Cam Alignment

Post by Warrensocal » Mon Dec 31, 2012 6:35 pm

I aligned everything so that I could pull the heads and replace the gaskets but found the heads were warped. I got them machined and also had a valve job but now I'm not sure how to line up the cams so they are in the right position. Also the manual states that the shims need to be adjusted if certain parts are replaced but is not clear on whether the shims need to be adjusted when there's a valve job. Does anyone know of a more step by step manual or link or that can explain it in more detail?

I haven't tore down a 1200 engine but have to say generally they are the same as any other 4 stroke overhead cam engine.

Cam alignments should be the same as doing a timing belt replacement. Not positive on that one.
On the Valve shims. You stated you had a Valve Job done on the head(s).
A Valve job would typically change the length of the Valve stem sticking out of the Top side of the head by at least a few thousands of an inch.

That said I would want to check the Valve lash clearance to ensure all valves open and close properly.
I seem to remember seeing there is a special tool to accomplish that.

Hope that helps
