Title: exhaust manifold studs
Post by: jakeb on January 12, 2008, 08:24:39 AM

I am coming from the 2002 world...at least engine work...where you locktight in exhaust studs.  Do you need to do this with the m42?

Not really, but I do anyway. Not because I fear that they will back out, but more of a corrosion resistance thing. If there is Loctite on there, the likelihood that I will actually be able to remove them in the future is much greater.

I just removed my headers, and the studs came right out! I'm not sure if this is a good or bad thing, b/c I only see exhaust NUTS being sold on parts websites.

Is it okay to reuse the old exhaust studs/nuts?

those are fairly common metric automotive studs.

You should be able to find new ones that are identical online or even at local auto stores.

Mine came right out when I took the header off and I could not get the nuts off.  I bought new studs and nuts from the dealer...

I will not use locktight
