Def not correct. You didn't hurt anything unless you really been steppin' on it since oil change and really been heating it up and putting high pressure loads on the bearings under boost. But yea, that's def NOT acceptable. I once answered this in another thread I believe it was
@1971demon with
@Jimmy N. in agreement. "That's why I do my own oil changes, I gotta'
know what's in there"....even under warrantee I don't care. I also posted my own thread about oil changes and things I found wrong they would've never addressed at dealer.
