I had previously posted last year on the problems i had with my
96 2.2 Chevy S10. To recap, the tensioner on the cam chain broke and allowed the chain to jump time. I took the head off and found 8 bent valves. I had the head into a machine shop, had it cleaned, decked, and 8 new valves and seals put in it. I had someone else put the head back on at the time. The truck started and ran OK after all this.Now, here's my issue. At About 3000 RPM+ or so i hear what appears to be lifter noise from the engine. I cannot really detect it at lower RPM's. And i can raise the throttle in park to this point and hear the noise also.
So, my question now is what this noise could be? I did not remember hearing it before all this happened. My thoughts are maybe: A lifter mount not properly screwed down? Bent push rods maybe? I know this engine had piston slap issues and i heard them before this happened. But it really does not seem to be the same noise. Any thoughts? What would be the result of a bent push rod?
