RB25DET exhaust manifold bolts

[Lukas]

Hey all, I've got a busted exhaust manifold bolt and want to replace them all. Just wondering if anyone can give me some leads as to where I can buy some (for a reasonable price of course!)

Engine is RB25DET as title says.

Nissan is a last last resort.

Thanks! :whatsthat

Nissan is actually quite cheap for the exhaust manifold studs: about $3ea IIRC. Otherwise try Repco or a decent auto care or exhaust shop.

Hey imo.If you replace all of the exhaust studs u r wasting your money.Do the ones that need to be done and leave it at that.

i had 2 replaced and the rest were left and nothing has gone wrong with the others.

You could also get a bloke to come out to u and do it on site but it may co$t a little more.

Was it the rear ones near the firewall? These are the most prone to snapping.

I probably will just get the broken one replaced, but I've had a lot of mixed opinions... most people have said I might aswell replace them all?

Yeah it was. I have heard they are prone to breaking from old age and prolonged heat exposure.

Since its a pain in the arse to pull everything off -- particularly on GT-Rs -- I hardly see the point in saving $30. Do it once, do it right. The studs are subject to a lot of expansion and contraction, at differing rates, hence why they break. What happens if after torquing one up there is a hairline fracture and the studs breaks next day? Time to pull everything apart, new gaskets, blah blah blah.

yeah replace them all ... i replaced one when i had the head of my RB .. got it home put her together and snapped another one.. definately not worth the hassle..

and mine was one of the fronts the second time!
