98 Jimmy intake gasket

I did flush out the dex cool two years ago and replaced it with green.

I tried bar's water pump lube and sealent on my daughter's Saturn a few weeks ago. It did not work, I still had to replace the pump. Very small off and on leak. ernie

I believe most or all GM cars with plastic gaskets come with stop leak in them from the factory. The shops in town here use the brown pellet kind you crush up. They actually use them when doing there coolant flushes on gm cars. So give it a try but keep a good eye on it.

what would be the best to use the brown type or the aluminum

I'm not sure what the aluminum kind is. If it is really thick I would stay away from it. You could end up blocking your heater core with it.

Any time I've seen Barr's put into an engine (any type of Barr's), it's resulted in a clogged heater core. I won't use the stuff. Better to fix the problem.

in my experience, if it leaks in to the engine, you are drivign car with regular colant rather than oil. I noticed it when i open the oil drain plug to change the oil. too sad that i see nearly 1 pin of water flow before a single droplet of oil... I suggest you to check your oil before dribing it. I mean check with replacing it.

It appears it is not leaking in the oil. I get a smell of it only now and then. I can see around the gasket that it is leaking.
