Venting a Moser

[Bow Tie 67]

I have been pumping fluid out the breather at track events. At first I just put a 4" hose on the nipple and it was fine until I really pushed it on the track. I pushed fluid out onto the exhaust, man that stunk, ask SubtleZ28 ( Shaun ) he was right behind me. So then I put on the sintered bronze vent and same thing although not as much.

My question is for a quick fix, until I have more time over the winter, whats the best type of filter to use so I don't loose fluid? or is it more of a matter of placing it high enough? I also thought of plugging it and moving it closer to the center section so I don't have the g's pushing it all to the vented side during long hard sweeping turns.

Thanks,
Matt

I just used low budget rubber fuel hose to a clear plastic fuel filter fastened to the body above the rear axle area.

I had to end up switching over to a 1/4 nipple and a hose up to a K+N. So far so good.

Here is a pic of mine. Am I doing something wrong. If you are not four wheeling your pro tour car why do you need to vent much higher than this?

[Vegas69]

That will leak like a siv. Already tried a similar setup.

It will "vent" fine. But you'll have gear fluid everywhere.

Leak oil out or water in?

Read the previous post from John.

Mine is fine until I pull high G's cornering. It's amazing how much fluid pumps out and the mess it makes. I'll be making a permanent solution over the winter, most likely with AN hardware.

i have had no trouble with mine, however i am with matt, i will be using a pipe thread to an#4 and run line up to frame rail and mount a small k/n style filter

That's very similar to what I'm doing. I use 6 AN, but that's probably excessive.

probably excessive.

John,

Say it an't so, not on your car!!! LOL

A larger hose might help if you have problems with fluid being pushed up the hose. To small and there's no room for the air to get past the oil. A -12 line will work, but will be way overkill.

You seem to be implying I've gone overboard in other areas on the car, lol!

On Power Tour, improper venting + overfilling led to a blown axle seal. At RTH2, my LR brake assembly was covered with gear oil--pad and all because ran a vent hose to the frame rail as per Moser's recommendation, but..I aimed the vent hose right at the brake assm. I just never thought it would puke. Oops! Brain on: Now I have a barb with a 6" piece of hose that goes up to a 180 degree bend then straight back down aimed at the floor. A Zip tie controls it's 180 degree shape. Rear is filled with the car completely level to avoid overfilling.

1/4 npt to 12an is probably impossible without 12 adapters. 3/8 hose and the filter above and as far away from the rear end as possible.

Steve,

That will most likely puke also:

I added a piece of tubing about 4" with a fuel filter as a temp fix. The pics show first installed and some oil in the filter with a fine layer of oil on everything after racing it. I don't believe enough pressure was present to make a mess at the auto-x. But add high sustained g's, 4.10's and high rpm and it made it past the filter enough to spray the undercarriage and drip from various compnents.

Now I'm wondering if -6 will be better for drain back or worse for oil pressure release? I want to run a AN hardline to the center of the diff then a flexable hose to a K & N mounted to the DSE shock tunnel.

I run 1/4" NPT to 6 AN. From there to a low-profile 6 AN 90 fitting (to keep the line out of the exhaust at full suspension compression) to 18" of flex hose to a bulkhead fitting into the trunk. From there I go hardline to another bulkhead fitting on the outside of the frame rail behind the rear tire in a little protected area. I hang a K&N crankcase filter from there.

No puking at Pocono, Road Atlanta, RTH3 or RTH4 and no blown axle seals either.

you guys need to install these, and be done with all this leaky stinky gear oil mess's, bottom right page 18
