oil problem

June 13, 2006, 10:06:12 PM

Ok I got the idle surging fixed it turns out my timing was off and the battery was dying. Im guessing stuff wasn't getting juice like it's supposed to and with the timing it just caused a big problem.

Also my EGR wasn't working. I seem to have a stiffer brake pedal now to which acts like it could actually stop the car like it's supposed to.

I noticed a new problem now. I put the Ebrake on, yes mine actually works with the original parts that were on the car which is amazing, then I put the car in gear to see how it's going to idle in gear. It's a bit rough which could be the timing. It sounds like it's in need of a tune up as well because I have a slight miss on 1 or 2 cylinders.

The nifty problem is though, I have oil bubbling out of my dipstick tube while the car is under load. The only thing I can think of is I have a leak somewhere causing pressure in the crankcase, or the PCV valve isn't working.

This is the first time I've ever had this problem though so other then what I mentioned I'm clueless on what it is. I guess I can be glad that the leak onto my headers is brown now instead of red.

Anyone got any ideas on what it is or what could possibly cause it other then the crankcase pressurizing?

thanks in advance
Dan

Probably PCV valve pressurizing the crankcase. Change that first to see if it stops it.

while your at it, get that little screen filter out of there too its below the grommet that holds the pcv valve..... it miiiiight just be clogged

the screens fine not sure on the PCV valve though. someone told me theres an oring in the dipstick could this be a possibility too?

On the stick itself, on the top of the tube, or where the tube goes into the block?

An o-ring wouldn't be there to hold back crankcase pressure anyway.
It's the PCV system's job to suck that pressure out.

If the PCV and screen are OK you have excessive blowby, usually caused by worn or broken rings

Yeah I know the chance is it could be the rings. If it is Im going to be pissed because the guy said the motor was fine. I traded a running chevy motor for it. If he gave me a motor he's deffinately getting an earfull.

On that note wouldn't a leaky ring cause smoke? A buddy of mine had a 302 in a 91 F150 and you could kill mosquitos for a city block letting it run a couple minutes. This things barely even smoking at all. My cigarette smoked more then it did when I had it running checking stuff.

A couple other thoughts because the PCV valve seems to be working. If I pull the hose off while the engines running it smokes a little out the end of the hose not alot just enough to see. But since there's air coming out that would mean its working right?

One thought is. Is it possible to have the wrong PCV valve? as long as it only has 1 hose connection on it would it work?

The other thought is, if I dont have it connected to the right spot on the manifold would that contribute to the problem?

Another thought is if it doesn't have the hose coming from the valve cover to the throttle body could that cause it?
the reason I asked is I haven't gotten to the part of changing the valve covers over from the CFI ones Im still trying to find a pair I can afford with my current funding situation.

Really, really bad rings might cause a lot of smoke, but not necessarily - my old '85 V6 T-Bird had blowby so bad that it constantly blew valve cover gaskets and always had the breather full of oil, but it didn't smoke out the tailpipe at all.

The best way to check your rings is to do a compression check. If you have low compression in any (or all) cylinder, pour a few drops of oil into the cylinders and rerun the test. If the compression comes way up (it will come up slightly regardless, but if it comes way up) this means the oil you poured in is sealing the bad rings.

I dont have a compression tester and closest place to rent tools is over an hour away. guess thats why my V6 constantly poured oil into the breather through the top of the oil cap

ok put an o ring in the dipstick and it quit leaking. yay me . I also found out my PCV valve had came out of the grommet which I found needs replaced bad. I had to make one to try and get by with for now. the cars not much above a giant piece of yard art at the moment with the way its running anyway so Im not really in a rush. Sucks though after all the work I just did to it.
