Do the B20A motors have clearance in them between the valves and pistons so that if the timing belt breaks, a new one can be put on, or do they not have clearance like the other B-series motors. Basically, I need to know if I can change the timing belt and be fine. Thanks for the help.

 

Some people break belts and have no valve damage, with or without valve clearance. Best way to find out is put a new belt on and do a compression test. If you have a bent valve, you will know it for sure.

 

u should be good the only motors that are interferance motors are the vtecs i have a b18a and i no its a non interferance motor so i would imagen same with b20
