Exhaust manifold studs/bolts
« on: 19 July 2010, 13:37 »
Anyone tried these?

http://cgi.ebay.co.uk/VW-Mk1-Mk2-Golf-Rabbit-Stnls-Exhaust-Studs-Lock-Nuts-/380237441045?cmd=ViewItem&pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item5887eae815

We have the head off and a couple of exhaust manifold studs are missing, might as well replace the lot while its accessible.

stainless bolts are barstewards for self loosening,  and its very unusual to get a grade as strong or tough as there steel counterparts. so they shear/snap easyer. the advantage is there going to undo easyer  10 yrs

but i've had manifolds on other cars snap studs off before and its a pain in the hole.    stock maniolds never had a problem with but some aftermarket stuff where all the holes have been quite tight to the studs have caused problems

I would of thought stainless steel would be better as the fixings won't seize, so won't snap.

just get copper ones from GSF, cheap and they work :)
I doubt you would own the car long enough for you to worry about any possible seizing issues, whenever I have come back to my copper nuts they have undone fine. although i haven't tended to leave an engine in for longer than a year so far  :grin:

Will copper not go soft and break up?

Personally i'd go with stainless steel. Especially if you are keeping the car.
