So all day today my truck has been choking a little with any strain. Its a tall 22r. Then tonight it just died like it was flooded i had to push it off the road at least 5 times and one time it wouldnt start. Worked at it for about 10 minutes at right aid and couldnt get it so i went to get some carb cleaner. I got it started running on the cleaner then limped it home. My dad, who was driving behind me said every time after it died it was blowing out massive amounts of smoke. Theres also oil inside the airbox and all down the throat of the carb. It runs fine for a few minutes then the problem starts up again.
Heres what ive found out:
-Fuel pump diapragm is good
-The fuel level in the bowl is where it should be
-It runs the same with the air box open
-Fuel filter is good
-Spark plugs are good
Any ideas?

 

PCV valve clogged causing all the blowby to go up the other hose?
Valve cover baffle (underside of the valve cover) gasket failed? (yes, there's a gasket there... at least on mine with the aluminum cover).

 

just put on a new pcv valve... i'll test it tomorrow.
got extra valve covers too ill check my gasket tomorrow.
its also going through about 3 quarts of oil every three weeks i forgot to add that in

 

please help i have to get to school and work

 

Blowing blue smoke like its burnin oil? How the F do you get oil in the airbox? Sounds like rings are bad and you have some serious blowby if its showing up in your airbox. Was the motor original, swap, whats the status?

 

original, nothins ever been touched, i got 120 psi on all cylinders i dont think that would cause something this severe would it?
edit: oh and i dont know if the smoke is blue, it was dark and my dad said he could just see tons of smoke.

 

color of the smoke is very important.. the color any way, white is coolant blue is oil and black is fuel.. lets all hope its black.

 

i'll find out tomorrow the carbs been having trouble so i hope thats it but i'm guessing its blue since ive got oil in the carb.
but if my carb draws in, how does oil get sprayed up onto the top of the airbox? it didnt backfire or anything

 

I had a blowby issue on my last 22r, but my PCV valve was bad as well as my rings. I was sucking oil into the airbox through the tube on the front of the valve cover that vents into airbox. I think that is what Abe was saying.

 

oh i see. then it would get drawn into the carb.
i also found that there is a little mechanism in the airbox, it has two vacuum line male connectors on it that stick through the bottom of the airbox but nothings connected to them. would that have any tie to my issue?

 

that thing

 

hey bud, im gonna PM you, Im over OLY with nothin to do, I've rebuilt and fixed, and repaired many a 22R, I got nothing goin on tomorrow I could spin out there and check out your rig. I've rebuilt these carbs to.

btw, Im to drunk and its to late but that valve should be at least hooked up or capped off on the manifold (its a big nut that comes out on the pass side of the manifold, one big hose and a smaller hose hook into it, both hook to the air box.) then theres a vac splitter, depending on non emission or cali version, it splits into 2 or 3. Cali has 2, ours have 3.

If you want i can look at it.
