So I slid in the Comp xe270hr today. Put on the retaining plate. Went to bolt on the timing chain pulley and as I tightened down the timing pulley the cam slid forward about 1/8 - 1/4 inch. Is this normal?? Help...........
Some movement is normal, but that sounds a bit excessive. There should be thousandths of an inch of movement, not tenths. Is the thrust plate excessively worn?
I agree Grady, but that much movement fore and aft sounds excessive. We're talking .125-.250 inch based on the description he gave. IIRC, cam endplay should be around .005 inch max. Too much and it'll allow the cam to walk forward and push the timing gear into the cover.

Sounds normal to me as well. The cams will slide around a good bit before they are bolted to the timing gear. Once the timing gear is properly torqued the endplay should be like Matt is saying.
I believe cam end play is 0.001"-0.007" up to .010" or so.
For what is is worth, my camshaft had a lot of movement as you described and I went 30k miles with it with no problems. I did not for see any problems with it.
all it did was pulled the cam away from the freeze plug in the back and butted it up to the cam gear on the chain. It all depends on the depth of the freeze plug in the back that sets the back and forth while the plates on. when the cam gear draws the cam to it and the dampner pushes tight up against the drive gear on the bottom the only slop you have is the slop in the chain.
