View Full Version : smoke coming up out of the dipstick

I had this same problem with my old engine before it (the engine) blew. Now my replacement has always done the same thing. I DO HAVE BAD CAT CONVERTERS so I am hoping that is causing the back pressure sending the smoke back up the dipstick. You guys think I'm right? or could there be another minor issue like oil pressure switch or something?

You probably have blowby, usually a result of worn rings.

Make sure your PCV system is up to par.
