GM is at fault for the failure of intake manifold gaskets in several of its vehicles

yah this has been out for a long time now, well up here anyway, felpro makes a metal set of gaskets that replace these, waaaay better

my dad owns an auto parts store up here that i work @ and we sell all sorts of these gaskets sets, and they come with the metal intake gaskets, and valve cover gaskets(not metal) and a lot of little stuff too

and dont get the repair work done @ gm, too much money, at least thats what we've run into up here

part #s are MS98000T
MS98001T
MS98002T
MS98003T
MS98004T

all fel-pro

No!!!! GM???? Sorry, I refuse to believe that crap......


GM would never screw us poor consumers...

Hey Josh, great post & infor. I knew when I read the information that it was
written back in April 06, but I never read that information before & thought
it was worth the time to post.

Sounds like the members now know
who to contact for parts Peace`Space

Mr Montejass, Believe.....Believe....I know the truth really hurts : (

When are you getting that 06 Monte ?

seen that happend on alot of 3.8l anyway i have a question is the front valve cover gasket hard to change on the 38 sc?

possibly going to by one, oil leaks by the front valve cover onto the ehausht manifold

hell if i tear mine down that far im putting ina better cam then i have and some better lifters to .

Seems lke a good excuse to explain to the wife why i need to tear my car apart LOL

but it will have to wait till the "big Move" happens. if they would ever come off a date it would be real nice. but at least i knwo what i will be doing if i notice water in the oil so far all temps and presures have been in the good to floor range so i have not thought of this to much . but i do watch them pretty close also .

i dont believe the 3.8's are having any problems though are they???

i think its mostly the 3.1's and the 3.4's

I was at my GM dealership for something else one day a couple years ago-- an oil change I think, on my lunch hour. While there, the mechanic told me he thought the aforementioned gasket was badly worn and that if I didn't have it changed out, there could be oil/coolant mixture as noted in the article. As he could see my skepticism, he assured me that the repair would be covered by my warranty. Now, I don't know if this is a real issue or if it's just a way for the dealerships to stick it to GM, but I let them do the work. I wonder how many people they gave the same line.

Was it on your '02 SS? If, so, how many miles a that point?

i dont think gm cover's these under warranty, they would lose too much money. its their fault but i dont think they cover it

It was on my '02 SS, they said it would've cost about $600 and they billed GM. At least,
that's what they (Smicklas Chevrolet in Oklahoma City) told me and they didn't charge me a dime.

Oh, and mileage was about 30,000 then.

it does mainly happen on the 3400 engines i have changed out a lot of the ar diffent shops i have worked at though not a common it does happen on the 3800's too

well hopefully it doesnt happen on the new montes

The new monte's do not have a plastic/composite intake manifold.

oh yea no duh huh lol didnt think of that for some reason

Glad I got the 2004 with the 3.8

Yes they do... the 5.3L V8 in the SS does at least... don't know about your V6's though...


From Chevrolet.com site about the 5.3L V8 engine:

"Composite Intake Manifold — the composite intake manifold design allows the small block V8 to deliver high levels of torque at low- and mid-range engine speeds, while still delivering plenty of air flow for peak engine horsepower."

its also the dex-cool(red antifreeze) that causes this problem too

there is a way to switch your car over to green, and that is to have the rad system drain completely and boiled out, any rad shop can do this, and then refilled with green antifreeze(way cheaper and better on the engine

yes the dex cool does eat up gasket it eats up paper gasket bad the 3.9 and 3.5 have a aluminum intake the 5.3 is the composite, my truck had the composite it was a 5.3 but i never had any problems with it leaking had over 100000 miles on it and i flushed the systems once only problem is the water pump gasket had to change either due to the dex cool and lack of torque to the bolts when i took the bolts out of the water pump to change the gaskets i didnt even have to break them over, they were loose ? gm should of put lock tight on them, i build hydraulic winchs for a living and i know all about gaskets wear and tear and seals leaking, the dex cool is for aluminum blocks, heads and, intakes, helps prevent rust and has a very long life spand, also it is animal resistant.
