2000 2.2l sucking oil into air intake

jtkiii · 11-07-2009, 10:33 AM

i recently rebuilt my 2.2l in a 2000 s10. apparently, i didn't get a few things right -- it has developed a pinging in the lower end. it never had much oil pressure, and was using oil profusely, but not leaking much. when i took the air intake box (at the throttle body) off, i found it was full of oil! probably 1/2 cup or more. it was in the throttle body too. what could make it do this?

it could only come in through the pcv valve, right? if a cylinder had low compression (#2 was only 75lbs), could blowby force it into the air intake? is there any other way it could get in there?

thanks.

my first thought is something is pressurizing the system and forcing the oil up there, but it sounds like you need to to a complete teardown and 100% proper rebuild. all new bearings, rings, a good hone on the cylinders, and a new oil pump.

Those should help at least with the issue you're experiencing.
