Still fighting the same smoking problem. For those of you just joining, I have a '96 GT. It has this problem of belching blue smoke when you let it sit and idle for a little bit. Only happens when it idles for a while then you rev it softly or all the way down and let up. Doesn't smoke while driving or accelerating.

So, i've tried replaceing the PCV valve, and was going to replace the valve stem seals the other day but noticed something interesting.......
When i got the intake manifold off I found that it had a decent amount of oil laying in the bottom of it. Also, the #8 and #4 ports on the head were covered in oil all the way down to the valve. the rest of the cylinder ports had a light coat of oil on the head walls. But, 8 and 4 were by far the worst, i could take my finger and wipe the oil from the head and the intake manifold gasket centering hole in the head was full of oil.

So, it's pretty much got to be the PCV system, there is no other way to get oil into the intake.

So i made a makeshift oil seperator out of a mightyvac resivoir and some hose. Check out the pics, is this an excessive amound of oil? the car had been running about 5 mins to collect that much oil. Why is it doing this and how the hell to I make it stop?

:rlaugh:

Even though i'd like to the motor still runs great, has 138K on it. i'm certain it's not rings, otherwise it'd smoke all the time. still carries great oil pressure. and judging by the amount of oil in the intake, it's obviously a PCV problem. I also took the oil cap off with it running, don't have any puffing coming out of it like it has any excessive blow-by. this all basically started when i took my cats off for an off-road pipe. but i'm sure it was doing it before, the cats were just covering it up.

Anyone else have the same prob?
 
yeah, and in a 96 also. i havnt checked it at all, its been useing a quart every 3000 miles since i bought it with 57,000 on it. it hasnt started useing more, so i just said screw it. its got 108 on it now, and still the same. i noticed the smoke after the exhaust install also, and your right, i think the cats were just covering it up. i always figured it was a pcv problem anyways, cuase, thats what i've always heard. oh well, in goes the old 5.0, and 4.6 into my 82 ranger.... aint that gonna be a little bit of a b*tch?

Cool :) This means i'm not the only one going crazy.

Surely somebody here on the forums has a fix to this problem. I've heard it's a real problem with the PCV system on these cars. I looked at a '02 4.6 the other day, the PCV system is the same, even has the same baffle inside the RH valve cover that has a cam lobe right next to the opening for the PCV, throws oil almost right on the tip of the PCV.

PLEAZZZZZ somebody help!
