What Dougal said!

ah thank you! That would have been a very interesting learning experience.

Thanks Didiman. Unfortunately my manifold isn't on that list, but they all look so similar. I guess if they are the same thickness it will work.

9041308400 is the P/N for the 4BD1T manifold studs, M8x1.25 thread, from what I could find...

I used M8 socket head cap screws from coventrys fasteners. A few years and many hard km's later and they haven't budged.

Thanks guys, i'lll do that.

Does anyone know what thread the oil feed for the alt is as it comes out of the block? I don't have anything that matches the thread (very fine?). The return is 14M1.5 so I assume it is metric..?

Can't remember now. I have a feeling it may be BSPT or NPT, not metric. I just removed the fitting and took it in to pirtek to see what they had.
