Inlet stud help - Ricky - 08-05-2012
The smaller inlet manifold stud has ripped the thread from the block, probably making my boost leak pretty tragic.. Anyone used a helicoil device on these? Are they difficult to do and does anyone know what thread size and pitch they are?

Should be standard m8 if I remember corectly.
Re: Inlet stud help - Ricky - 08-05-2012
Thought so, what about thread pitch?
Re: Inlet stud help - Ben - 08-05-2012
m8 x 1.25 would be my guess but don't necessarily trust me!
Re: Inlet stud help - Ricky - 08-05-2012
Cheers, might see if I can get hold of a pitch gauge, and a helicoil kit. Bet it's going to be a bugger trying to drill a hole with such little space to move!

Meh, I run with a few missing... As long as the gasket is good, it'll be fine, I wouldn't worry too much tbh, not worth stressing over.

fitted a new gasket a week or so ago but I don't think its sealed. its a fibre one I'm guessing the best one to get is the metal one?

You have guessed correctly

Just picked up a new gasket today, my girlfriends dad is going to fit a helicoil for me..its nice having a mechanical engineer as a future father-in-law!

See I have mixed opinions on this.... when I did matts, it wasnt quick clamped enough on a few of the studs and was pissing at about 24psi... retightening them sorted it... so I would have thought having some missing would be worse.... if you have boost problems then I would get it sorted, but if the gasket is good and there are no boost issues then I wouldnt worry.
