Aloha guys,
My 89 m20 engine developed a massive oil leak, it POURS it all out (not dripping) as engine runs, pressure is good @ 3+ bar (but used to reach 4+ bar).
less than 100K's on rebuilt engine., what could couse this ?
Searched various sites and "Rear Main Seal" don't seem to go bad that often, so perhaps something else gave away.,
passenger side is dry so not oil pressure sender nor anything else there.
Compression test # 1/175, 178, 175, 177, 177, # 6/185 @ 7 cranks x 2 (releasing pressure in between)
Max readings test: # 1/180, 180, 178, 179, 177, # 6/188 (@ 8+ cranks)
Cheerios,
Frank
afternoon update:
removed skid plate and oil pan is fine, so cleaned things up better and now can feel it coming from top side of metal bitch pipe # 12,
Spring # 13 and metal washer # 11 are there, not sure about # 10 "O Rings", maybe they cracked, etc,
the only question now is ... why would oil back out from there ?
Can't look in oil pan as drain plug needs an impact wrench, last oil change guys overworked it.,
I'll have to remove oil level sensor and look through there.
thanks.
