The Stovebolt Site Forums The Shop Area Engine Shop little smokey

Hi guys, just have a few quick questions for ya... my neighbor has an 82 GMC truck with a stock 350 that he says I can have if i'll haul it off for him... he says it ran good when he parked it in summer of 2003 just after he drove it home (less than 2 miles) after getting t boned by a cavalier.

My question is this... I have started the engine successfully on 4 or 5 different occasions and it runs ok... however after letting it run for 4 to 5 minutes there is definitive oil smoke that is coming from just around one of the spark plugs. At least no other obvious leaks or anything. When this happens I go ahead and shut it down. I would not label the smoke as "major" however I also do not want to cause it to get any worse either. I DO understand why the smoke is there (oil on a hot engine etc etc) but not sure if this can eventually go away or will it keep getting worse? Is this something where I just need to tighten the spark plug or is there something that I need to do to fix it? Is it possible that its just the spark plug not seated properly in the block and maybe a new one would stop it? Since it is only a little bit of smoke can I go ahead and run it for a longer period of time without causing more of a problem?

Your help is greatly appreciated.
