if this stang has long tube headers there may be a spot on the headers just before the collectors for this hose to evacuate the crankcase.

rdrunnr With the Vortech you are supposed to remove the line that goes from the filler neck to the throttle body and use a breather on the valve cover instead of an oil cap to help it vent. There may be a little oil that blows out of the breather, but stuffing it with a little steel wool will fix that.

Thanks

Damm, that was a quick response; thanks!

I'd go with the suggestion like you already have and rig an overflow can (like a radiator overflow can) to catch to oil.
I'm not sure why the say to put it near the air filter. I think it may be that the end of that hose needs to be at a certain height compared to the motor, but then again maybe they just wanted to hide it so they stuck it in the fenderwell.
Hope that helps, and thanks for the good words, i'm glad you enjoy the site.

Vent hose from Valve cover??????

I have a 1993 331 stroker, EFI, water/meth injection, Vortech supercharger in a 1965 Mustang Fastback; brand new motor (500 RWHP). The hose coming from the valve cover comes down, through a hole in the front fender and next to my Air Filter (Air filter located in the fender well).

I always noticed drops of motor oil on the ground under the air filter. The oil is coming from this vent hose from valve cover. I was told that this vent vents pressure from the crank case when the engine is under BOOST, and that the vented air needs to be sucked back in the engine (why I don't know). So I jury rigged a plastic bottle over the end of the hose to catch the oil.

I was told to rig a "Catch can/bottle" under the car some how, rig this vent hose into the can, then another hose from the can to the airfilter. And install a petcock valve in the can/bottle to drain excess oil.

I've driven the car for 600 miles with MY jury rigged set up and no problems. I'm just wondering, is there a reason for this hose to be so close to the air filter, if it is simply a vent?

Thanks,
Mike
