ok dammit i guess new covers in order too. anyone need some tall dart valve covers with silver vein powder coat? lol or does anyone have some fabbed covers tall with no holes?
 
Engine must be sealed complete. No breathers, no oil dipstick tube, no cheap THIN sheet metal covers, ect. If your adding a vaccume pump to a engine that was built without that in mind, your not gonna notice much at all. You have to prep your pistons/rings, specific ring thickness, and specific ring material differently, in order to take advantage and notice any real gains with a vaccume pump. If you didn't have the engine built with all this taken into account, just put a $60 crankcase evac. kit on from Moroso. It will deffinitly help.
 
damm really wtf well i ran my engine for about 10 mins and after like 6-8 mins i had oil dripping out of my k&n oil breathers i was like damm i better get a vacum pump. i didnt know all that shit was involved.
 
You can use those valve covers.
On one side you can install a -12 bulkhead fitting for the pump vacuum
and the other side the regulator.

You can put one on. Just don't expect anything to happen other then stopping oil leaks. That's why I say use the Moroso evac kit. It's like $60 and will get rid of oil leaks and help pull crankcase pressure. When i put those evac kits on cars, everyone idles cleaner, revs up smoother and stops all oils leaks from excessive pressure. I'd be happy to help if you choose to go that direction.
 
only problem with the evac kit is you'll have to mess up the pretty coating on the headers have to weld in the bung for the evac kit.. just keep those covers and run the pump on one side and the regulator on the other.

They normally say with a vacuum pump using the relief not to put it on other side of the engine. To have it inline between pump and engine that way it won't pull moisture through the motor.

Yes it will. It's either do it that way, or spend hundreds and hundreds on a pump only to have the same result.
