I have the Lexus SC300 "92" Nice car, but when the dealer hears the word Lexus I think my bill doubles. Drained the oil today and it looks OK. The reason I thought it could be a head gasket is I found moisture in the line from my PCV valve to the intake. This and my car did run rough and I had smoke at start up. I’m thinking the smoke is from bad valve seals. When I pulled the plugs off I had a few questionable plugs. (Some what loose and dirty). I did replace the plugs and changed the oil and filter. It seems like it did smooth out a lot. I’m hoping the head gasket is okay.
