Yep. Ive never cleaned my engine <135,000 miles>..
Im very concerned. Near the Cam sensor on the top of the engine alot of oily residue is all around it. On top the Intake Manifold where the pipes go )))) down into the top on the engine theres oil reside there too.

is this normal for an unclean engine or you think im having seals go.??
Please Help.
