Re: oil pressure problem
it was a aftermarket gear I'm not sure if they come with a bolt or another washer to use it had started to wear on the key-way i had a friend turn the crank while i watched the the cam gear and seen the play..but after i changed the gear it lost oil pressure so I'm not sure if the cam gear was the problem or if the oil pump was i have it tore down now oil pump out looked at rod and main bearings they look good going to put pump in and see...

Re: oil pressure problem
Well, if it was wearing around the keyway, that's no good, but I doubt it was making noise...
Usually, if you hear an unidentifiable noise, get a mechanic's stethoscope, and start poking around areas under the hood w/ the engine running. until it gets it's loudest... it's in that area.

Re: oil pressure problem
When a bolt came loose on my b16 the car ran like ass, wouldnt move and make the most horrible clicking noise.. just from loosening one cam bolt, cam never came off either. I couldnt explain it.

Re: oil pressure problem
25 PSI hot is not good.. it should stay around 40-60 constantly.
You may have worn bearings, you should look into that.
