My CCV by-pass/ block off

[Ultra_Joel88]

To stop oiley hot air going in and stop prevent the intercooler pipes getting bunged up with gooey mess

Just kidding, used to have Fabia VRS demo and loved it.

Just thought I'd share the bargain-bin-v-dubbin love

What exactly have you done?

 

[Ultra_Joel88]

removed the old pipe from the crank case to the inlet on the intake manifold.

blocked off the inlet with a 25mm plastic cap from BnQ

Run some 19mm Goodrich hose down to the front of the engine bay, then used a pipe reducer to some 10mm fuel hose which connects onto a Proton fuel filter. All the oil gathers in this rather than going into the engine. Then run another pipe from the outlet on the fuel filter to a small breather pipe to allow the hot air somwhere to go.

how long has it been on? and do you think it will last long with all that oil and condensed water vapour, I would check it and often

 

[Ultra_Joel88]

It's been on a day. I plan to check it every week.

whats the control circuit like - not relying on positive ventilation is it ?

Having emptied my catch can today ... i am disgusted with the contents, some very thick goopy sludge and a load of yellowish **** ... i am so glad that's not going back down my intake!

That is what somebody is wondering on Briskoda but nobody has an answer.

What does this mean?

How long did it take to fill up could I ask?

I'd say around 4 months

 

[Ultra_Joel88]

And what amount in what size catch can was produced in 4 months?

I'd say about the same internal volume as a video cassette, maybe a little more

 

[fuey]

From what I've read it's positive venting, and the assumption that the long "elephant trunk" (read ccv tube) prevents any gunk from going back into the crank case due to the distance any gunk might have to travel.

Flapper: what impact / implications (negative or positive) can you see from this?

The aim of this is to prevent oily warm deposits / vapour from entering the air intake.
The thread on briskoda was originally created from some fella over in Bahrain (=warmer climates)

What does it mean if the control circuit relies on positive ventilation?

 

[UncleFester]

The only problem i can see is that the filter may become clogged or blocked which may create pressure in the engine - that can't be a good thing.

 

[Ultra_Joel88]

Hvae you blocked yours off uncle fester or ran it back into the inlet manifold?

 

[UncleFester]

I tried it with just a filter and it started blowing oil so disconnected it and then reconnected it with a return to the inlet for the fumes / gases whilst the liquid and oil collect in the can. That way IF the filter gets blocked it can't cause pressure to build up. I like the idea of doing it this way as you're not just relying on crank case pressure to push the crap out. It's closer to the original way it worked just minus the oil

 

[Ultra_Joel88]

I'll try it this way for a month or so and see how I get on...

 

[mike.c1979]

which is the oil catch tank? 9pardon the stupidity)
