Catch Cans - Ideas

[royster]

I'm glad this topic took off, because there's lots of great information here from people who know. As an added bonus, we get to learn about the charcoal canister.

My original thought for the catch can idea was to prevent excessive oil beads and blow-by from getting sucked into the engine and contributing to visible smoke...probably a "sky is falling" view on my part, but without facts, the human mind creates some unreasonable stuff and considers it possible.

From what I've been given on this thread, the standard system I have is good enough for stock performance. (An inspection of the PCV lines revealed no excessive oil sucking). Having spent a good amount of time cleaning out the plenium, my "fears" seemed justified. Then again, I corrected the original problem, so that shouldn't be a problem anymore. It was a concern that the PCV line is a down-hill, short shot into the plenium.

There's also a good chance the engine is still burning off Seafoam and residual oil from the exhaust system. After I run the vehicle on the road for a while, I'll have a better idea what's going on (or the problem will disappear).

Meanwhile, many thanks for the input from members who know.

You mush have a closed system or you will fail smog. Use of one of the items above will fail your test.

California smog is mid evil to say the least lol. However, the bottom pic I posted is for re-circulation style systems (closed). All it does is filter the crank waste, and send the air back in. Many of our California clients use this system exactly for that reason and none of them have reported a failure because of it. The atmospheric type (with the filter on top) will fail a California smog right off the get go.

Hey Merrill on those catch cans your selling with the material inside, what is the material (filtering product) that is contained in the canister?
Also I would imagine that the material is replaceable so when it gets clogged with collection of the crank case stuff. (if I'm correct)

Gravity is the filter. The baffling and chambers of our system allow gravity to do its job (separate the crank waste from the air). There is a ton of R&D, engineering and live product testing that went in to these. They took over a year to develop. The main reason they took so long is they are a sealed, lifetime use product that never needs filter of baffling to be replaced. You simply wash them out during normal service intervals. You can use products such as brake parts cleaner, de-greaser, detergent, or just tip it over to dump the crank waste out. If the baffling ever does fail for whatever reason, it is covered under warranty.


The other part of this is the factory ventilation system. Yes many systems will line the intake manifold and CC's with gunk. They technically were meant to do that. The combatant to that problem is regularly scheduled maintenance. Catch cans are primarily for performance engines. Relieving excessive crank pressure is a modification that produces results (like installing a cold air intake is a modification). Unfortunately it also produces excessive crank waste (oil and moisture). Many race engines remove their baffling which allows more airborne crank waste to escape. The last thing you want to do is send all that crap back into the engine - especially an engine with a lot of performance mods. The catch can is the solution to the problem.
