Deck Height Check
 

Copied from my rebuild thread in the engine rebuilding forum::::

OK guys,

I'm back on track with my rebuild thanks to Jamie Novak who loaned me a ring compressor. I'm preparing for piston/cylinder install, and want to check the math on my deck height before I start bolting stuff together. Wayne's book says that the piston can be slightly cocked in the bore, so I thought I'd count on the law of averages to bail me out. I measured the deck height in front of each of the four head studs with no base shim installed, and no rings on the piston. I added the measurements and divided by 4. I had no gross variations in measurement. That yielded a deck height of appx. 0.62mm. I ordered .50mm cylinder shims with my pelican rebuild kit. This would yield a total deck height of 1.12mm when completely installed. Is this safe for my low-compression 2.7RS pistons (8.5:1) running stock "E" cams? I think Wayne says 1.25mm to 1.5mm, but I have some room to spare on compression (I think). What says the group... Am I safe?

Cheers!
