Hey all I have I 428 Windsor in my 70 Mustang I've been getting a little bit of oil out of the breathers. I don't want a mess on my motor or under the hood. So I am thinking about doing a breather oil tank. I wanted to know what tanks you all recommend what size line and where I should weld my fittings on my valve covers. Thanks for the help

I installed a Moroso air-oil separator connected to a pvc-valve on one side (breather on the other) and ran it in to the intake manifold. Stopped oil coming out of the breather and collects all the nasty blow-by.

Check out page 26, post numbers 254 and 255 in my build thread, link is in my signature. The tank is made by Allstar, and I believe I bought it at Summit. Came with bracket and filter. The line size is -10.

So did you do 2 tanks or is there a crossover? It looks good what size line did you use?

1 tank off of passenger side valve cover. No crossover, and line size is a -10, which is almost 5/8" ID.

So the driver side valve cover has no breather in it?

No. No need to vent both sides with a line this big. This is a street car.
I raced asphalt late models that turned 7500 all night with one vent on drivers side.

Here's a good read about different types of crankcase ventilation systems:

It explains why factory systems are not quite adequate for higher performance driving situations and provides examples of different levels of CCV systems.
