I have found that anti-seize is not any good on exhaust fasteners. The heat of the exhaust soon cooks it off and after short period it is like you put nothing on them at all. It is a good idea, I use it. But worthless on exhaust parts. Good Morning, Fred E-mail message
Damon, I think in particuliar the nut and bolts should be of unlike materials. The studs should be stronger than the nut and the entire arrangement must allow some movement as the system heats up and cools down. VW has come up with several different alloys that do the job. Most of these nuts have a brass or copper looked to them. For those eight critcal selflocking exhaust nuts on the head I think it is money well spent to trust their judgement on the materials. Stainless is not one they judge to use. The other areas of the exhaust can be chiseled so I always used softer bolts with brass nuts. Remember that you may revisit your work at a later day and even stainless can get fused to tight to come loose.

Why, in particular brass nuts? Is there something wrong with using stainless hardware (both studs and nuts) for the exhaust manifold (or anywhere on the engine, for that matter)? Thanks, -Damon |
