91 2.3 burning oil

[tomw]

To check your PCV valve for proper operation, start the engine and let it idle. You should be able to place a postcard over the oil fill on the cam cover and the PCV should put a slight vacuum on the postcard and hold it in place.
No vacuum means the PCV is overwhelmed or plugged, or the passages or separator are plugged. The PCV is in the largish hose coming from under the intake manifold. It is 'in-line' with the hose, where two pieces join together near the distributor, or just behind the alternator. Pull apart and check the valve for 'rattle' by shaking it. Check that the hose leading from there to the underside of the intake manifold is un-plugged, and in place.
To change the valve stem seals, you'd have to compress the spring enough to move the cam followers out of the way before compressing the spring to remove the keepers. If you do it, wear gloves, or be prepared to have your hands cut by the sharp edges of the lobes and/or cam support bosses. The rope method works, and the air method depends on two things: 1)having the piston at TDC, and 2)being able to jam the crankshaft from turning, such as by putting the transmission in gear, not available on automatics.

Tomw there is air blowing out of the oil fill when I checked it also white mist is coming out. When I checked the line the thing rattled.

The white mist is usually the indicator of blow-by...but if it is cold where you are then the white mist could be caused by the hot gases meeting the cold air.

Compression test...leak down test...would tell you a better story...

And I used to use the rattle test on the PCV but someone (from TRS) advised me that it doesn't always indicate proper function...just a good way to tell if the valve is free...if they don't rattle they are definitely pooched though...

Blow by. You REALLY need to do a leakdown test... But compression testing will tell u SOMETHING! They rent the compression testers at MOST Auto Parts Stores!

Get a catch can... Or replace some shit! Lol...

Can't u just clean, then blow or suck on it??? To make sure its functioning RIGHT? *No homo!* haha!

Catch cans can catch cans of oil...but without some sort of pressure release and filter system (real oil separators) it can't catch enough and will cost cash to cache the oil in the can...

And...yes, the PCV can be cleaned...but I wouldn't recommend blowing or sucking on them unless you like the taste of oil...lol...or have a penchant for doing that to inanimate objects...

Thicker oil and some additives will slow down the oil and may actually stop the black smoke...for a bit...but, as I mentioned in another thread...oil is expensive and a really bad engine can easily eat up (or blow out) the price of a replacement engine over a year or two...

Best to simply look to either rebuild or replace if you can...been there...doing that...still working on the replacement.

Well, he could get a GOOD catch can.... One that even recirculates correct? With baffles and everything in it? Couldn't hurt!

I've had oil and gas pour in my face before... Just keep it in your mouth! Lol, no swallowing aloud! Sorry dude! Lmao...

I say to just get a NEW PCV valve? They're cheap as SHIT?! And either solve your problem or NOT. It provably will not though, just as a forewarning!

ATLEAST get a compression test! They're easy to do w/ a buddy and 10mins!

BTW MARK, I FEEL YOU ON YOUR SIG! HITS TOO AT HOME WITH ME AND MINE! Haha!

WHAT MOTOR ARE YOU GOING TO BE RUNNING?? N/A? TURBO?

head

Did you retorque the head after the first heat cycle or two , got to do that unless you have torque to yield headbolts, even the advertised no retorqure gaskets I recheck, also if you have the yield bolts did you replace them with new, clean all the block treads and use the correct thread lube, I have early bolts in my 86 witch really needed a retoqure after a few heat cycles, my 99 will have studs and will also need retorqueing

Definitely don't swallow gas...I used to rinse my mouth with and and light up a smoke right away...nobody said anything about second hand smoke when I did that...lol

Ah, my motor is going to be a 99 2.5 block and head with a 96 FI intake and other parts...biggest problem right now is trying to fit all that electronic stuff...may need to use the 96 dash as well, but it doesn't quite fit from what I can see...and I can't actually tear it right down till next week until I can get it into a garage...

Should be a bit peppier than the one I have now, and could be a turbo project sometime down the road...

Haha.... Nice. I HATE the way gas taste!!!!

When I was a kid, I was pumping gas for my mom (my face was about level w/ the nozzle), long story short....

.... Air bubble got caught up in the hose and... BOOM! Blew gas all in my face, they had to pump my stomach/lungs. I just remember waking up in the hospital about 6 hours later. Ha!
