Got a 2002 Chevrolet Cavalier, which , as many know, has a metal oil filler tube coming up in front of the engine, with an intergrated cap and dipstick on the end of it.
On my car, this cap no longer scews down tightly to the top pf the tube - it is very loose, and although it doesn't come off, it takes no effort to unscrew it. It get a bit tighter when the metal is hot and the tube expands, but when cool, it barely feels like it is on.
Could this cause a problem with the crankcase 'sealing', and set of CEL's and stuff like that? I do manage to keep the cap closed, so no stuff is falling in there, it just feels like their is very little seal to the fit....
