Kept smelling engine fumes, decided to pursue it. Thought it was from the methanol/h20 injector. disconnected it, still smelly. Thought I might be pressurizing crankcase, so I teed a vacuum/pressure gage at hose from valve cover and ran a hose into cockpit. Getting no vac and 1-2 psi pressure at 9 psi boost. Jumps to 3ish when rapidly letting off throttle.
Should there be a vacuum there when there is a vacuum reading on my boost gage? Is this too much crankcase pressure?

BTW, M30 is old Cartech setup with IC.newer intake and still L-jet
Also has a Turbox blow off valve venting to intake. Could this add to problem?
TIA
