Does anyone know where you can pick up a nut like the one pictured on the left with the shoulder flange? I have 8 and need 12. Would like a few other sets as spares as well.

Are you talking about copper coated? They are still currently used on newer Porsches and should be easily attained at the dealership.

They're still currently used on WATER COOLED Porsches. They were NEVER used on air cooled Porsches.

Hey Cap'n!

Tell me true. Are you saying that the nuts in copper with the flange were never used on 914 2.0L motors on the exhaust studs?

Pelican only sells the ones on the left.

I want to know!

Thanks!

John

I don't have time to take a photo, but here's the truth. 911s DID NOT have copper plated steel self locking nuts anywhere in the exhaust system. They DID NOT have ANY kind of self locking nuts anywhere in the exhaust system. The Bird sells locking nuts for half the studs, non locking for the other half. Why is that? Because they can, I guess, and it simply doesn't make sense. They're in the business of selling parts, not repairing or restoring cars, and their advice should be taken with that in mind. 911s came with 6 non-locking barrel nuts on the 6 studs accessed through tubular holes in the HEs, and 6 plain old conventional, non locking, 8mm nuts, 13mm wrench size, on the other 6.

ALL 1.7 and 1.8 914s came with what look very much like plain 8mm nuts on the exhaust studs. However, despite the looks, they're different; They're helicoiled. The same nuts are used on the studs holding various sections of the transaxle together. All 1973 and 1974 2 liter cars used a relatively bulky looking thickly flanged 8mm nut with a helicoil inside on each of the exhaust studs. I don't remember what kind of exhaust nuts the '75-'76 cars used, but I can guarantee it WASN'T any kind of locking fastener, same as the earlier cars.

That's the truth. Anyone telling you any different doesn't know what he's talking about, or he's trying to sell you the product he has in stock.

In my office at home, why?

Oh, you mean where am I working? Stinn's Autohaus, about a mile from the old shop. I'm the parts guy, as well as turning a wrench or two as needed. Not good to call me at work, just e-mail or PM me.

I didnt want to start an new thread for almost the same question.

Where do I get new exhaust studs other than AA?
I was surprised to find that Pelican did not have them.

I found some with the right part # (N014 397 9 - 8X56) for a 2.0L on evilbay, but I think I would trust AA more than that.

Really? I wouldn't trust all-thread, but a standard bolt?

I thought about it but figured there was something special about them.
Either a slightly enlarged thread to stay in the aluminum better or the taper.

Ace carries grade 8 black metric bolts in the necessary length
