New to the site and have been searching but cannot find an answer. I picked up a 1995 Ext cab 2.3 5sp dirt cheep that was towed behind a motor home in first gear for a mile or two, engine was over revved and the valves were bent. Bought a used head, cleaned everything and installed the head & new timing belt w/tensioner, engine ran but was real sluggish. Used a timing light and checked the timing and was at 15deg BTDC The longer the engine ran the more the timing would change and it went to 28deg BTDC Stopped and restarted engine and the process started all over again. Well that engine locked up so I bought a used engine and installed it today and I still have the same timing issue, no CEL, starts easy. Any ideas?
