ok so i know that i need some breathers with the pvc valve in them but where do i connect the hoses that are going to be coming off of them. i thought about in the back of the intake where i have my power brakes hooked up, but i thought that the purpose of this was to get the air out of the motor. so if i hook it back up to intake wouldnt that just put in back into the intake air??? would a vavum pump be overkill for something like this. something like a moroso one ??? i kwow that race cars with no exhuast put it in the collector but i do run exhasut sometimes. it is a half *** exhaust just to make the car street worthy the very very little i do go out in it. i also know that this will stop the oil from blowing all over everything when i do run it. any help will be great.

 

Well your out and in theory with the air is kinda right. You want to eliminate pressure out of the bottom of the block (crank case area/under piston area) so your motor is not working against itself. With all the holes for the oil drian back the simplest solution to get the air out is like you said with either a crank case evac system so it takes any pressure build up and "puffs" it out the exhaust system and out of the engine. But the only draw back I've found speaking from experience, is that trying to run a evac system that utilizes exhausts negative pressure is that when you have the mufflers installed it creates enough back pressure it will actually suck in and blow out with the pulses of the engine. When I removed my mufflers then the evac worked fine putting a little bit of suction in the lines...not alot mind you, but any little bit helps.

3 options come to mind from cheapest to high dollar:

1. get rid of the PVC idea and just install 1 or 2 breathers PER valve cover. I ended up running 2 K&N breather filters per vlave cover and it stopped my dipstick gysert that used to shoot up and out and covering everything under the hood iwth oil.

2. An electric vacuum pump, stories with these are 50/50. Half the guys say it works great, the other half say it does'nt pull enough vacuum...but they're trying to compare suction to a belt driven vac pump for racing and making higher hp numbers so IMO it's not an apples to apples comparision. If all your wanting to do is stop blow by-get the electric vacuum pump, put a fitting on your valve cover, run a hose from the valve cover fitting to a vented breather tank that will catch excess oil vapor sucked up by the vac pump, then run a line from the breather tank to the vac pump. This will ultimately help for what your doing and be under $200 if you shop around.

3. Since it's mostly race and rarely street, the $7-800 vacuum pump set-up is also a great option and a good long term investment, it will serve the purpose right now and then wwhen you build your new motor you can build it loose to take advantage of the high amount of vacuum this pump will provide and get a few more ponies from your engine.
