BACKSTORY:
Car was running ok before I had some maintenance issues I needed to address. Mainly loose converter bolts and a crank bolt that almost backed out. And by almost backed out, I mean I could easily turn the bolt by hand when I checked it.
While the car was down, I figured I'd pull the oil pan since I hadn't done that on this motor yet. Everything looked good other than an oil jet tube in the pan, but no metal shavings. So all in all this is what I did:
• Locktite and torque the torque converter bolts
• New crank sprocket (old one was chipped and seen better days)
• New harmonic balancer (old was in rough shape)
• Replaced all oil jets with stock DSM style jets (verified they clear pistons and crank)
• Locktite and torque crank bolt
• Also threw in some HKS 272 cams to replace my BC 272s
All the timing components have a few thousand miles on them so I reused them, triple checked tensioner arm gap and verified the timing marks lined up. Cam gear dowel pins were straight up, cam gear lines were horizontal with the head, and I had 39 timing belt teeth between the outer cam gear lines.
PROBLEM:
Now I have this tapping noise and I can't for the life of me figure out what's making the sound. I changed a lot so I'm not sure where to check, but it definitely is coming from somewhere on the timing side of the motor.
