So I have a 91 300ZX TT. It has aftermarket custom ground cams and this engine has been apart 3 times. The original engine the cam seals leaked. I did a full engine build and put it together and the seals leaked again. Pulled it back apart and put it bak together they leak worse now than the prior times. Any ideas whats going on? If cam sprockets have issues could it cause this? Also it is just the 2 intake cam seals that leak but it is both of them every time.
