What are the effects of bad valves on engine performance? I did a complete rebuild three years ago on my 69 T6 engine, but recently found it has bad compression. I have great oil pressure, but bad readings when I do a compression test. The guy that rebuilt my valves doesn't do very good work (I only found that out after he rebuilt them from friends who had work done there), so that is another reason why I am suspecting the valves. Besides the effects on engine performance, what if any damage can this do to drive with bad valves (it may be summer before I have the money to rebuild the valves)? Any input is greatly appreciated.
