I noticed that the bolt seems to sit on a slant, but cant tell if this is the design or if its inserted incorrectly. I won't be messing with it until the next visit to my indy, but wonder if the bolt is designed to seat a little bit off kilter to facilitate oil draining or "sump-thing". I was inspired to look by the recent post about some goop on a hose. the bolt is tight, and has no oil seepage. It looks like the oil drain plug, but I haven't done any work myself on the car yet and honestly can't be sure. the wisdom of the renntech will be appreciated.

It is supposed to be on a slight angle. This is a Boxster which has the same thing.


Thanks much for this reassuring message. I thought it just might have something to do with oil draining issues, and I appreciate your follow up research. Loren can add this to the "porsche mysteries" forum. Best, jl
