I wish I knew the answer because today, after starting my 96 we got a leaking on the drive way of antifreeze. I jacked up the car and let it run trying to trace it. I see a little pool/bubble of antifreeze right between the heads on the drivers side. I am assuming the gasket on a car that only has 52,000 miles! Anyone know how much has to come apart on top to get at these gaskets? How many hours? What a service garage would charge?
Answeryes there are problems with the gasket (there is a recall / tsb ) for certain models. the most common failure lets coolant and oil mix. teltale sign is low coolant frequently and if you pull the dipstick the oil looks like "cocoa".i have a 96 with the 3.1 and from research i have done it appears the "permanent" dexcool antifreeze eats the gasket. I'm in the Chicago area and it cost me $512.00 to have the job done. the problem is with the lower intake manifold gasket. go a "Google" on lumina lower intake and follow the leads.take it to a mechanic
that's what it is, i have a lumina, had same problem, replaced the intake manifold. run like a top since
if you had it heat high enough it very likely worped your heads and or damaged the head gasket
Simple method... get some carb cleaner or starting fluid. With the engine running, spray the area where the intake manifold gasket is. If you experience sudden bursts of increased RPMs, you have an intake manifold gasket issue.
Yes, you must install a new intake manifold gasket.
The intake gasket is the gasket that conncects from your air filter into your intake manifold
Between the intake manifold and the cylinder head.
between the head and intake manifold
i had this problem the intake manifol gasket is blowed
Assuming this is a 4.3L engine, the upper intake manifold gasket would be between the upper intake manifold and the lower intake manifold.
Intake manifold gasket
Sounds like a blown headgasket or intake manifold gasket. Sounds like a blow intake gasket to me...It happened to My 86 Mustang and my 96 Lumina.
