Hi Folks,

Seems that I have become the latest victim of the ol' snapped exhaust manifold studs. I was speaking to the mechanic at the garage where the car is at the moment and he has told me that the manifold has warped slightly and will need skimmed - now I have searched other threads in relation to snapped manifold studs and nobody else seems to mention needing the manifold skimmed - is it common for this to need doing? Or does it point to something else being wrong with the car (e.g. manifold getting too hot??) or am I being spun a tale (I don't think I am, as I do trust the garage and they do work on a fair few Skylines)?

One last question - where can I get the nuts for the manifold studs as my local Nissan dealer gave me a blank look when I asked for these and said they didn't know what I was talking about (Though they did manage to get me all the studs, washers and yokes, and gasket!!!????) Or does anyone have the part number to hand?

Thanks in advance.:)

Thanks Andy - I take it any Nissan dealer should stock them or are they specific to the Skyline and need ordered in?

if you want to go for high tensile studs rising sun do the whole kit for £74 inc vat, this includes the gaskets, high tensile studs, nuts washers etc etc :)

the manifolds can warp and usually you can get them skimmed although sometimes they have gone to banana and you will need to get another one.

Andy - Its at a small local garage out my way (Live in Kirknewton, but the garage is towards East Calder - near Almondell country park if your familiar with the area) - Guy called lynn runs the place, but its the bloke that works for him - Fraser - used to own a Skyline himself and seems to be well versed with them.

Pitbull - I had considered going down the Rising Sun studs route, but I was thinking that if the studs are snapping due to a bit of warping (and of course the heat), then if I get stronger studs, will the manifold itself not start absorbing the pressure and lead to the manifold cracking instead of the studs?? I'd rather have the studs snap than my manifold!?!
I would guess that this is the first time that this has happened on the car (certainly since it came acroos the pond anyway) so if the standard ones last for 70,000 miles then surely that aint too bad?

Andy M - Sorry - meant to ask who it is that you usually use when your car needs worked on? Is there a specialist in the area?

Cheers.

andy W os doing mine down right now at sp autos, he tells me he has done many of these and is putting rising sun studs with original nissan gaskets.
give him a pm, its worth travelling, i travelled over an hour away because i would rather someone who has done this before and do it quicker, as some places wont remove the studs unless the head is off.
