Going Around The PCV Valve
Can you go with out the valve? like take it off and plug the hose then install a crankcase breather in the hole where the valve was?
I heard that the pcv valve has a little problem of letting oil and other junk thru. which make TB and what not real nasty. just looking to see if there was a way around it.

some have installed oil separators on the line, I think its in the lightning forum. I believe the general consensus is , that this seems to fix 90-95% of the problem, for 15-30 bucks...

I may be wrong but if you do this you are allowing unmetered air to enter which will cause your engine to run lean. Guys that have done this mod. also have a custom tune to compensate. I would do some more searching to find out.

Lago,
I don't think that will allow unmetered air into the engine. The reason for the PCV valve is to suck out the crank case fumes and burn them in the cumbustion chamber. If you install the filter in the PCV valve hole all that will happen is that the crank case fumes will escape to atmosphere.
kievitk,
The valve is on the passenger side cover. What are your plans for the driver side? It doesn't have a valve but it does the same thing. I used an air line filter to trap oil from the PCV valve side.

JMC,
I thought I read in a post by Neal, and I can't seem to find it at the moment, that he had to have adjustments made to his A/F in his custom tune when he did this type of mod. to his truck. Maybe I misunderstood what he did?

The reason for the PCV system is to vent the crankcase of the blowby gasses. If you don't have some sort of vacuum to suck out these gasses then you will have acids forming inside the engine as well dilution of the engine oil. I would recommend an oil seperator in the PCV valve side of the system to keep oil out of the intake.
