there is actually alot of breathing... vent on the oil tube is open. no emissions.

What about the oil ring behind the front cover? Thats notorious for dropping out and causing low oil pressure issues.
is that something that would be so consistent?? it was 50-60psi at startup today (cold as balls outside) but by the time I got to work it was a 10psi, revs would send it up to 50 but it stabilizes instead of dropping like I hear the oring causes.. am i correct?? If I let it cool down and restart it the same thing happens...

Although I've never experienced low oil pressure due to that o-ring myself, talking to those who have - yes it is very consistent because it not being there/it being blown out causes the pressure to be low all the time as that o-ring isn't sealing at any time. But again, thats going by second accounts of front cover o-ring failure.
