GM Intake gaskets...how long has GM been making engines?

The problem has been around to one degree or another since the General started making the first 2.8 60 degree engines. Why do you think I'm always busy at work? I'll have to ask the parts guys how many intake gasket sets a week we move in the shop.

I could perhaps makeup a standard complaint letter to be sent to GM. But it would have to copied and printed and mailed to GM by the thousands on a given day to be effective and to possibly get media attention. But I dont think the people here on this group are discipined enough to follow thru to make it efective.

What is the problem that you speak of?

Intake Gaskets go out causing coolant leaks prematurely.

I have a 1995 Pontiac GP with a 3.1L engine and I have replaced the intake manifolds twice within 3 years of each other. Since the car is out of warranty, the dealerships won't touch it under warranty. I know that this is very common with the 2.8L, 3.1 and the 3.4L engines. The issue is the plastic gaskets they use cannot handle the heat and warp after awhile. I have proof (two times).

I don't think the 2.8 had the problem. It used fiber gaskets.

My wife's '95 GA has been leaking for a year. Very small amount so she's trying to make it last until June when she trades it in.

What's the cost to have one replaced?

Ouch. In our case, our now down the road 95 GP had the mystery coolant leak which we couldn't find via pressure testing. Not a massive leak, but about a half gallon per month. My mech buddy suspected the intake manifold gaskets as he knew of the troubles with those, but we never got to where it went south on us.

We had it for 155,000 miles and the new owner hasn't yet had any major probs (knock wood)

Depends on where you have it done. I've heard the average cost for a dealer to do it is around $5-600. Precision Tune quoted me $450. My dad happens to live out in the boonies, and I used his mechanic....swapped out the gaskets and spark plugs for $325.

always use PERMA-TORGE BLUE brand intake manifold gasgets, with two cans KW block seal. get on the phone and ask for them, they cost more.
