Re: exhaust manifold studs missing - how screwed a (archive)

Thanks for the advice - Should I use loctite or similar on the studs, or a sealant of some kind? I have had an oil leak from the front right of the engine, which I haven't been able to trace, might it have been from the missing studs in the front?

Todd:

If the threads in the head are fine, it is easy. New studs and new 9mm copper nuts (one-use). Get a 9mm swivel to put them on.

If the threads in the head are stripped helicoil. It is going to be tedious to get in there, but you could probably do it, but you'd have to remove the headers (not that big a deal, really, but lengthy depending of what else you have to get out of there). The helicoil will be stronger than the original.

I just did the removal and replacement with my E34 M5.

My car suddenly started breaking windows for miles around today - found that the all 4 studs on the rearmost cylinder are GONE, hence the exhaust manifold pipe is floating in space, and also noticed two were missing from the front cylinder as well. Holy sh*t. Please tell me I don't have to pull the engine or the head... It looks like they just fell out, not snapped off. Any info/advice much appreciated!
