How could a cylinder head cause a oil pressure problem? We have done many engines with Predator heads and none with a oil pressure problem. Hard to blame a cylinder head for that. Must be something else that is causing this, good luck with it, they are a great cylinder head. How has the new engine compared to your B-1 stuff so far?



No it's not in the heads. Oil is leaking past the lifter at full lift. They are chevy style lifter bodies,Isky is making new lifters(chrysler style bodies) and we are revising the lifter bushings. Yes, this was all checked on mock up,and looked/measured fine.
We are not talking about a major loss of pressure here,about 10 psi, but it is more than I will accept. The engine shows NO signs of distress anywhere else,(rods,mains,cam brgs) and could have been run all season as it was,but Tom and I decided that finding the root cause now would be better than waiting. I stand behind my engines and will do everything in my power to make the customer happy.
