my style oil spearator by arb on 28 Apr, 2010 10:52

Here is the all aluminum oil separator I made for my 1984 NA 1.6L I turbo'd and put in my Dodge Caravan (build in a different thread).
I started with the cheap 2" x 1/8" extruded aluminum sold at Home Depot. It has some coating on it that does not TIG weld well, so a quick cleanup in the bead blaster worked well. Here is a view of the four sides after they are welded together and the top vent tube is welded in place for a 3/4" hose.
Here is half of the bottom, with the 3/4" fitting for the hose from the valve cover.
Here is the bottom, both halves being welded to the bottom,
Here are the baffles I made from the same stock. The holes are about 3/16" and you'll see there are several layers of them.
Stacking them in the bottom.
Above the baffles I put a 3/4" thick vapor canister filter. It was round but I cut is square. Its for a 1993 GMC Sonoma 4.3L - oreillyauto.com Auto calls it "BWD - Vapor Canister Filter
Part Number: EC224"
Here is the top - I welded a couple of bars across the ends of the top and drilled a tapped 1/4" x 20 holes in each corner. The top is sealed with engine RTV and stainless steel bolts are holding it in place, with RTV as a lock tite.
Pained for extra sealing of any pin holes.
Mounted to the firewall.

Looks nice! Hey I wanna talk to you by phone about setting up my TIG. Do you have time for that?

Arb I have much respect for your "can do" attitude, I think, given enough time you could build the whole vehicle from scratch
. The separator is a really good idea, no matter what the Alpha dog says ,. Also your use of commonly available material is really 
, your whole project shows what can be done with some ingenuity and a desire to make it work, kudos.

The oil separator is definitely a good idea. I'd be more inclined to install a TD valve cover and the stock oil separator, but I know you like your stuff homemade from scratch, Arb.
Yeah, I like just knowing I have something unique :-D I actually tried to get a stock baffle, but the guy never followed through. -

You could still add the cam baffle, TD valve cover and TD oil separator and then run to your separator. Sure wouldn't hurt anything.
It I can find them, I'd like to change to that :-)
