My KLZE Festiva Build Thread

[skimsucka]

I have 3 to build, I don't wanna hear it

I thought only 2 left ?

[Flyin4stroke]

^x2. Hopefully I can bribe people to give me money for my b-day so it will pay for gas.

Oh I know my car will be driving by FM6, I just don't know if my bank account will be ready for FM6

^^then explain why when I disconnected the can from the turbo.... Meaning no extra vacuum in the can.... The can sprayed oil all over my engine bay, literally like a friggin garden hose

That would be excessive blowby. I didn't catch that part.

When things are located properly and the engine is in good order (i.e. no excessive blowby) the catch can will work great under a vacuum. Engines make more power with their crank case under vacuum.

Yes, yes it does, but those systems also utilize catch systems with vents (the ones I've seen) or vent directly to atmosphere via the vacuum pump outlet instead of venting oil mist back into the intake stream. The latter leaves oil buildup under the hood unless a vent tube is installed to direct it.

The only system I know of in OEM configuration that doesn't rely on crankcase pressure is on older Honda (granted, I don't have a lot of specific information about PCV systems). They use a venturi duct in the intake stream that induces vacuum under load, actually pulling the gasses through the tube instead of them being deposited there as is typical.

Most aftermarket CAI's or SR's don't have the same type of venturi duct in them, so the PCV system doesn't operate as it was intended when those things are added to that type of engine.

I have a half-backside redneck mod idea to use a AIR pump (which is not positive displacement) to vacuum the block. I'm not sure if they'll pull enough CFM to be effective, though. I've heard that you don't want to exceed a few inches of vacuum so you don't pull the seals in, but I don't really see that actually happening, considering the shape of seals.

Current state.... Hoping to fire it up tonight

Don't worry you aren't the only one with an engine swap to do before madness. Cutting it close this yr.

There are a bunch of us cutting it close. Had to swap into a GTX bottom end.


And a taller 5th gear

I think your catch can might not have worked because there's no breather on it. Afaik, that's necessary, otherwise the turbo is putting vacuum in the motor, sucking the oil out and baffles won't stop it. The PCV system works under mild pressure, it wasn't designed to work properly with high crankcase pressure or under vacuum.

Your catch can with an extra tube and a filter on the turbo side of the baffle should work properly.

I'm workin on my motor swap as well before madness haha

I have one also to do with a wire tuck.

Thanks, hopefully once the new motor is in, it'll be better and more powerful then before :evil4:

This is the natural progression of things. I swear every bp i've replaced has been stronger than the last.

cya at FM6.

Sorry to hear that Chris.. major bummer
