Just swapped in another 6 bolt block to my 90 GSX. Reused the head off my other block (rebuilt 5k miles ago), as well as the timing components (replaced those 5k miles ago as well). I did not reuse my mitsu 4 layer metal headgasket and went with a brand new cometic hg just to be safe. Cam timing is dead on and everything functions well, but I have a valve tap coming from one of the cylinders. When I got the rebuilt head, it did not come with lifters or rocker arms so I reused my 85k mile old 1g lifters (they never ticked or gave me a problem) and rockers. Could a stuck lifter be causing this? It is weird because it sounds like the tick is only coming from one set of valves. As I said, I rechecked cam timing and it is dead on so I'm trying to determine what to check to figure out this dilemma. I am looking into replacing the lifters with a set of brand new revised ones to see if that solves the problem. What else could this be besides a lifter?
By the way, I replaced the block due to worn piston rings. I decided to just swap in another block to save me time as I was using someone else's garge to do the work. Did not feel like just doing a ring job on my old block as I would rather save up a little and rebuild it. The head I reused had no bent valves and is in perfect condition. Any suggestions or comments would be much appreciated. Thanks in advance.
