If you can't identifiy it by ear then you can always take off the cam covers and check the cam clearances.

I know how to tear it down, but exactly how do I measure the clearances? Thanks for all your help

With a feeler gauge you can measure the gap between the lobe and the shim ontop of the bucket that sits over the valve stem. Here is the link to the TSRM.

Mine was burning some oil. It was blowing it out the exhaust. I'm going to look through everything since I have the engine out of the car.
