Metco Breather Question I'm sold on getting this to replace my oil cap to relieve pressure. My question is that enough? Do they make one to replace the trasmission fluid cap also? What is the part # and is there another place to get it besides Thunder Racing (I've looked through the other sponsors already).

The question you need to be asking is why is there more pressure in the crankcase than the PCV system can evacuate. Breather filters are not meant to relieve pressure. If they were, they would not be a filter. They are meant to filter air entering the crankcase that the PCV system is drawing out.

Oh, I just read from another post that it is reason that he got the breather. Is that PVC thingy on camaro 98-02? Should I just replace the PVC? I think I saw a write up somewhere...

The filter is to keep the damn oil particles in the vapor from getting all in your engine compartment. I think breathers are awesome by the way you pop the engine and you get a little bit of steam rumblin out of it pretty cool, but I may be a loser hahaha. Thanks

Actually he is right on. Air CAN go both in and out of the filter, depending on the pressure in the crankcase, which changes with outside temp, engine temp, and RPM's. The the PCV system is going, air in entering the crankcase through the breather filter which means for cleaner air in the crankcase. Not really a necessary thing if you ask me, if you have some extra bucks its not a bad thing to have, but the money could be used for something better.

The only time i saw steam coming out of my breather was when i was having a major blowby issue due the blower cracking and breaking mt ringlands on my stock pistons. The only reason im running a breather is i got rid of the stock PCV system.... and my breathers on the drivers side.........

allot of the FI guys are having that problem! I have changed my PCV sytem twice and still have problems so I got the Metco breather and the oil in the valve covers would make it up to the filter then oil would drip on the exhaust manifold. So I used the Metco billet adapter a Moroso EVAC system where the exhaust backpressor sucks the extra air out! worked great!
