Okay so I did the HO conversion (minus cam, injectors, and ecm). Its all bolted up and it runs, with problems:
1. Loud top end (valve tap-but loud) type noise on drivers cyclinder bank.
2. After about a minute, does not want to idle and stalls.
I reused the original lifters, pushrods, rockers, pedestals. only the complete heads are new. I disconnected the smog pump and blocked all three hoses that went to it. a small black plastic vac line, a small white plastic vac line, and a larger rubber line (1/4" approx). I had to cut and splice the wires for the O2 sensors because they were to short to reach the h-pipe o2 holes. I plugged the thermactors holes and removed the pipe.
After I shut the motor down I hear a tick-tock, clicking type noise from maybe under the manifold or somewhere on top the motor. Hard to say I don't have very good hearing.
I am thinking my valve noise is either, a collapsed lifter (not likely, as they were fine before the build up and it is a low miles car 80K), a bent pushrod that I may have damaged when i bolted up the rockers (possible, I did not rotate the engine to bolt up, I just figured the lifter would collapse, or spring would compress as I tightened up), or most menacingly, a bent valve. I bought ebay heads which were visually in great shape, low miles, still had paint on the valve springs, but were just butcher paper wrapped, taped and shipped in one cardboard box. Perhaps dinged a stem in shipping and when it got compressed got stock.
As far as the idle, and clicking issues I'm clueless.
Please help me, I tore apart a absolutely perfectly running, purring machine, and now it isn't right, and I love the car, and I'm really feeling low right now. Any suggestions would be really appreciated.
