2.2 Oil catch can, more of cleaning up then performance!

Recently I posted in the SS thread about installing an oil catch can , well I found it was a requirement for my 2.2. The OEM hose runs downhill to the throttle body, and gravity takes the oil and condensation into it, yuck!
This ingested oil can
A: clog up your catalytic converter
B: mess up your O2 sensors
C: suck up the oil and you have to add oil every couple of days!
D: make a gummy mess of the intake manifold and the throttle body!

So, I ordered a $20.00 catch can on EBay and installed it on Monday, it sat in my garage for a few of the colder months and it was 45 degrees on Monday so I went to work!
It took all of twenty minutes and had to drill two holes, a couple of pop rivets and hookup the hoses!

I'll keep an eye on this setup and keep you posted, I just hope there's no condensation build up and it freezes up.

The OEM hose slopes downhill


The OEM hose has two bends but isn't enough to thwart gravity!


The long loop hose , was an attempt at fighting Newton's theory



The oil separator catch tank....



Another view , shiny and pretty, we'll see how that stands up to the rest of a Canadian winter!

It looks like there's no way to open it for inspection.

There is a threaded and knurled plug on the bottom to drain the tank , 60 miles on this and nothing in it yet!

Good that you used transparent lines. As long as there is no residue on the clean side line, you're good!

That's what I was thinking, and I resisted the urge to use a braided stainless steel hose I have in the parts pile left over from my old show truck. Another angle of the drain plug

UGH I would like to do this to Gregg but it looks like an aftermarket airbox might be required!

No you just mount it in a different place and use longer hoses.

OldBlue... Just thinking of this which you showed me a short time back and wondering if it was still working or if you would change to a catch can... you have answered the question. FIRST... the looped hose was still letting oil build up in the TB and Intake Manifold RIGHT? Let us know how this can works out after some miles. A mechanic friend told me that he had fixed this problem a few times by changing the value cover for a new one. Said that there was some kind of a separator material inside the box on the inside of the value cover where the PCV hose fitting was. In time it lets the oil be pulled through the hose and into the TB and Intake. So replace the value cover $$$ or get a catch can! Thanks for the update Steve

Steve , yeah I heard of that to, so I popped off the valve cover cleaned in a hot tank, reinstalled it , and still the oil and condensation ran down the OEM hose to the TB.
So plan B the loop hose after awhile the same results,
Plan C I cut the loop hose 2 inches from the valve cover pipe and placed a 90 degree elbow into the hose , routed the hose straight up and clamped it to the left side top cover plate of the air cleaner box, you see in the pictures. Still got some oil sucking into the TB and condensation.
The P0420 code has popped up a few times, each time I cleaned the throttle body and ran a bottle of catalytic converter cleaner through and cleared the code.
So far in 250 milessince I've installed this oil separator tank, no code, no oil, and no condensation in the TB.
Yes, it's early and yes I will keep the information flowing!!
