and not spilled oil they come as a whole set. Yes some nuts + bolts will be hard to get at and or stuff out of the way. It's shocking how many tools "we" accumulate to get at stuff.

Whatever, if you do take this on do check that it in good shape and not cracked anywhere. Tighten to specs not like it's holding the whole car together or things will go wrong,

T

Response From shadowzero26 Top Rated Answer

Sorry about the super long wait, but it wasn't the only thing wrong here. What I actually had to have done was replace both the front and the rear valve cover gaskets, the trans lines, and there is also some antifreeze leak somewhere, but I don't know where... So long story short, I finally fixed most of the problems, but it definitely needed new gaskets and trans lines. It drives smoothly and smells decent once again!

'98 Buick Regal bad Intake Manifold Gasket

Showing 2 out of 23 Posts | Show 21 Hidden Posts
Question From terryhop on '98 Buick Regal bad Intake Manifold Gasket

I have a 1998 Buick Regal GS, supercharged, with the 3.8L V6 engine and 150k. The intake manifold gasket(s) is/are bad and I'm wondering if a relative novice (myself) can realistically tackle this project with the proper tools. I also have a cracked radiator and would like to do the work myself if possible and save a good bit of money in the process. The car is obviously not of great value at this stage of the game.

Thanks for the advice

Response From PatrickH Top Rated Answer

Doing this project can be a real pain. Just be ready to buy a few gaskets and if you can, replace anything that may need replacing in the next couple years while you are there and have the good access.
I just attempted this project this week and these is what I decided to do while I had the car apart
Oil change, Fuel filter replaced, New rechargeable air filter, Intake manifold gasket, Rear valve cover gasket, Thermostat, Spark plugs and new wires, Coolant flush, Fuel injector O'rings, Throttle body gasket, Plenum gasket, Super Charger Fluid topped off
Front valve cover gasket was replaced by dealership with a factory recall
Be very carefully with the injectors. As you can see in this picture, the plastic washer tip type things are very hard and crack like a stale cracker.. You can NOT buy new plastic washer, you will have to buy a new injector if you break this. Or there is a injector ring of another style for another car that may be used and it seems to work for me so far. I will get into that later if anyone is interested.

You don't need to disconnect the fuel lines, just un bolt the fuel rails and use a bungee cord to hold it above the motor, then you can carefully pull out the supercharger and manifold out from underneath it, threw the left side. just remember to unplug everything as much as you can so you can raise it up enough. Don't put too much tension on the wires, just enough to raise it up out of the way.

Only disconnect what needs to be disconnected.

Intake Manifold 18ft lbs (dealership told me this)

Also you will need to drain the radiator. before replacing the intake manifold, be sure to use about a quart of oil to wash all the water down back into the oil pan. You will see the coolant and know what I'm talking about at this point.
Be sure to do a oil change before starting your car when finished.

Pictures below



Response From PatrickH

Now I have a question

Attachment below.
The two little gasket strips you see in the picture below, the Orange with the Black tab on the side.
Which way do these go on?
The Black tab on the outside or the inside?
They will go on both ways, but only one way is correct.

Response From Hammer Time

Those are not factory gaskets. They should have come with instructions. The factory gaskets don't have that difference.

Response From PatrickH


Those are not factory gaskets. They should have come with instructions. The factory gaskets don't have that difference.

Felpro / Intake Manifold Gasket
Part Number:
MS95977-1


Only instructions was to put the little dabs of silicone in the corners..

Response From Hammer Time

Wow, I've never seen those colors on a Fel Pro gasket. From the picture it looks like the side rail might be longer on one side than the other. I suspect it will only fit good one way.

Response From PatrickH

Well when I was putting it on the car, the gaskets fit both ways.. That's the problem.
The way I installed seemed to me the best fit and made more sense then the other way.
So I torqued it to 18ft lb (by hand just a good tight snug) inner to outer and checked them all 3 times.
after getting my car back together I did a coolant flush, after running in my driveway for a couple hours off and on, there was no leaks. I took it for a test drive on the freeway and can smell coolant.. I pulled over and look and it was leaking and steaming from the left side.. Right side looked a little wet, but you can see coolant on the left side pretty well.. When I looked at a picture online, I seen that the black tab was on the outside, but I don't have any details on that image, so it could have still been the wrong way..

Also, since I only drove about 5 miles on these new gaskets I replaced, you think it's safe to reuse them when I tear it down again to fix this issue?

Here below is the image I found online, this is the way I installed them on my car.

Response From Hammer Time

Those are end gaskets anyway. they don't seal coolant. they seal oil from the vally and i'm sure if they didn't specify, it's probably not important. It's the side gaskets that you messed up.

Response From PatrickH

I just went out and started my car again to see if I can see anything this time before pulling it back into my garage.
I found the leak.. It's the hard plastic water pump elbow thing that connects into the intake manifold, that's where it's leaking from
Hopefully I can just remove the pump easier then taking off the whole top of the motor apart again.
Not sure why it wasn't leaking while idle in my driveway last night, probably the coolant wasn't fully cycled threw the engine yet and it wasn't at a high enough level to pour out that spot?
leaked with 30 seconds this time..
I don't think I remember seeing much of a O'ring at that spot and thought that was kinda strange, but for future reference to anyone who does this job, watch for this before installing the intake back on..

Pictured below

Response From Hammer Time

You don't pull the manifold for that but you will have to remove the belt tensioner. Be sure to check for pieces still in the hole. those thing break off clean right at the O-ring and leave the piece inside.

Response From PatrickH

ok, thank you.

Response From Hammer Time

There are a couple O-rings on the tensioner that you should change at the same time. Be carefull not to break it getting the metal part out of the block. It's an expensive tensioner.

Response From PatrickH

I removed the alternator, the pulley wheel and 2 15mm bolt and was able to pry it back just enough to pop out the elbow bypass deal. Might have to do a little more to get it back on since the new part will have a added inch.
The only O'rings I see are on each end of the elbow piece. And they where stuck inside along with 1/4" of plastic on each end..
I wish I noticed this before putting the manifold back on, but I guess I just wasn't expecting to find a issue like this and wasn't paying close enough attention. Lesson learned

Here's a image of what I pulled out.. Took about 10 mins
The other small broken piece is still stuck inside, just haven't took it out yet for the picture

Response From Hammer Time

Yes, the is one broken piece missing from that picture.

Once you remove the bolts that hold the tensioner on, there is one metal part of it at the bottom that slides into a hole in the block with an O-ring. That's the part I'm referring to.

Response From PatrickH

Do you know the size of the O'ring that will need to be replaced or a Part Number by chance?
I'm sure the dealership may be able to figure it out for me, but just encase they can't

Part number for the coolant bypass tube for local auto stores is Part Number# 47065 (or) GM part Number# 24503423

Since I found the numbers, I see now that it's a stocked part at the part stores.
When I called my local parts stores, no one could figure out what the part was I was talking about..
Doing a category search I could not find these parts either.

Response From Hammer Time

Can't help you on the O-ring. You either going to have to match it up from a set or get it from the dealer.

Response From PatrickH

Got back from the dealership
There is two O'rings I was sold.
One of them is larger then the other, so the one that cost more I'm assuming is the bigger one.

O'ring part numbers
Part# 25537068 = $1.50
Part# 24502846 = $3.00

Response From Loren Champlain Sr

terryhop; The Mitchell guide calls for 3.5hrs labor, so it shouldn't be too tough. I'd recommend flushing the cooling system very thoroughly before you get started if you can do so without letting it overheat. When you are done, use normal, green, ethlyn glycol anti-freeze rather than the Dex-Cool that more than likely caused this problem.

Response From Hammer Time

the Dex-Cool that more than likely caused this problem.

Don't be spreading untrue rumors now................

Response From Loren Champlain Sr

LOL...I KNEW that I'd hear from someone on that. Can you spell class action suit? I wouldn't put that stuff in my lawnmower. Oh, boy....Now I've done it!

Response From Hammer Time

Even the so called suit has nothing to do with gaskets. The gaskets are just plain bad and will fail with any coolant.

Response From re-tired

The one variable we don't know is your mechanical abilities and how bad you REALLY want to do this . For a qualifiied tech this is a straight forward job. For a novice with the proper tools and a good manual and the ability to understand the terms and procdures it is a doable project. IMO

Response From way2old

I agree with re-tired. Set aside a weekend and a 12 pack(minimum) and have a good manual to assist you with the technical aspects. Go for it. Number and mark where the pushrods come from. Place them back in the same hole.

2006 Buick Engine Seal repair

Showing 2 out of 2 Posts
Question From Gabriell on 2006 Buick Engine Seal repair

2006, Buick Lucerne CXS, 4.6 Liter Northstar V8, and 96,000 miles.

I believe that I am in the correct section of the forum. If I am not, please let me know where I should post this.

I have had the same/similar repair done several times at a repair facility. At 71,962 miles, they found an oil leak from the oil pan, valve cover and front crank seal. They replaced the Valve Cover Gasket, cover and seals.


At 90,085 miles, they again found an oil leak from the oil pan, valve cover, rear main seal, and power steering gear. They replaced the power steering rack and resealed the valve covers and oil pan.

At 95,381 miles, they found an oil leak from the front and read valve gasket and found both valve cover gaskets leaking, and they replaced both the left and right.

I have researched, and I have not found this to be a consistent problem with this engine/vehicle/year etc. Are the repairs being done incorrectly/negligently, is there something else that I should have done?
Thank you for your assistance.
Gabriell

Response From Tom Greenleaf Top Rated Answer

Gabriell:
If this is common to this exact engine, model and year there should be a TSB (Technical Service Bulletin) on this. I suggest you take the complaints you may find out on the web with a grain of salt to some degree. People just don't bother when a vehicle exceeds all expectations to brag but will for complaints.


I haven't heard of this at this site to this degree at all and or most any with repeated same issues. Unfamiliar with this as a problem because of that.


Now the questions and opinions on my part: Have you owned this from new or a good history from new? You've marked the miles to the miles when things were done.


Are you getting or doing the routine service on this as per recommendations for it? Specifically type of oil exactly and on time and miles? Most vehicles will fall into what I'll call a "severe" duty schedule which about doubles the frequency of things like oil changes suggested.


All the gaskets you mentioned are stressed when crankcase pressure which really should still be a slight vacuum are excessive IMO and experience with about any piston engine frequently plain wear and blow by.


I'll wait with you what others here have to say on this engine for these type issues with oil leaking. Rack and pinion isn't really engine so that's separate.


Couple more thoughts. Some engines do in fact have propensity to leak and frequently the gasket makers specifically Felpro has made upgraded gasket material for many. If this work was dealer done there's some pressure to use only factory parts that if known to do this and not upgraded might still be used.


If (IDK on this) engine was trying out new metals for specifically pistons and engine cylinder metals (some in history have done that) it didn't work out.


Back to repeats of these type issues: To me it means a worn engine! It is too early for any that are not abused or a poor design. I don't know exactly how mechanic error for this could be the problem unless you know you used the same mechanic/tech and something is being done incorrectly.


Bet you've spent a lot of $$ on these repairs already. I suggest for now spend a bit more for a general engine diagnostic for plain wear to see if that comes up as the cause as it smacks of just that,

Oil Leak 1999 Buick LaSabre

Showing 2 out of 3 Posts | Show 1 Hidden Posts
Question From TGMcCallie on Oil Leak 1999 Buick LaSabre

A very small amount of oil (looks like motor oil) is leaking out from under the front end of my automobile. I can't exactly tell where it is coming from.

A friend of mine across the street told me that he got a quart of Lucas Oil Stop and put in his car and it stopped his oil leak. Has anyone had any experience with this type thing? I have read about it somewhere and I think that it said this compound caused your seals etc to swell (sort of Viagara for the auto I guess). If this is the case will this cause other seals in your engine to go bad?

Thanks

I am afraid I have no experience with the product you mentioned as far as leak stopping capability or the effect it will have on your engine. I do however have a customer who uses lucas oil in their truck and will not use anything else. I also am very familiar with your vehicle and the source of the oil leaks and the 3.8 engine has the typical oil pan leaks that are not to difficult to repair. Other engines are more inclined to have intake issues and you alos may wish to examine the valve cover gaskets they too have noticable leaks.
The key is to purchase some oil leak dye, introduce this into your crankcase and then drive for a few days and using a black light insoect for the source of your leak. I cna not recommend the cleaning of your engine as that is not enviornmentally acceptable noe, but it can help to locate a leak by removing old grime grit and oil.
I would recommend locating the source of your leak and repairing that leak versus turning to an alternative leak stop.

Thanks for the info. I personally agree with you. If a product will swell a seal, looks like it will effect it's purpose somewhat.
