Can some one tell what kind of sh$t is this? I had replaced the separator with hoses, dipstick tube, spark plugs. I can understand the p0135 and p0155-- o2 sensors got dirty:85k on them+oily crap from the intake. Almost all of oil is gone from the intake, I delete the codes. SES pop up again after 15 min driving: same 2 codes + p1085-- deleted. Third time, additional p174 p1083 p0313 show up.
Could this all be due to O2 sensors not reading data correctly. OR? Could it be due to dirty intake from separator issue? Dirty injectors?
It is kind of strange to see p0174 by itself.
Has anyone had any problems after separator has been replaced?
edit: never mind found a crack in the intake and replaced o2 sensors
