how many case through bolts go in a motor?

I think I have multiple motors worth...

and are the shorter studs with barrel nuts from the heads?
how many of those does it take?

thanks in advance.

We talking T4 motors or 911 motors?

The barrel nuts are definately 911 parts. Quick glance at the others look 911 too.

There are 11 though case bolts on a 911 so I think you're 1 short. Should have 1 acorn nut and two hardened washers per through bolt. Those are missing.

Of the head studs there are 4 per cylinder. The odd one out looks to be to be a stud with a time-sert still on it making the longer threaded end appear much fatter. I think thats what it is? A couple of those head studs pretty well look Vice Grip abused and I wouldn't reuse them. Easier to just use new head fastners as they are a pretty highly stressed part.

Type 4 should have 6 through-case bolts plus 16 cylinder/head studs (8 short and 8 long).

thank you both!

I'm cleaning out crates of parts that are roughly... from the same area...
IE: 1 crate for front trunk, and another fore engine parts
I think you are correct... bet these are all 911 parts that just accidently got mixed in.

thank you!
