My new CCV system...Version 3.0 - Page 3

Just had a though. Can any one think of a way to make this a maintenance free thing and have the oil return to the crankcase ( other than punching a hole in the pan

)

only issue I've had with my set up is that the vapours still make it out the filter, may put some stainless scrub pad in there to see if that helps.

Inlet and outlet hoses seem to be the same color, s oya, throw a scrubber pad in there. Works for me !!

doc_m · February 15th, 2006, 12:40

would ya put some scrubber pads in the hose or the filter itself?

I am putting scrubber in my can. I am going to use copper as it was all there was at the store when I went. My can is just an empty can with a tube that will show the level of oil within the can. Nice little touch. I am hoping that the scrubbers will allow all the oil to drip down to the bottom. I am going to install a drain in the bottom before I install it. It will be done by thursday and I will post some pics of the original can and the mods I will do to it to make it work. Then we shall test it.

I don't think this would be a good idea as these from what others have said are also collecting condensation and you surly don't want that in your crank case.

isnt part of the solution to the excess ccv flow going to be slowing the flow? all of the air vacuumed by the vacuum pump from the solenoids/booster and any leaks goes into the valve cover and then the crankcase. I must be 70-80% of the flow. Yes, no? Or is it just my logic that sucks?

From what I know the blowby from the cylinders its whats coming out of the ccv and into the intake. It is already a low flow and what we want is to remove the oil mist from this blowby before its sucked into the intake where it mixes with the carbon from the egr. The dry carbon mixed with the oily mist is what sticks to the egr, intake and builds up and cloggs up. There is also water vapor and if allowed to condense and then put back into the crank case will contaminate the oil. Sure, the oil gets contaminated but why add to it.

I might be dumb here but I don't see (anywhere) any input into the valve cover. Ok! I see that the vaccum gets routed back to the crankcase

. Only out and thats the ccv. We want it out. A catch can or filter to catch the oil mist to help slow down the crud build up in the egr and intake.

I will then assume that if the vaccum gets routed back to the crankcase then any water vapor should evaporate (after the car is heated up) and go out the ccv then into the intake to be run through the system. Odd indeed.

most of the ccv flow is not from blowby, but from the vacuum pump's output into the cylinder head.

Wingnut
How has ver3.0 worked so far, free flow all winter?
Thinking of going to PA for the parts tomorrow, just want to hear its working.

There was an official fix for this!!! It could be rather dangerous if the engine starts running away... I had a VW dealer fix it under "goodwill" on my 1980 Diesel Rabbit... they replaced the housing that comes out of the crankcase...

Get something done... soon...

Very very dangerous! My '79 use to "run away" going up hill. Had to try to hold her back with the brakes. The oil would build up and dump into the intake when going up a incline. She would take off like a jet and just pour black smoke out the exhaust. Would not shut off with the key, just keep on running until that heavy oil was burned. Finally one day she blew. Couldn't get the local dealer to do the goodwill fix. Think in '81 or '82 they claimed to have solved the blow-by problem.

How is this going. I have been thinking about doing something like this..
I had a similar set-up on my 20v. But I used a Water seperator from a compressor.

Just installed the wingnut version 3.0 CCV filter evrything was in stock at Princess auto parts about $50can for the parts 1/2 hour later done.
Thanks Wingnut.
I'll report back in a few months.

Fortuna Wolf · May 14th, 2006, 14:41

Oooo, I don't have a princess auto parts down where I live, but I'd love to do this. If I can't find the parts locally, can someone ship them to me?

Also, instead of using steel mesh (I'm visualizing the steel scrubbers I use on pots) what about using stainless wool? That oughta have a higher surface area.

Edit: hmmm, ah, I see that I can order from princess auto online. They ship to the US I imagine?

What do you do with the filters when they fill with oil? Do you wash them, empty them, or replace them? Would it be possible to punch a hole in the bottom and plug it to use as a water/oil drain?

i've been running my 3.0 set up for a few months with no issues and couple minor changes with scrubber pads but other than that been an awesome set up thanks wingnut once again for a great suggestion
