Water in Cylinder

Showing 6 out of 7 Posts | Show 1 Hidden Posts
Question From Sabot15 on Water in Cylinder

I have a 96 Oldsmobile cutlass supreme with 92k and the 3.1L V6.

It recently developed a miss on cylinder #1. I have a small amount of coolant in my oil and some sludge in my radiator. I assumed it was the the very common lower intake manifold gasket failure that was causing the problem, but I noticed something weird.

When I removed the spark plug on #1, and I turned over the engine, antifreeze shot out.

When I look at the way the manifold fits, I don't see any way that water could get directly from the jacket journal to the intake journal. I am assuming then, that this MUST be a head gasket failure. Is that correct?

Thanks!

Response From Hammer Time

The intake gasket can't put coolant into the cylinders in this particular engine. You're looking at a likely blown head gasket.

Response From Sabot15

Yeah, that's what I thought. I went ahead and tore it all down... when I got the head off, I saw dark spots in the cylinder wall. I think water sat on it for awhile. It feels slightly rough there.

Does this mean I need to pull the block and have it machined?

Here's a picture:

Response From Hammer Time Top Rated Answer

No, I'd say you're looking for a new motor. You may even have a cracked block but either way the damage to that cylinder wall makes it not worth fixing.

Response From Sabot15

Well, not the news I wanted to hear, but thanks for the advice.

Response From Tom Greenleaf

It's bad news as Hammer said for this engine. Bad enough for the flaws you can't see and when you can see and feel them it's over IMO for that block which to me means the engine.


Now time to find the right and reputable salvage place if you want to keep this longer for a fully checked out perfectly matching used and whole engine - best ones will have results of testing it out right on it printed out. I'm getting old for this crap but when this would happen I would be the sucker to go check engines some on a pallet, some still in a vehicle that was salvaged for another reason totally, best if the problem was in the rear or side IMO. Batting 1,000 on that so far,

Response From Tom Greenleaf

Antifreeze shot out of a cylinder - certainly not good. You'll know more exactly when taken apart and parts sent out or pressure into that cylinder when at TDC now and see where it goes as best you can,

2001 Monte Carlo intake explosion

Showing 2 out of 7 Posts | Show 5 Hidden Posts
Question From Matt98svt on 2001 Monte Carlo intake explosion

Hi all, I have a 2001 Monte carlo ss with 90k miles and no mods. I was in the process of changing a window regulator and ran down my battery to the point of needing to jump start the car. I try to crank it 3-4 times with the jumper cables on and it doesn't have enough juice to turn over till about the 4th try..and when it just starts to turn over there is a loud BANG! I jump out and there is a small fire limited to about a 3 inch radius and about a foot high so I grab the fire extinguisher off the nearby wall and spray down the engine. After inspecting the damage it appears the plastic upper intake exploded into a million pieces. I was surprised how thin the plastic that makes up the intake was. The only other damage I see is one of the injectors (back of engine closest to passengers side) is pushed out of the lower intake about a half an inch and the fuel rail that connects to it is bent slightly. This is where the fire was and the injector looks shot...other than that there is no fire damage. Of course spraying the fire extinguisher sprayed this fine sand like stuff all over and into the engine. I had it towed to a shop and they are supposed to look at it Monday. My plan was to pull the lower manifold and clean out as much of that extinguisher mess and plastic. I wanted to do a leak down on that back cylinder and maybe put a borescope in the plug hole but I really don't feel there is any internal damage...but not certain. The intake is only like 1/16th in thick plastic which was the path of least resistance and it exploded before the engine ever really started
turning over. Not sure why this happened but found other instances online of gm 3800 series II engines having the same intake explosion. I had changed the plugs and wired about two weeks ago and the pvc valve and had no issues such as misfires or anything after that so not sure if that could be related. Any advice on getting this fixed is appreciated and I will post pics soon

Intakes explode because fuel builds up inside and then a source of ignition like a backfire ignites it. You need to determine if you have a fuel leak from something like a stuck open injector or an ignition problem causing the backfire.

The thickness of the intake isn't important because there is never supposed to be any pressure in there anyway.

Response From Matt98svt

The mechanic called and left a voicemail that he only glanced under the hood but that he recommended replacing the upper intake the fuel rail and all 6 injectors....(quoted $1000 for the 6 injectors alone)$2200 total. He said if it was him though he would replace the entire engine since the fine sand like stuff from the extinguisher prob got into the engine. The motor wasn't running when I sprayed it though and I was 10ft away so not sure I need a new engine here.

Response From Tom Greenleaf

#1 - Glad you had an extinguisher around!


Fortunately I don't have but ONE time I had to use one and was just a fine baby powder dusty crap but worked thank you. IDK if this is worth tossing total engine quite yet? Think I'd just blow the crap out of cylinders with compressed air and think/bet you'd be OK but mind you I'm not there looking at this show either.


Small point was that dust from the extinguisher made a simple, no damage to anything fire on engine seriously not want to fire after the fact not what caused the fire - carb cleaner a bit too much in that case on a hot spot on manifold.


End of that story is it didn't hurt anything once cleaned up mostly with compressed air externally as it was ugly of course,

I personally don't think the engine is going to need to be replaced. That is a little extreme.

I'm sure the engine wasn't running when you blew powder all over it, so no big deal.

Response From Hammer Time

I agree, you need a manifold and to repair whatever caused the explosion in the first place. Make sure none of the plastic went into any of the cylinders.

You know it is funny that GM had a recall on 2000 Monte for the fuel pressure regulator leaking and causing intake manifold explosions in 2004.

THIS BULLETIN REPLACES 03054A ISSUED FEBRUARY 2004, AND IS BEING REVISED TO INCLUDE 1998-2000 BUICK LESABRE, PONTIAC BONNEVILLE; 1998-99 OLDSMOBILE EIGHTY-EIGHT; AND 2000 BUICK PARK AVENUE, CHEVROLET MONTE CARLO AND IMPALA MODEL YEAR VEHICLES. DUE TO PARTS AVAILABILITY, 03054B IS BEING CONDUCTED IN 2 PHASES. PHASE 1 WILL CONSIST OF 1998-1999 BUICK LESABRE, PONTIAC BONNEVILLE AND OLDSMOBILE EIGHTY-EIGHT MODEL YEAR VEHICLES. PHASE 2 WILL CONSIST OF 2000 BUICK PARK AVENUE AND LESABRE, PONTIAC BONNEVILLE, CHEVROLET MONTE CARLO AND IMPALA MODEL YEAR VEHICLES. WHEN SUFFICIENT PARTS ARE AVAILABLE TO NOTIFY CUSTOMERS OF 2000 MODEL YEAR VEHICLES, YOU WILL BE NOTIFIED AND WILL RECEIVE A NEW INITIATION REPORT. PLEASE DISCARD SAFETY RECALL BULLETIN NUMBER 03054.

CONDITION

General Motors has decided that a detect, which relates to motor vehicle safety, exists in certain 1998-2000 Buick Park Avenue, LeSabre, Pontiac Bonneville; 1998-99 Oldsmobile Eighty-Eight: and 2000 Chevrolet Monte Carlo, Impala model year vehicles equipped with a 3.8L V6 (RPO L36 - VIN Code K) engine. These vehicles have a much higher than usual rate of fuel pressure regulator diaphragm leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. In low battery conditions, if the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire. The backfire can rupture the intake manifold, causing a loud bang. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak. If there is an ignition source, a fire can result.

Slow engine cranking and difficulty starting the engine could indicate a low battery. Poor driveability or a check engine light could indicate a fuel pressure regulator leak.

CORRECTION

Dealers are to inspect the engine fuel rail and, if necessary, replace the fuel pressure regulator.

2001 Olds Alero, mystery oil light

Question From DanDude7000 on 2001 Olds Alero, mystery oil light

Hey Guys,

2001 Oldsmobile Alero V6 coupe, 100k miles.

Last night I was driving back from a restaurant that is just a couple blocks from my house. Just before I got home the red oil warning lamp lit up (the oil-can one, not the 'low oil' one). The car was running fine and did not seem to be overheating. I pulled into my driveway and shut it off. I last changed the oil (lube shop) just about 3k miles ago.

This morning I checked the oil- the level is fine, light/medium brown. I started it up- no warning light. I drove around the block- no warning light or signs of overheating.

I don't know what to do at this point. Everything seems to be fine now, but I'm scared to drive it knowing that whatever caused the prior warning didn't magically fix itself. Could it have been a temporarily clogged oil filter? Faulty warning sensor?

I should mention, about 10k miles ago it was leaking coolant- ended up having the intake manifold gasket replaced. Haven't had any troubles since.

Thanks in advance for your help!

Response From Hammer Time

That is a very serious warning light. It indicates insufficient oil pressure to operate the engine and it shouldn't be driven that way at all. It could be a faulty sensor but the best way to find out is to just replace it.

Response From DanDude7000

Thanks for the help!
Just for clarification, the warning light has not lit up again since that first time. Do you think I should avoid driving it even though the light is not currently on?

Response From Hammer Time Top Rated Answer

No, not unless it comes on again which it likely will. You might want to go ahead and change the sender now. It may prevent it from coming back on.

Response From DanDude7000

Cool, will do.

Response From Tom Greenleaf

Just FYI - RED warnings mean biz! Shut car OFF! Whether false alarm or not this means instant attention. Check OP manually if needed but if it's intermittent may not show a real problem right then. Pay attention! Whole engine is a stake!
