I'm new to the site and need help. I own a 1993 lexus es300 that won't stay running once it reaches normal operating temerature. I've been told it's a blown head-gasket but don't see water in the oil. If anyone has any advise on what sensors may cause this to happen i would apreciate it very much.

P.S. once i get it running well i will be trying to trade it for an ef or eg si hatchback here on honda-tech.com.

THANKS!!!
