^ 20 & 15 could both be from an over-oiled filter, but 20 is a bit less likely…

 

All engines have some blow by. This is gases that get passed your rings. The engine needs to vent them. The PCV (positive crank ventilation) is designed to draw these gases back into the intake manifold to be recycled thru the engine. Emission wise these fumes are worse then normal exhaust because they could still contain un-burnt or semi-burn fuel.

The PCV needs a fresh air supply. Of course they want it filtered so they pull the fresh air from the already filtered air in the air intake.

In a engine with everything working right there is always clean air being pulled into the motor so nothing can come out of the tube but if the PVC system stops drawing air into the intake your blow by has no place to go so it goes out the tube and into the air intake, The blow by gases can carry oil with them. So now you have the soot from a semi-burn fuel that may be carrying oil with it in your intake.

The real downer is if your PVC system is working and you still have the same condition. This means the motor has so much blow by that the PCV system can not keep up and even through the PCV system is working you are still pushing exhaust and oil into the air cleaner. this or low oil pressure are the two main signs that the motor is about done for. There is no simple fix for a motor that is over running its PVC system.

 

ok gorn now your very intelligent do you mind to break that down into lamens terms for me to process lol

 

When a cylinder fires the exhaust is suppose got out your exhaust pipe but a small amount of exhaust sneaks past the rings. If your engine did not have a vent the engine would build up pressure inside the crank case (where the oil is kept).

Now let’s say you garage is the crank case and you have a running car in your garage. You need to vent the air, you can open a window but it works a lot better if you put a fan in the window. Then that works better if you open another window on the other side of the garage. This allows the fan pull the dirty air out of the garage while also pulling clean air in.

The fan is the PCV and the other open window is the hose coming from the intake that is getting oily. When the PVC fails it’s like taking the fan out and closing it. Now all the dirty air goes out the open window. In the case of your motor the dirty air is carrying oil with it.

In a heavily worn motor even with the fan on and working there is too much dirty air being made for the fan to handle the volume so now there is dirty air going out the window with the fan and out the open window.

Better?

 

My 69, and cars of that vintage has a PCV valve in one valve cover, vented into manifold vacuum. The other valve cover has a breather vent. Other cars came with a breather tube to the air cleaner. My LT1 Vette has a breather tube from one valve cover to the intake manifold. The other side has PCV valve in the intake manifold looping around and back into the intake manifold (crankcase to manifold vacuum ports). At least the engine does not have a vent tube going to the intake plenum to goober that up.
Yeah, a "sealed system" like this is better for the atmosphere, but not so good for the engine IMO. If I had blow-by issues like this guy appears to be having, I would want to isolate the vent tube from the intake plenum to keep the oil out. The PCV hose he has sucks towards the engine, except for low vacuum situations (high throttle), where the oil fumes are getting sucked into the throttle body due to intake vacuum. To me, that's counter-productive for an all around happily vented engine.

 

I agree with a stand alone filter, getting oil in the intake is not good. We use to do that on the old school V8s all the time. Some where so bad they would fill up the air cleaner with oil and start to soak the paper filter.
You just want to be sure you have a filter incase it is drawing in air at times . This is the kind of thing a old school V8 would have, We would just remove the hose to the air cleaner and install on of these. the filter would get dirty but it would keep the oil in the motor.

thanks guys ill give that little filter a go cause im tryin to get the most out of the car before it goes yall been heaps of help

 

I've used those kind of (exposed) filters before, but they tend to be a dirt magnet. Even though they look niftier, I'd opt for an enclosed type breather. Does the 3.4 have 2 PCV valves, one for the main crankcase and this one in question that goes to the air intake? A venting system needs an in and an out side.

 

1 pcv valve on right side (lookin at the car head on) and on the left side had a long black metal tube that goes from the air intake to a rubber grommet and that goes into the valve cover. But i was doing some research and that long black tube on the left side seems like its a 1/2" too short and doesnt fit in the rubber grommet tightly and was thinking about replacing the tube and the grommet.

The guy i bought it off of said he had the motor rebuilt but i seriously doubt it and everym time i turn around im finding a patch job after patch job.

Im dealing with alot at the moment like a preemie in the hospital and this car is about getting on my nerves so i really do appreciate all the help and if me explaining all this doesnt help ill record everything and post it on youtube so yall can see.

the question i was gonna get to is should i buy a nice oil catch can or buy these breathers?

 

Your oily vent hose is on the left side when looking straight on, correct? Put a breather at the source on that one, leave the PCV on the opposite side connected as it is now.
