The mess under the intake

[kowalski]

interesting catch can. did you just plug the hose on the rubber elbow and make the crank vent go straight into the cup?

yes,

there is no oil in the SPRITE cup, just some water in cold season

While your cleaning everything up...clean up that motor as well .... lol...

gotch ya. I'll probably do this... does it not act up at all? usually with a crankcase leak it gets unhappy...?

no any leaks, the engine is after complete rebuild..

Quick and dirty catch can (read fuel filter) until I find something more appropriate and I relocated the ICV (zip ties FTW!) because BMW's placement was stupid. More importantly, vacuum hoses are within easy reach without having to remove the whole intake.

[romkasponka]

where other end of filter is connected??

but doesn't that catch can with the hose in it basically act the same as a crank case leak, as its the valve cover vent.

yes, but I cant understand your mind

Under the rubber elbow between the air meter to the throttle body where the crankcase ventilation normally ends.

Most in line catch cans are sealed and not usually part of the PCV system. To work they would need to be similar to a water trap in a diesel fuel line. They must be periodically drained.
Where does air enter the crankcase on an M42? It exits from the valve cover to the throttle body?

Its a sealed system. As far as I can tell it doesn't take in fresh air anywhere. It just has an outlet for the blow by gases that get around the piston rings. If there was fresh air coming in, it would act like a vacuum lean and mess with the engine management. The blow by gases have already been burned in the combustion chamber and therefore contain no oxygen. Its a very toxic inert gas.

This is the catch can I use on my volvo. Its a high pressure air filter for pneumatic industrial machinery. Its very effective. Eventually I'll get another one for the BMW.

Lol, that's almost as bad as this:


No need to substitute all sorts of non car gizmos for this as Jegs or Summit carries catch cans for cheap.

Or if you wanna go for the bling: http://cgi.ebay.com/ebaymotors/Oil-Reservoir-Catch-Can-Tank-Mustang-GT-Probe-ZX2-SILVR_W0QQitemZ280113147994QQihZ018QQcategoryZ6778QQrdZ1QQcmdZViewItem

IMO, catch cans are really only needed if you do a lot of track events or drive fast on the highway for extended periods of time on a daily basis. Obviously if you have some sort of forced induction, then it's a must.
