PCV . . . Any point to it ? ? ?

[Red97v6Bird]

Alright I'm pretty sure I know what the PCV valve does. Short version it circulates blow-by gases back into the inake manifold right ?
My question is can I ditch it, just to eliminate one more ugly hose going into the intake manifold?

NOT WORRIED ABOUT EMISSIONS

And would this be something that would have to be tuned out of the PCM?

Thanks for any help Guys

I wouldnt recommend ditching the pcv, if you did your engine would be more prone to premature oil leaks. that would be from the extra pressure in your engine. The PCV can cause other problems too like ive seens engines smoke from them being bad.

What Im planning on doing to ditch the PVC is a catch-can. They sell the kit for the LS1 for about $85 and looks pretty nice.

hmmm that does look pretty good . . . would that be interchangeable with an LT1 or do they make one 4 a LT1?

The PCV is the best system out there to remove harmful gases in the engine. If you don't want to do that, then delete it.

A catch can can't replace the PCV valve. The can can help keep oil out of the intake manifold, which apparently is a problem with the LS1 engines, if its in the vacuum line to the intake manifold. You need the vacuum to pull the harmful blowby gasses out of the crankcase. When the vapor in the crankcase condenses it puts water into your oil, and a few other compounds. They can form acids and attack bearings. The alternative would be a vacuum pump, or an "eductor" system that uses the velocity in the exhaust system to pull a vaccum on the crankcase. But those options will not do away with another "ugly hose".

50 years ago the engines had "draft tubes" connected to the crankcase vent system, to use the velocity of the air moving under the car to develop the vacuum, but it wasn't a very "positive" system.

well evidently i didn't know as much as i thought i did . . . .

consider me educated.
