Also had oil seeping out of the breathers where they're pressed together. If your going to use the Moroso breather with the electric pump , you will want to JB weld the area where they are pressed together . And around the nipple . You will also want to seal the other valve cover when running the electric pump . If everything is sealed up right it should sound like this : http://s151.photobucket.com/albums/s152/cedoz/?action=view¤t=vacuum-Clip002.flv when I shut the motor down it had pressure in the crankcase. I'm guessing it's working the wrong way. Check balls are probably bad . I had the same problem running the Moroso set up . |

I did some experimenting w/ stock ford smog pumps a while ago. My old combo was being shifted at 7500 and I paid no mind to pump speed. Pump worked great, just ran it too fast. I'm trying a pump from an 80s Escort now, w/a Moroso pulley to slow it down. The GZ Motorsport pumps are reworked Ford ones w/ vanes that are oil resistant. I made up the brackets from crap I had laying around:   |

Don't think I'm going to find a cobra in a local yard, need some more info on the Lincolns:) That's something I can test right there in the yard with my little battery. Jesse |

I had the same problem running the Moroso set up . Breathers just have something that looks like wadded up stainless mesh in the top and the bottom has what looks like a separator. Would the check ball be in the part that screws into the downpipe? I might try pulling it off and hooking the tube to the downpipe directly until I can come across another check valve. That piece is hard to blow thru going either direction. |

Check balls are in the part at the down pipe . If there is no check ball , or if they are hooked up without them , it will pressurize the crank case and you will probably have oil everywhere .  |

^Those check balls blow out all the time. I went through 2 in each header before I made the switch to the electric pump...no issues from then on.

Grrr... Figures something would be wrong with it. I'm getting oil everywhere right now as it is. I might drop by the 2nd hand shop again and see if I can pick me up another one for $5. Sould it freely flow in 1 direction when you blow into it? This one would barely flow 1 way but I had to blow pretty damn hard to get the air to move.

Thanks for the tip. I am going to give an Escort pump a try. It would have to reliably pull more vacuum than an electric pump. |
