New Catch Can upgrade

[XfireZ51]

The WGF 1/2 mile was a fun event. unfortunately, I did only one run.
On the way to a second run, we noticed OIL from the motor which later turned out to be an Oil Pressure Sending Unit located on the passenger side of the motor in a "godforsaken spot" not accessible by humans. So I went to see Mr. Polatsidis for super Human hands. I'm sure it's a talent developed from "working" w farm animals for so many years.
Anyway, I decided to install a more "proper" catch can instead of the chincy LS-1
type I bought off eBay. I don't have the AIR pump so that spot turns out to be a good location for the catch can. Actually it's an Air Oil Separator. No baffles or steel wool accumulator.

Voila!

Looks like a good spot. Mine is a Moroso (to be installed). And, I have been eying that spot too.

I like the in/out arrangement of your unit. The Moroso is more of a "T" configuration. It is going to require some extra adaptation so in and out are from one direction like your unit.



Say! What is that do-dad on the upper left edge of the photo, the one with the red and black wires???

Paul,

This is what the catch can looks like



Took just a bit of proper fitting but it works. The one thing about the placement is any interference w the headlight mechanism as it swings on/off. Need to position the can low enough to be out of the way. That's why I routed the lines under the frame rail and back up. Actually the D1 is an Air Oil Separator. Does not have baffling or use accumulator material. It relies on oil being heavier than air and dropping out of suspension when it gets to the can. That's also a cooler spots so hot oil cools off traveling thru lines and entering can. There's a sight gauge on the side indicating amount of oil in can helping to decide when to empty it. With the amount of oil I saw under the passenger side IH, I thought it was time to upgrade and suspected part of the problem was crankcase ventilation. One thing I did do w this unit was to make a gasket for the top. Didn't trust the white sealer they had on there, and the last thing I want is a huge vacuum leak. So gasket material and a bit of Permatex 2A.
And yes, it was the oil pressure unit on passenger side. When Pete pulled the connector, oil came streaming out. On his lift, we had a chance to TRY cleaning the undercarriage. Still some drips even now however.

The black/red wiring you see lead to a ballast for my HID fog lights.

Dyno,

I had my previous can in that spot but it was pretty small. With a 92, you have the ASR unit to contend with.

Yep...I am aware of that.......I only have 90s and a 91.

I also moved the main cable cluster going forward on drivers side under the Top A-Arm which cleans up the area above the Top A-Arm and gives more room in that area.

I built mine and placed two on both sides of the frame. Works like a charm, it is baffled and filtered. No more oil into the intake.

How & why are you using two catch cans?

[LGAFF]

There is actually a spot on the inner fender to mount the cans with the existing screws and holes

Volume for the crank case. When you are WOT there is no vacuum pulling vapors out of the crank case. Two Catch Cans prevents over pressurization that can force oil into the intake.
One can is probably fine, I was going for over kill and it was R&D for me.
