[Fot] Help! Ambro engine crankcase internal pressures. ????

[tr4racing at googlemail.com]

Hi Joe,

Piston rings would be my first guess. If the head gasket would leaking it would force out water before oil starts leaking. 
A wild idea is that your exhaust valve guide is too wide and exhaust gas is getting forced to the valve area.

 I need to develop a list of possible causes of internal pressures.

It's been going on for a long time, but the Ambro get's attention last.

This list is alive and well and I need help..................TIA

After about 3,000 RPM or so, the pressure builds and pushes oil out regardless
of methods of venting. What are the possibilities?

I really hate to pull the engine without an idea of the cause.

Is there any possibility of a crack in the head that pushes air into the
crankcase?

A list of possibilities would be very useful to me.   Finding the problem
before pulling engine would make me very happy.....begging.
