how to stop bolts backing out of manifolds
i noticed a lotta problems with nuts n bolts liking to back outat turbo manifolds and downpipes n stuff. what do you guys use to stop it ?
at first i used spring washers and read corky bell and figured that its not the best thing to use cuz the heat flattens it out anwyasy leavin the springyness none existent. it said to use serrated washers. which i will be purchaing soon.
also im thinking of getting studs instead of bolts. what do you guys thinK >? or should i jsut stick with bolts and not bother with studs and use it with the serrated washers.

crush washers. I had same problem as you, heat + vibration backed everthing out.
I put crush washers on everthing I could, never have problems now.

What is this crap?

i've had good success using studs with flat washer, then lock washer then nut.
but they are one use only cause the lock washers are typically deformed afterwards.

Re: how to stop bolts backing out of manifolds (falconGSR)
when I was having my problems I picked up some Crushed locking nuts (I beleive thats what there called). worked really well. Now If I could just find a gasket that doesn't burn up, that would be great.

Re: how to stop bolts backing out of manifolds (turboteg96)
I use studs, lockwashers and nuts=Never had an exhuast leak
Tony1 also gave me a pointer on the Downpipe bolts, you can use studs, washers, and the locking nuts(honda, the ones that are used on the studs for your exhuast manifold) He said those work really well
I hated my old setup because it consisted of bolts, and I had an exhaust leak weekly

I have never had a single problem with those bolts.
I just use the plain stainless 10mm bolts.
Until last night. One of them backed out and I developed this nasty exhaust leak... yeah... Downpipe has to come down for the 4th time in 2 weeks.... Grrrr....
I think I'm gonna look for some studs.

Re: how to stop bolts backing out of manifolds (falconGSR)
On a related note- what type of stud/bolt is recommended? Stainless or 10.9 or ??
Also- doesn't the extreme heat negate the "spring" of a spring washer?
Thanks

Re: how to stop bolts backing out of manifolds (Bnjmn)
I had the same problem with the inline pro and sc61. The bolts kept backing off. I used studs, then used a crush washer, reg washer, and nut. Tightened it down like a **** and tacked the blots.
Havent backed off again!
Thank Art for that advice!

prob be a good idea to change it howevr its not a super big deal if theres not a big leak. wont do any harm to the car.

Re: how to stop bolts backing out of manifolds (Arturbo)
All my downpipe and mani bolts used to work loose and fall out. Now I have studded everything and use special nuts (dunno what you call them) that cuts into the stud when you tighten them, been good so far.
