Lifter Ticking noise and disassembly questions - ZR-1 Net Registry Forums

Hey guys. This is continued from the discussion which has now become technical so I'm relocating it from Here:

http://www.zr1.net/forum/showthread....light=grieving

So, I went ahead and removed left cam cover after removing the plenum, brake booster and loosened the ps pump. Because I had a hard time getting to the last nut of the booster and because my steering column and gauge cluster needed work anyway, I went ahead and removed those which made access much easier.

So, here I sit with the car up on jackstands and the driver's side cam cover removed. Hoping to see a smoking gun by visual inspection, the only thing I see is two camshafts which look to be in great shape with virtually no galling or evidence of problems. Also surprised that the lobes do not look worn for as many miles it has. Maybe a mic measurement would prove otherwise?

I thought I would remove the oil pan next and check to see if anything looks awry there. I did not do a compression test. I'm guessing I am just about to the point to consider pulling the motor, but,

Where would YOU proceed at this point? Thanks
