Doing away with pcv ?

[91CoupeMike]

Ok for the last time hopefully..

I decided that I didn't want pcv after I pulled my intake and the ports were all oily and dirty from blow by ect.. I also don't have a way to run a vent to a metered source without drilling into my power pipe. So I just did away with it, smokes a little but it goes away.

Anything I should consider or reconsider ?

why not run a catchcan set up?

I guess I could. But wouldn't I still need a vent off of my valve cover?

The way it was before and when it was tuned, there was a lot of vacuum at idle on the crank case, you could take off the oil cap and hear it suck air. I didn't like that because any leak could turn into unmetered air.

If you have blowby, you are going to blow out seals and be leaking oil all over the place, and maybe even worse if you dont have some sort of vacuum in the case. If you dont like the oil in the intake, get a catch can.

I tried to run w/o a pcv and the boost would get past the rings and into my crankcase, which would force oil out of my dipstick and make a mess. If you could use a filter in the pcv line, it would help.

Good to know I was wondering if it would blow seals out and I did notice oil coming from my dip stick and getting on my plug wires.

The problem I'm having is the hose on the valve cover that normally goes to the throttle blade. My race accufab doesn't have the port for it. Any other solutions besides putting a hole in my intake tube and getting my $400 throttle body coated in oil?

Freshen the motor up to alleviate the blow by issue, however there will always be some residual blow by since the rings don't seal 100% to the cylinder walls. Also the rotating mass creates positive pressure inside the crankcase, thus requiring a way to vent or relieve itself. Hence the reason they make the crank evac setups.

As said above, if the residue is your main worry and gripe, use an oil separator between the pcv line and the vacuum source, and you can install one between the valve cover vent and your nipple you install into the power pipe.

While I see intakes that have a heavy coating of oil from the pcv and crank vent setups in cars I work on, the bad cases are usually all high mileage or severely neglected. They suffer from heavy blow by, most vehicles in good working order don't produce a lot of residual oil. Baffles in the valve covers help to also greatly reduce the amount of accumulation. I assume if you're running stock covers still that the baffles are in place.

[91CoupeMike]

Stock valve covers but I had to remove the baffle to clear my rocker arm studs.

Guess I'll make a port on the bottom side of the power pipe.

Dang it!

Oil residue doesn't bother me as much as I just like to have my stuff clean. I spend more time cleaning parts when I work on then I do the work itself..

This is what I'll be doing to my car to do away with PVC system. Best option in my opinion

[91CoupeMike]

I thought about that, but it would require me to get different valve covers and tap into my headers.

I've heard that kit will also ruin your catalytic converters if you're still running them.

No doubt and no that was the second modification to my car lol

[Blackpony]

What I did on my car was run a 5/8 hose from each valve cover to a catch can with a filter on top. Never once had a problem with excessive pressure or oil leaks

[majorownage]

Why all the fretting?

There is no power gain from running any sorta evap plumbing, so why not just have it vent to atmosphere and forget about it?
