Re-timing Cams, How To.

[SDEWY5]

Ok, well after a fun day at Eastern Creek, i blew out the exhaust gasket on my RB25, in the process of taking off the manifold, i snapped a few studs, not a big deal. Anyway, one thing led to another and i have taken the intake manifold off, exhaust manifold off, all oil lines and coolant lines off the turbo, and took the head off also. Just replacing all the seals on the top end and cam belt etc...went a bit crazy..

Now my head has had some mild stuff done to it and i pick it back up tomorrow but i want to make sure everything is all in perfect timing....i guess you can imagine why. Can anyone tell me how to place the head and align the cams with everything else? i have a fair idea but want to assure myself 100% how to do it.

Oh and one other thing, what is the best way to clean up the face of the block where the head gasket sits on?

Any info would be appreciated, thanks!

Chris.

There are any number of threads on here dealing with aligning the camshafts.

As for the block face, a stanley blade is useful for removing old head gasket. Then use a rough (around 600 grit) wet'n'dry or emery. (Dry) Rub in ONE DIRECTION only. Rub the face of the head at the perpendicular direction. eg, rub the block ALONG its length and the head ACROSS its width. This will help the gasket "grip" and prevent squirming of the head against the block.

thanks Blind, appreciate the info! i downloaded the workshop manual so whacking the head on shouldn't be a drama now. Great having the tech help so readily available!
