Terry could you describe briefly the procedure you're using? I've been watching this thread and am interested in the outcome. Thanks Joe

Mark,Tried the one tooth off, did not help.Had degree bushing set at zero. Checked my degree wheel readings, first reading was 56 went to other reading it was164, total is220 divided is 110, same as all my readings. Never had a problem degreeing before.

I've never seen it happen, but I suppose it is possible that the bushing does not have any offset in it. When you loosen the bolts and turn the adjuster bushing, can you actually see the bolts move in the center of the gear? I have the same type timing set on one of our 427 engines, it works just fine. I am changing to the fast adjust, I like it better, but the hex adjust works fine.

If you get the same result by doing this you clearly built in a "mistake" in your doings..same as Bill K i had my moments when i just was too tired...

I saw the fact that you have the tip of the dial indicator on the lip of the lifter, correct? We are talking about an 1/8 in. of material that the indicator is is resting on and it has a curved surface, is this the case?

Terry Waldron · 03-26-2009, 09:48 PM

yes lifter is on the edge ,and it is not sliding off, checked it.

Terry , Put the chain on a whole crank tooth off and see what you get.

Mark Yacavone · 03-27-2009, 12:31 AM

I had to look that setup up.

You can actually see the cam advance with that set up. Something has to be slipping or moving to cause an incorrect reading.

Terry i have heard of the stock type balancer ,where the outer ring is slipping
inrelation to the inner ring, so no matter what you do , when the engine is turned over
the TDC mark can slip or move a few degrees. Never saw it personally but have
heard of it.

Stop and think about what you have done so far----try a new lifter, possibly a different balancer ,also use a different dial indicator see what happens---- I know that this next idea will not give you a correct number but pick a different cylinder to try degreeing see if the same error occurs, if it does not ,then something is wrong with the valve train on number 1 cylinder otherwise you might have a bad dial indicator or degree wheel or pointer, timing chain set up or whatever---at least you might eliminate/ isolate some of the possible variables---- Comp 387
