    good question, your not going to get a text book answer unless that head went on the b34 normally. are there differences in valve sizes and compression chamber volume?

    If I can't sell my engines, I will part them out and you can have the head.

    Bruno,
    If you part the engines and the check valves are good in the oil filter housing , I could use a replacement. Let me know!
    Mine is a weekend driver and when I first start it it takes about 5 sec. for the light to go out and at that exact moment the 'check control/oil pressure / consult manual' warnings come up . Yet for that entire day any restarts do not bring up this warning.
    Do i need one?
    Many Thanks,
    Mike

    Mike, oil pressure sensor may be gunked up. That was the case with mine. THick gunk in it on removal. Replaced sensor (cheap from Advance or the like). Problem solved.
