Those Who Run Pcv Venting To Atmosphere....


550

Recommended Posts

So I decided to try venting to atmosphere again.... annnnnnd the same thing always happens. I get an over abundance of condensation on the dipstick.

I have tried, straight venting (pcv main hose disconnected from intake pipe)

The JAZ catch can, plumbed inline with the intake hose and also just straight venting.

And I have tried a regular catch can with one side vented and the other side to the PCV main hose.

Anyone have any ideas?

But people have run it with out, and I haven't seen complaints of excessive condensation.

stuff, even when I run the catch can inline with the PCV main hose to the intake, (meaning, I retain the stock setup completely and add in the CC) I still get condensation.

I have a new intake pipe, and a K24 on the car. The stock intake pipe no longer fits properly. I also went with a 2.75" aluminum J-Bend in place of it. At this point in time I do not plan to recirc. the pcv back into the intake.

That also wasn't my question ;-)

I see. My apologies.

As mentioned above you will need some sort of vacuum.

I'm asking the people who run theirs open vent, why they don't get condensation.

I know in theory you need some vacuum... but there are people who run their cans venting.

Ive read that someone wrapped the dipstick tube with some insulation. Due to the car driving down the road and the hot oil and the cooler breeze going over it, it can cause condensation no matter what..

Interesting...

I'm a newbie here but here goes, do you mean condensation in the oil itself or just within the dipstick tube?

If it's just noticeable in the tube you should upgrade to the dipstick with 2 gaskets. Maybe even make something that seals down lower in the dipstick tube so there isn't anything to condensate on. Phil could be right about the cooling aspect while driving down the road, but then again if you have a bad seal that might be your only problem.

I have to replace the dipstick tube in my girlfriends 98 VR. Cleaned it out once but after a few months with lots of rain/snow there is some crap/condensation noticeable. 3k oil changes, and a pcv due too so there is 0 neg pressure.

I'd agree with this - get the new style dipstick & replace the base seal while you're at it.

Venting to atmosphere or not, would not cause condensate in the dipstick.

Hmmm... does the end of the new style dipstick look the same as the old one? I think I have a new style here (brand new). But originally I was convinced that its the wrong part because it is completely different.

I shall have to try it out..
