Crankcase Bolt Question

[eR1c]

I found a bolt that appears to be cut and another that appears to be missing from my crankcase ...it's at the very end of the crankcase towards the rear of the car. (this is for a 930 turbo). -see photos below.

The yellow arrow shows what looks like a cut bolt. -was there supposed to be a nut on this end? The other end not shown has the nut still attached. ...it occured to me that maybe this is how it's supposed to be. when I look at the photo at high resolution it looks like the bolt wasn't cut, and there appears to be a lip or overlap ...the cresent shape between the bolt and crankase (see 2nd photo).

The pink arrow shows a completely missing bolt. -or was this left empty for some option or something? -should I get a crankcase bolt for it and bolt it tight? ...nothing is leaking from this area so not sure I should even worry about this?

That is the back end of a stud going the other way into the case, and the hole accepts a bolt.

thanks John,

so that's good news on the stud, ...looks like the hole is missing a bolt then? -I see them on PP's for less than $5 including nut, etc... should be an easy fix.

Don't worry about that hole. If you look at it some more you will see that it just goes through one of the two case halves. So it doesn't serve to fasten one part of the case to another. Just why it is there is another question, but it doesn't represent anything missing.

If you look at your case from the other side, you will see that all the case rim studs appear like the one John set you straight on. The one that puzzled you just, for some reason, goes in backward, so to speak. When disassembling or assembling a case you need to remember that not all the nuts are on the same side.
