Help! still smoking after AOS replacement

[nsbst2t]

Finally got a day off to work on this again. back on april 15th I took the intake system from throttle body to the intake manifold apart. I took a rag attached to a wire and swabbed out each tube from the top to the bottom.

Today I reassembled it. To test the AOS I took the top hose that runs from AOS to the intake loose. I rubber banded a plastic bag over the AOS tube and plugged the hole in the intake.

Cranked her up and the bag inflated with fumes and no oil came from AOS into the bag. It did not smoke much at first just the normal flat six startup. but after a minute or so (time enough for catalytic converter to heat up) lots of smoke.

I found out someone trying to help me fix the car was trying to bypass AOS and attached a hose in its place and ran the engine for a minute or so.

so...... No telling how much oil was pumped into the cylinders.


Harryrcb had said something about catalytic converter filling up and causing major smoke.

So if Harryrcb is right and the cats are full what are best options.

My father-in-law says drill a small hole and see if any oil leaks out , flush the cats with someting and jb weld the hole shut.

I know correct answer is take it apart but short on time and money.

any ideasappreciated espescially fast cheap and easy ones?

Just went out and cranked it up again. No smoke at all at first. So
I let it idle. after 9 minutes it started smoking but not like it was before.

Your #2 cylinder sparkplug is probably oil fouled. Passenger side middle cyl. check it, replace if needed & check #1 & #3 if #2 was bad then get on the hwy & burn out the rest of the oil. Just be aware if the smoke gets worse shut off the engine. The engine can Hydrolock if enough oil gets in a cylinder & bend a connecting rod, but I think you are safe unless the AOS starts dumping oil again.

I just replace the AOS and plugs. it was really only smoking on high revs under load.
after replacing the AOS is ran well and did not smoke, after driving it around easy for a while, I got on it a few times. shortly afterwards I noticed the the idle was a little high. checked for a vacuum leak and saw that I had damaged the oil filler tube while I was fighting with the AOS. took it off and fixed it, and put it back on. when I started it up again it was smoking like crazy and running rough. Tomorrow I will drive it around a little to see if it clears ups. if not, I have no idea.
