PVC Install Question

[classical glass]

Hi Guys,I want to install a PVC set up on my 2- 4 barrel side oiler. My questions are I would like to install a catch can with this setup and can I drain the catch can back to the oil pan? I recently installed a Aviaid 10 qt oil pan with provisions welded in the top for 3/8 and 1/2 hoses. They are blocked off now but are easily removable. Another question is where is the best location for the vacuum source (base of one of the carbs)? There is a bolt on plate at the rear of the engine that looks like a draft tube would go there. Could the PCV valve be installed there instead of the valve cover? I hate to drill into my new Cobra valve covers. Finally there are so many PVC Valves is there any particular one I should consider?
Thanks for your time.

Sounds kind of like a solution in need of a problem. Unless you have reason to believe otherwise, I suspect in a properly vented system you're just not going to get much, I sure don't nor do several I know of. Mine vents to the carb vacuum fitting from the intake mounted valve and I get little or no vapor.

I would not to be too concerned about running a line from a catch can back to the oil pan to return any oil. There should not be that much oil venting into catch can. If there is a copious amount, then you should have the engine looked at.

The FE with dual quads has that plate retained by two screws that can be replaced by a PCV system. You need to go boneyarding for a 62-64 big Ford/Mercury FE to get the system. They use an EV-1 PCV valve that threads into the plate.

If your area doesn't require the use of a PCV valve for emissions, don't run one....

Your comment got me thinking, is there not some thought a PCV may help with a potential rear main seal leak in an FE based motor keeping pressure down a bit?

[blykins]

As long as pressure is vented, there shouldn't be anything to cause seal leaks.

PCV valves can cause a lot of problems: 1. It's difficult to find a PCV valve for every engine combination 2. If guys don't stay on top of things, you end up pulling oil down into the intake manifold, which causes oil consumption.

Thank you, I guess I learned something today I was never really sure about.

I installed one of these on my 514. M/E Wagner Performance Products – High Performance Crankcase Ventilation Systems.
