General Information

Here's the Jaz Products mini-breather can.
Was in service, removed during ModFest2003.

PCV Breather Can Setup

Most Recent Setup:
Removed during ModFest2003 for sealed-system implementation.

Jazz can installed on shock tower.

View of cam cover hoses.
The hoses were what I had available at the time.
It'll get it all cleaned up, once the -ideal- catch can goes in, LOL.

Front view of the hose route.

Side view of hoses installed on cam covers. Note the cap on the throttle body port. No need for oil-laden vapor to go in there. The -ideal- catch can will re-route specifically to the pre-turbo intake pipe. The sealed system necessary to comply with emissions regulations will be preserved.

Previous Breather Can Setup

This is the previous setup, the 1st alternative to the sealed OEM routing. Using a reversed PCV pipe from the NA 7M-GE motor, a single hose run to the Jazz can was accomplished. The 2ndary port on the Jazz can was plugged with a vinyl cap. Besides being a stinky solution that would be ill-advised at all, the flow from the cam covers was found to be quite prodigous. I felt separate hoses to be an immediate need, so as not to needlessly blow out oil seals in hard-to-get-to places. This is especially ill-advised on a tired motor. A sealed system was deemed a "must" from this 1st attempt.

The Ideal PCV Catch Can

This whole idea of separating hot oil vapors from the crankcase blowby, then recirculating to the intake for re-combustion has really consumed more time than it's worth, LOL. The final version will not look like any of the below, but definitely will include Aeroquip 250psi-rated cloth-braided hose. They will attach to push-on AN fittings, with -08AN on the cam cover side, & -10AN on the intake side. Aside from the transmission lines, the tank remains open to suggestion, as long as a heavy dose of internal heatsinking/baffling is part of the process.

The object will be to cool, & condense the hot vapors into tank sludge fit for the recycling tank. The obvious benefit of not passing that goo back through the turbo, & intake will not be analyzed here; however, from an emissions standpoint, retention of the closed-system preserves the factory PCV function, which should pass muster during a visual inspection of the car's smog check-up. Your results may vary, since brain-dead smog test techs are numerous. Find a tech who understands that performance enhancements help the environment, too.

Off-soap-box.

Too much thinking to do on the 4th of July!

Here's a recent version, idea #3 for the perfect  *Sealed*  PCV condensation tank,
drawn up after opening the hood, & having 3 beers:


Inlet's on the side, Outlet's on the top, & drain is at the bottom.
A single internal baffle serves to force vapors downward,
cooling as it passes the conductive aluminum.
No external heatsinks this time 'round.

Here's my 1st, far-from-perfect idea for the perfect  *Sealed*  PCV condensation tank:
