okay ive got a problem and im not sure what the deal is....oil keeps gettin pushed up my dipstick like the crakcase has no where to vent or something...but both of my PCV valves are new....i just put them on this summer but i havent exactly blew thru them or anything in the last few months to see if they are clogged but they look really clean....anybody else have any idea...??
thanks

Both of your pcv valves.. that is probably why. Your car is only supposed to have one. Can you draw us a picture of how you have these valves routed? One should be supplied vacuum from the intake port between the drivers side runners. The other side should connect to the throttle body to allow clean air in.

im pretty sure there is suppose to be two i got one in each valve cover and most pics ive seen of other tuned port cars have the same set up

Only one PCV here:



You may be confusing the CCV tube for a PCV valve.

One PCV valve per engine. It is on the driver side valve cover and has a hose that goes to the ntake manifold. The passenger side has a breather line that runs from the valve cover to a port on the throttlebody, just a piece of pipe/hose, no obstructions in it like a PCV.

hmm. i must be confulsing the CCV with the second PVC but there was one there when i took it out cause i tried getting everything new when i bought the car which i havent had all that long. ill have to look into that passengers side problem...so the CCV does vent the crank case?? is that right... and also can i just get a plastic elbow and put it in place of the PVC?? thanks

Morley

On yours I believe it is a palstic elbow coming off the valvecover and going to a hose that hooks to the TB. Shouldn't be too hard to find a replacement part in the auto parts store.

strokedtpi

so do you guys think this is what is causing the oil to run up the dipstick or could there be somethin else??

Morley

It is the most obvious possibility.

yup, sounds like the most obvious culprit to me.. make that pcv system functional and see what happens....

Just how much lubricant is in your sump, anyway? Incorrect dipsticks can cause oil overflow. Fuel, coolant, or condensation in the oil can also cause oil displacement. If you haven't already done so, you might want to visually inspect and smell the oil on the dipstick.

A change (with filter) may be in order anyway, since your new acquisition may not have been refilled correctly, and the lack of a functioning PCV system will contaminate the oil in a very short time. Changing the oil is also a good excuse to get under your new ride and take a very good look around. Take a grease gun with you to get fresh grease through all the fittings on the steering/suspension.

ok here is the deal it seems that the throttle body isnt pullin any vaccuum on the line that goes into the pass. side valve cover....should i just put a breather on it or is the throttle body just gummed up???


if i wanna do the breather route what kind of recommendations do you guys have...thanks

Morley

If the TB isn't drawing at all from that port then it is plugged up, either on purpose by the previous owner, or there is a ton of crud in there.
A breather would work ok..but you really need the positive draw on the crankcase that the TB provides.

The pass side hose isn't supposed to draw a vacuum. The pass side allows filtered air to enter the crankcase, and the PCV on the left side draws the air (along with the fumes) out of the crankcase. There's supposed to be a cross flow from pass side to drivers side.

strokedtpi

where is this crossflow...on the drivers side i just have the pvc goin to the intake wchich does pull air--is this suppose to go from divers to passenger or..... ??

MrDude_1

imagine it this way...... clean air comes from the throttle body down that hose into the passenger side head..... its pulled thru the pass side head into the crankcase where it starts getting dirty.... it then goes back up the drivers side head and out the PCV and into the intake... where it goes into the chambers and burns......


the "crossflow" is inside the motor... it IS the motor...

strokedtpi

alright i understand now....as of now i for some reason have a pvc valve in the pass. valve cover....should i just try and find a tube or somethin that fits and run a hose line to the throttle body or do you think it would be okay to just put a breather on that side.

MrDude_1

from what i was told in a diff thread on this msg board... you need to use the TB port if you have a MAF system....


that way, it gets metered air and not unmetered air that the MAF hasnt detected.


if its speed density though, you could.

strokedtpi

alright mine is SD so i might try that if i cant find somethin else to fit snug in there and then size it down to fit the hose to go to the throttle body...... so im assuming i should just plug the line coming off the throttle body right??
