Catch Can Not Trapping Oil?

[vxsr33]

I was doing a minor service on my car and decided to check how much oil is in the catchcan but it was completely empty. The stainless steel kitchen scourers i put in smelt a bit like oil vapour but were not wet with oil.

just wondering why there is no oil? have i set up the catch can properly or am i just a stooge?

Thanks guys

Did you have a problem before you fitted the catch can? What do you use the car for? Oil is normally spewed out only with sustained runs at WOT i.e on the track or sometimes on the dyno.

Empty catch can is a good thing!

Can't really see your set up. Do you have a line from each cam cover going to the top of the can? Is there a vent? Or a drain?

That's how it should look no oil is a good thing. My catch can is like yours which is a sign of a healthy engine. When my engine was stuffed before it was rebuilt it was filling the catch can every 200kms which turned out to be a couple of cracked pistons.

Thanks a lot guys, thats a good thing to hear if its a sign of a healthy engine.

I just put the catch can in for preventative measure. The car is my daily and isnt tracked. I do go WOT every now and then but overall it isnt driven hard.

The line to the catch can is from the right rocker cover to catch can (non vented) then to the intake.

Sounds fine. All good.

You have a nice healthy motor.

Same goes to mine. I was worried that I installed it wrongly when after months if driving hard and I find very little to no oil.

Mine is vented out. But I only did the high load side.

The point of truth is to pull off the inlet pipe and see if there's evidence of oil vapour travelling through the can and into the inlet.

That's what I would look at. With your vent being right next to your vacuum source it may just be coming into the canand shooting straight across to the intake hose and back into the inlet manifold. You really want to be drawing through the scourers not across the top of them imo

Good point. I will do this later when i get home. Cheers mate

Pulled the hose off the inlet pipe and there appears to be no oil residue which is good news.
