[Healeys] Question

After bragging about our 100M's compression numbers I have a concern. We seem 
to be getting a lot of pulsed pressure in the valve cover, as felt at the oil 
filler hole. There is very little pressure at the end of the road draft tube. 
Given we have good compression, so, theoretically shouldn't have a lot of 
blow-by, what could cause pressure in the valve cover? The engine was totally 
rebuilt, and I believe we cleaned out the road draft tube but don't remember 
for sure (we were otherwise pretty careful). 

All hints, ideas, even knowledge welcome. 

TIA, 
Bob
