Ive replaced my valve stem seals in my 4agze and at the same time I am checking the clearances for the valve shims to cams.
Most of the clearances are within spec (intake 0.006"-0.010", exhaust 0.008"-0.012"), most are just within the clearances (on the wider side) and some are just over eg. 0.011 for intake and 0.013 for exhaust.
Also one on the exhaust side is 0.016 and the other shim on the same cylinder is 0.012.
My first question is that if one is 0.016 and the other on the same cylinder is within spec at 0.012, does that indicate a problem? like a bent valve etc.
Second question is, for the clearances that are only just out (by 0.001") can I just run them like that or is it best to hunt for a shim that is a tiny bit thicker.
Any input is a appreciated, thanks lads.
