Re: Help with engine diagnosis, excessive crankcase pressure?
Glad to hear you got the water leak fixed, but blow-by can only come from cylinder seal. There is nothing else making pressure in the engine that would end up in the PCV.
If it still has excessive blow by, and you cannot deal with it, it needs a rebuild. Note that a re-ring may temporarily help, but generally ring seal fails for a reason, and it's often from heat-generated or work-generated from some other issue such as cylinder taper, misshapen cylinder, etc that the ring has to work overtime to try to follow
As far as head bolts, they can be reused to "just before failure" LOL on that engine. They are not torque to yield, and although aftermarket bolts are very good, Fords typically can live through many uses. You'll know a bad one, as you increase torque, it either won't get there, or it takes more turns than the other ones as you come up to a torque setting. Readily apparent when 9 bolts take a 1/4 turn to get to the next step and the 10th is at 1/2 or 3/4 and still hasn't got there
