Well man if ya dont really want to tak it to vally, We could always take off your head and cylender,
Its a SMALL job, nothing to it, Take the head first and take it and get it checked, and well its off see if we can see somthgin wrong with the piston and ring, and it we cant see then we will take the cylender off and take a look
I did it on the CR and there is nothing to it my man
