Hi all,

q.1. heavy hitters how did you deal with evap / charcoal canister?

q.2. heavy hitters how did you deal with your PCV?

Just finished up the monoblade install.
the AS&M monoblade does not support evap / ccp and PCV.

*I have ideas but I'am looking at all the options.cwm7
**if you not a heavy hitter feel free to jump in,
just keep in mind were not talking about pcv / evap for stock LT1s

I'm conisdering running the grand nat LT1 air pump PCVacuum setup.

When you are saying PCV , are you speaking of the fresh air side side from rocker cover to TB? Is so can't you just just get a line in between TB and MAF?
Other side, which I don't subscribe too , filters in rocker covers.

If Vacuum side and this is because IAC passages are cut away you should still be able to use the PCV port at the front.
Or go into the side of the Intake like earlier LT1s. There is a passage there to the IAC passages.

Evap, being it is PCM controlled, I see no reason you couldn't hook it to the plenum.

I don't know if it's that bad to just fore go the fresh air supply. Perhaps you could just let the PCV suck on the crank case and see how that works before fussing with it. Or is it required for emissions?

I'm not exactly sure how the evap. works. Does it pressurize or put a vacuum on the tank? Whichever, it's generally safe to listen to Gerry.

Where the steel fuel tank vent tube ends just under the upper control arm, I have it capped with a filter (so the tank is vented)and everything else associated with evap disconnected. No breathers in the valve covers with a 4 vane moroso vacuum pump that pulls 12 in. Zero, and I mean zero oil leak anywhere.

Mike, I think I'll give this a try.
If I don't like it I'll go back.

I'm goning to try a moded LT-1 air pump.
early tests show about 4"hg with a single pump.
and its a free mod since it is laying around with mounting bracket and wiring.
