HELP!!! I think a have a cracked piston
 

I've had some problems with my oil running out lately b/c my drain plug never wants to stay tight... Anyway yesterday my oil light came on and ever since I put oil in it the engine has had a really bad shake at low RPMs and it smokes white really bad now. However, the smoke smells a lot like raw gas and the engine still runs strong as it ever has. Any ideas?

Rebuild that darn thing its probably a ring. Its 17 years old! Get a valve job done on the heads if you deside not to get new ones.
