Ok i was just wondering because like i said i pulled the motor apart at work both the CV and the CVR and the cylinder seems to be exactly the same only the cylinder on the CVR has some diffrent carvings than the CV im not sure though

i think better buy the m speed stuff instead, thanks for your time.
