I have an 85 pickup with a 22RE engine.
A while back it started running rough, and when I pulled the spark plugs, the #4 plug was wet with oil.
Several people (some in this group) suggested that the rings were bad.
My mechanic was sure it would fail the smog test.
Well, as much as I WANTED it to fail, the emissions were very low and it PASSED the emissions portion of the test :(
Another mechanic though that there might be a leak in the intake, causing it to run rough at idle, but lean at the speeds they test for smog at.
OK, why would I want it to FAIL??
The state of California will buy your "gross polluter" to get it off the road. They are offering much more than I can get for it on the open market.
So, any thoughts on how I can get the emissions UP (without tampering with the emission controls - it has to pass the visual inspection!)??
TIA
