    I am about to buy an 88 Chevy Silverado. It has a 350 and one hell of a shift kit. The motor smokes and uses the hell out of oil. I was wondering what is the cheapest way to stop it frm smoking or cut it down. I had heard that if i use some Lucas oil addative it might help it some. Is there any truth to this?
    Thanks

    All depends on what is causing it to smoke. If it is the rings you are pretty SOL and time for a rebuild. If it is valve seals they are easy to do if you dont feel scared pulling the heads off the block. But in eather case you can try running 30w50w oil and it will help.

    Well it could be a blow-by problem. I would recomend checking out the seals and bearings. If alot of stuff needs to be done I would just get the standard Crate 350 I think they are around like $1400 starting not sure though so dont quote me on it.

    It doesnt scare me to pull off the heads. I dont really think its the seals. I will probably look into a rebuild kit.

    take a stroll down the save-your-engine-stuff isle at your local auto parts store :big grin:, check out that stuff that promises to stop smoking

    Someone told me it could be a stuck valve. If it was, how would i go about checking it?

    compression test is the first thing i would do. if you find a low cylinder, put a teaspoon of oil into it. if compression raises significantly, you have bad rings. if not, it's either a)head gasket, b) a bad valve seat or c) a sticking valve.
