Okay! That is noted, would the old (new) LIM gaskets be reusable?

The gaskets we just put in should be fine. They are a hard plastic frame with a thicker rubber seal. The gasket is not crushed. So inspect them good. They've only been in a few weeks.

you didn't use the aluminum ones?????

Yes, aluminum gaskets, inspect the rubber seal, the aluminum is the frame inside the rubber.

Okay lol, you said plastic first.

Ya I did, sorry about that.

Hey guys.. I've dealt with a lot of ZZP PCVless stuff. That'* the reason I mentioned to Tom that even putting in the groove they suggest, he'll still want a breather.

The truth behind the PCV is this..that valve is only there to vent crankcase pressure/gasses and allow them to flow back into the TB and be reburned. Therefore if you vent them via a breather, there is absolutely no reason to add the groove. The groove BTW is so small and pathetic I wouldn't trust it to vent properly on a stock engine. ZZP missed the boat on that one IMO. They used to say use a breather as did Intense, WBS is the only place that built the pcv functionality into the core TMK. And the holes are the same size as the factory holes..not a nickel sized hole full of gas being expected to fit through a small groove that will be half filled by the gasket.

If this was my engine/car, and I wanted PCV functionallity, I'd get another valve cover cap and drill it. Put a grommet in the center to put a pcv into, then run a line from that to the TB and T the fitting where the evap is hooked up. Presto..same thing. Many W body guys do this on both front and rear covers. Except they drill into their valve covers.

As for doing the fuel lines.. I can't see how tearing off the LIM would be any easier. The lines on the 2000'* are in a great spot compared to the 92-99'*. Makes me wish I had an 00+ some days.

I would think that by opening up the PCV system, even if it'* not enough to vent all the gases, would mean you have that much less gas flowing through the crankcase with your oil until it makes it to the breather. Or that it would reduce the amount of time it spends in there mixing with the oil. Am I completely off here? I still have a very basic understanding of how this works. I plan on running the breather regardless like you said.

I also found some interesting information online.

"Disabling or disconnecting the PCV system can also allow moisture to accumulate in the crankcase, which will reduce oil life and promote the formation of engine-damaging sludge."

This is what I am getting now with the breather, and it could very well just be gunk still in my system, but I'm not sure yet.

"Because the PCV system pulls air and blowby gases into the intake manifold, it has the same effect on the air/fuel mixture as a vacuum leak. This is compensated for by the calibration of the carburetor or fuel injection system. Consequently, the PCV system has no net effect on fuel economy, emissions or engine performance -- provided everything is working correctly. "

If everything above is true, then the only real reason for me to open up the PCV system would be to get rid of the moisture and sludge that is accumulating, assuming it continues to accumulate.

BTW, thanks for your help and insight guys, I'm trying to get to the bottom of this whole issue and see what it is really doing for me.

I don't think Dan was suggesting that taking the LIM off would help with the fuel lines, only the SC. I saw him struggle with those lines for a while because he put the SC on before the fuel rails. I plan on changing the lines running between the fuel rails as well, they kinked up a bit.

You are correct, you need the LIM installed to put the fuel rails on anyways. The rails mount to the LIM. After the rails are in place and tight, you can put the S2 in place, then the supercharger.

On the PCV.. I'm going to go back a little and correct myself.

I originally said you'd be causing a vacuum leak by adding the breather. However the reality is...this only happens if the pcv is functioning and you add a breather. Because then the pcv (slightly under vacuum from the intake) can pull air in through the breather into the crankase and into the intake. Aka vacuum leak.

In your case th pcv is fully blocked which keeps any additional unmetered air from being pulled in. Therefore you had some crankcase pressure to be vented and your breather is doing that.

I run a breather and have since I could. A good friend and well known modder suggested to me that even with a full pcv funtioning that at least one breather on a valve cover would be good as the pcv may not vent all the pressure quick enough, therefore you run the breather and your LIM and valve cover gaskets don't become pressure areas and blow out.

In running a breather for over 2 years now..My oil may get dirty a little faster (or it'* my driving style ) but it'* never gotten milky/gunky like yours. I'm thinking if you do a coolant pressure test that you may find there is a leak somewhere. Or you don't drive a good 20 minutes etc often enough for your car to get up to temp and burn off any condensation.
