well i had a sohcvtec motor running in my crx and it ran a 15.9@85.6...i was running a Si tranny....along with the Pm6 computer with injectors i had a z6 dist.....i got fed up so i put back in a d16a6 motor and it ran a 15.7@88.....I recently leak down tested it and it showed 95% leak on all my cylinders and it seems like my intake valves are leaking....what should i do? should i spend 200 bucks and have the valves redone or should i just spend the money and convert the d16z6 and run obd 1....thanks in advance
