    whats up guys. i was driving home tonight and noticed my 88 k5 puffing white smoke out of the exhaust. when i got home there was coolant leaking from one of the exhaust leaks in my y pipe. so my guess is the head gasket. are they a pain in the a$$ to change. i have only done head gaskets on import 4 cylinders with overhead cams. it has a 5.7 tbi motor.

    It's easier in my opinion. No timming belts or chains to deal with. Pull accesories that bolt to the heads, Pull the intake,exhaust and then the heads.

    is it possible that it is just the intake manifold gaskets? . the oily is not milky.the truck didnt overheat. and it still runs fine.

    It's possible. The only way to tell is to perfrom a compression/leakdown test. That will also tell you what cylinder is giving you the problem. Either way the intake manifold has to come off.

    Intake gasket can leak water into the oil and make it milky, but cant run into the cylinders causing smoke.

    i forgot to mention. when the truck was at idle it was'nt smoking. only after it idled for a minute, like at a light, and then i gave it gas it would smoke pretty bad and then clear up until it slowed down for a minute again. thanks for any info
