2000 Firebird blows oil past oil filter gasket

Showing 7 out of 7 Posts
Question From ghenry on 2000 Firebird blows oil past oil filter gasket

My sister has a 2000 Firebird,3.8 V6, 200k miles. Oil was changed a month ago. It is swelling the oil filter, then blowing oil past the seal at a high volume. I checked to make sure it was the right filter, replaced the filter and oil, and got the same result. What could cause this?

Response From Loren Champlain Sr

As Tom suggested, remove the oil filter and check to make sure the gasket from the old filter isn't there. I've only seen it once, where the check valve in the oil pump went bad and allowed that much oil pressure to 'expand' the filter. Connect an oil pressure guage to check actual oil pressure. Don't rely on the dash guage.

Response From ghenry

Thanks for all the replies. I've never seen this before either, but should have remembered the check valve. I did check to see if the old gasket had stuck to the mount, then replaced the filter and refilled it with oil. After we started the car it took about 30 seconds for the bottom of the filter to expand and start spewing oil everywhere. I'm going back over Saturday to look at it again. If I can't figure it out I'll let you know. Again, I really appreciate the help. If I can be of assisstance to any of you, feel free to message me. I've been working on Chevys for a little over 20 yrs. I may be able to lend a hand. Lotsa love and God bless.

Response From Tom Greenleaf

ghenry:

Feel free to browse around and share your know how on any thread you wish. It's not restricted to just regulars or old timers here at all.

With your excessive oil pressure seemingly for real that pressure valve must be the issue. Loren said he's only seen one and I've never seen that as said to the point that I wasn't the least bit sure where they put that device. If like I recall back in the stone ages* of tech school the principle action is like that of a radiator cap pushing against a spring so there isn't much to allow over the pressure and breakage should cause no or very low pressure.

Stone age man....*

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Other than a freak failure I could only guess this could (highly unlikely) happen to a totally sludged out engine - but in 10,000 years the sludge I've noted was more on return (passive dripping back to pan) side of oil issues.

Do report what you actually find this fault to be as I'm curious if not many who could search out this issue,

T

Response From Loren Champlain Sr

Tom; The oil pressure relief valve is in the oil pump, itself.. I've run into quite a few over the years that would cause high oil pressure, but only one that I can think of that would 'blow up' the filter. I'm hesitant, though, to recommend replacing the oil pump without further diagnostics.

Response From nickwarner

your system should have a relief valve in it, and it has stuck completely or partially shut. Does your gauge max out when this is happening? Not sure exactly where to look on this motor for the relief valve, but that can do it to you.

Response From Tom Greenleaf Top Rated Answer

There should be a pressure relief that as long as I've seen (loooooong time not one has failed!) which also allows oil to bypass a plugged filter or if volume exceeds supply oil passes the filter in part as to not deny engine of needed oil more important than filtered oil.

The bloating of a filter is shocking if really so! Never, never saw that! Are you sure? What can and does happen is and old filter gasket is stuck to the engine side such that you have two and can work for a short while but will leak like nuts at some point, hopefully right away so you catch the mistake.

The pressure relief is TMK like a spring loaded ball. I can't think of how it could allow pressure exceeding that spring?? At a loss with what I see here. Need help if not just two gaskets there by mistake or engine damage may result!

1993 Chevy 1500 w/ 5.7 liter oil filter housing leak

Showing 2 out of 6 Posts | Show 4 Hidden Posts
Question From mrcurti on 1993 Chevy 1500 w/ 5.7 liter oil filter housing leak

I have a serious oil leak that appears to be coming from above the oil filter housing. I don't see an apparent way to remove it, but also have not removed the oil filter either. Also once removed, how hard will the repair be? Can any one help?

Response From sbake58

Does it have the remote filter with oil lines attached to the housing on the engine? If so, there is a gasket between the housing and block which can harden and leak. If it's the standard mount, there are two bolts attaching it to the block which can loosen and allow it to leak in the same manner.

Response From pjstanley Top Rated Answer

There is a gasket where the oil filter attaches. My 96 GMC had the same problem. We thought it was the front main leaking. It poured oil. We had the front main completely redone. While fixing the front main, the oil filter gasket was noticed and replaced. It turned out to not be the front main. The gasket was replaced and no oil leak since.

Response From shads

I had the same problem a few years ago with my '93 Chevy. There are a couple of gaskets on the mating surfaces of the housing. When I replaced the gaskets on mine, the old ones crumbled in my hands. I guess with all the heat and oil exsposure over the years. If I remember correctly there are two bolts that hold the housing in place, remove the bolts, pull off the housing, clean off the old gasket material, replace the gaskets and reinstall with a new oil filter. I would not recommend using gasket maker, get the real gaskets. Mine hasn't leaked since. Pretty easy but messy job to do.

Response From fatcat128

Try taking off the filter and tightning the bolts inside of the "housing" might not work but it is worth a try.

Response From tomsmith

i've never heard of an oil filter housing. but from what you've said, you might want to take off the oil filter and see if it is double gasketed(left the old O-ring on there from the last time the filter was changed.) it happens more than one would think, i used to work at an instant oil change place, and would see 5 or 6 a week. also, when you change the filter, lightly coat the O-ring with fresh oil. might also want to check and see if your valve covers are leaking.

Question From boogettyman on morning engine rapping noise

HELLO,
I TOOK MY CAR FOR AN OIL CHANGE AND WHEN THEY WERE FINISHED I PAID AND GOT IN MY VEHICLE AND LEFT , I WENT APPROX. 250 FEET DOWN THE ROAD AND MY OIL LIGHT CAME ON SO I TURNED AROUND IMMEDIATELY AND WENT RIGHT BACK AND TOLD THEM . THEY TOOK A LOOK OIL WAS ALL OVER THE UNDERNEATH OF THE CAR - WHICH IS A 2011 NISSAN MURANO - THEY CHECKED IT OUT AND SAID THAT THE OIL FILTER GASKET HAD A CRACK AND THAT'S WHY THE OIL LEAK - THEY CHANGED THE FILTER AND SAID THEY REPLACED ABOUT 2 1/2 QUARTS OF OIL . I THEN LEFT AND THINGS SEEMED TO BE OK - UNTIL NEXT MORNING WHEN I STARTED THE CAR AND HEARD A DRY RAPPING NOISE THAT LASTED ABOUT 4-5 SEC. - I TOOK IT TO THE NISSAN DEALER AND EXPLAINED EVERYTHING TO THEM - THEY DID A OIL CHANGE AGAIN AND PUT THEIR OIL & FILTER IN IT AND THOUGHT THAT IT MIGHT TAKE CARE OF IT .. NEXT DAY - SAME THING - SAME NOISE AND EVERY MORNING SINCE ... HAPPENS WHEN THE CAR SITS ALL NIGHT . CAN SOMEONE EXPLAIN WHAT KIND OF DAMAGE WOULD OCCUR WHEN YOU LOSE YOUR OIL LIKE THAT ... AND WHAT WOULD BE THE FIX TO THIS SITUATION !!!!! I FEEL THAT IT HAS DAMAGED SOMETHING INTERNAL WHERE AS THE OIL DOES NOT STAY RETAINED IN THE UPPER END OF THE ENGINE . SO IT MAKES THE NOISE WHEN I START IT UNTIL OIL GETS PUMPED TO THE UPPER END .?????? THANK- YOU FOR YOUR HELP....!

Response From Hammer Time Top Rated Answer

That oil change place owes you an engine and you need to stop messing with the car and notify them immediately that you want the engine replaced and by someone other than them. What happened is when the guy put the oil filter on, the old gasket was still there because it didn't come off with the filter and when you double gasket, they pour oil out and do severe damage. They also lied about how much oil they put back in because that car was empty when you brought it back to them. They have insurance for things like this but don't waste any more time.

2006 chevy cobalt erractic idle

Showing 2 out of 7 Posts | Show 5 Hidden Posts
Question From Clayton1000 on 2006 chevy cobalt erractic idle

Hello. I have a 2006 Chevrolet cobalt, engine 2.2, mileage 110,000. My cars idle fluctuates and sometimes stalls.
This problem has started about 6 months ago and has gradually gotten worse. There has been no trouble codes from the computer. When I press on the gas the car hesitates for a moment and the runs great. I have the Haynes repair manual which which suggests checking the PCV system. It's instructions lacks clarity so here i am asking for help on this forum.

Following the books instructions i removed the PCV hose and checked for a vacuum? Which port? On the engine port or the air intake system port? I put a vacuum gauge to the engine port and I got a very slow pulsating pressure increase which is normal to me as blow by past the piston rings. If there is supposed to be a vacuum at the engine port (in the crankcase?) as the book implied, where is this vacuum coming from? I did not finish this test and will later check to see I have a vacuum at the air intake system port which I think would be normal.

Nothing that has been done to this car has shown an improvement. Here is what has been done in the last couple days. The MAP sensor has been replaced from a junkyard. The MAF sensor has been removed and cleaned twice with a spray can of MAF cleaner. I sprayed the throttle body with a spray can of carburetor and choke cleaner. Here is what has been done in the last 6 months. A new air filter, fuel filter, and spark plugs. If I hit the problem will I see an immediate improvement? Does the computer need to be cleared by disconnecting the battery?

Any suggestions to help me solve this erratic idle problem will be greatly appreciated.

Response From Discretesignals

You should take it to a shop that can access datastream information. Looking at datastream information might give some clues as to what is going on. They could also smoke check the engine for vacuum leaks that you may not see using conventional methods.

Response From Clayton1000

Thank you for responding!

As I went to complete the testing for the PCV system I noticed that the air intake had oil inside. The engine was sucking oil into the air intake through the PCV hose. I checked the engine oil level and the oil level was above the max mark on the dipstick. The car was taken to a garage that does nothing but change the oil. The car was almost due for an oil change. They said that this engine takes 5 QTS of oil and put 5 QTS of oil in the engine. After the oil change I checked the book and they were right, this engine takes 5 QTS. I checked the dipstick over and over again and the oil level was above the max mark on the dipstick. The next day I drained just over a QT of oil out of the engine putting the oil level on the dipstick ¾ of the way full. I wiped the oil out of the air intake. I took a toothbrush and carburetor cleaner and cleaned OIL out of the throttle body. The car now idles perfectly.

Take care Clayton

Response From Hammer Time

This engine takes 5 quarts with the filter. Running it low will do harm to the engine.

Response From Tom Greenleaf Top Rated Answer

Clayton - some questions, thoughts about this: I can't think of anything more important to an engine than proper oil, oil pressure and level. It is TOTALLY worth paying attention to and always was. Changing it on manufacturer's schedule listed in car's manual OR many will suggest 3 months or 3,000 miles whichever comes first.

Seems everyone is pretty sure that 5 quarts with filter is the proper amount.

I'm still concerned that you found oil in the intake. To me that's a terrible sign and worth total investigation as to why. Many PCV systems operate on the same basic ideas for decades on end now. Some blow by is going to happen such that all that fumes in crankcase sealed areas are polluted air with oil mist frequently in it so the idea is to burn that off in a metered manner that a PCV valve does using manifold vacuum. It also should separate out oil mist as a system and pick up filtered air in some manner to replace the vapor removed done in assorted ways but to achieve the same goal.

When/if blow by exceeds what the PCV system is burning off you can get pressure instead of slight vacuum in crankcase sealed areas that are all thru up to the valve cover(s) and any remote oil fill caps and so on. When pressure is there either clogged PCV hose to it or however done many can send the mist backwards ending up in a puddle that you did just spill there.

It's not my place in this world to bash the oil change only places but they haven't had the best history at least local to me when the idea became popular and no argument it's handy for customer's.

The scare is some are advertising how fast they can change oil down to a 10 minute guarantee! WHAT! Have come to find out they are sucking oil out thru dipstick tubes not even touching a drain plug! Now I'm more scared and can't believe that gets all of it or dependable vehicle by vehicle types. Marine engines using automotive type engines did plan on that - different reasons and not this issue.

There's a chance of getting the wrong dipstick IMO with this rat race oil changing. Drain plugs stripped, caps left off. Wrong fluids put in topping things off, leaving an oil filter gasket stuck on engine from old one and the list goes on.

Can you change your own oil at least once letting it drain for a good while, filter too, measure and know you have the exact amount, run engine to circulate then let it sit level for at least 15 minutes and see if it's on the right mark?

I've done that to all (100s over the years) of my own assorted vehicles all used and found many wrong to WAY wrong! Would even purposely only fill to read one quart low and see if that mark is right too. You can't do that in quick change places - no time for it. That was also to check if ones with an oil level warning system really warned you if you were really ONE quart low. Most don't! Has to be more than one quart too low if they work so I don't trust that bull on new or older vehicles.

One more and enough of this novel - sorry. The dipstick is also a seal for the crankcase.

The subject is too important to ignore. Too many perfectly good engines have been destroyed by things going wrong,

T

Response From Clayton1000

Thank you all for responding!


Even though I stated earlier that this car is MY car, its not really and I was not the one who regularly checked the fluids. With that being said, I have no comparisons as to whether or not there was an issue with the oil level right after an oil change in the past.

This car has had regular oil changes (every 3000 miles) at the same oil change business. I am suspicious that their oil regulator that they set to 5 qt s may be faulty or the guy in the pit did not let all the old oil drain out and I had not returned there to inform them about this issue. I would suspect that they would have been aware this by now if this has been an ongoing problem for 6 months.

I have continued to check the oil and the oil level is still at 2/3 up to the full mark on the dipstick. When it comes to a choice between the book specification or the dipstick I can't ignore the dipstick. This car was purchased 2nd hand with very low mileage and the previous owner was a car rental business. With this having been said I'm finding it hard to believe that this car has the wrong dipstick. The car has continued to idle perfectly and no oil in the air intake. I have not found a reason to believe that engine coolant is ending up in the oil pan.


The next oil change will be done at home so we can see if there is a problem with the oil capacity.


Here's something interesting to consider!


When I took the car to the oil change place I told them that I'm troubleshooting a rough idle problem and their reply was we see a lot of that with this model.
I was told by employee at an automobile auction that every Chevy Cobalt that passed through there had a rough idle problem.


Take care Clayton

Response From Tom Greenleaf

Quote ">>I was told by employee at an automobile auction that every Chevy Cobalt that passed through there had a rough idle problem. "

Perhaps the have a propensity was told by employee at an automobile auction that every Chevy Cobalt that passed through there had a rough idle problem. Is this to say they make the same mistakes over and over or are better trained at excuses?

Agreed, the dipsticks are the way to go to be sure but know it's the right dipstick.

BTW - if coolant was getting into oil it would froth up like a milk shake. Fuel can get into oil and make it so thin and too full you get cylinder wash/wear and destroy an engine.

If they have faulty equipment and are not checking it's negligence on their part. Makes you wonder if they are motivated to care,

T
