Compression test
I just fitted a pair of 266 degree 9.5mm lift cams, new head gasket, skimmed head. (4AGE blue top)
After having problems getting the engine started I decided to do a cold (could'nt get it going Angry ) compression test. All were around 150psi. Previously with standard cams it shows aound 175psi (warm) is this right ?
I'm guessing there is some overlap but this would'nt be on the compression stroke should it ?
My guess is that the cam timing is out, probably why it won't start and the reason for the low pressure readings. Thanks for any help with this. TC
