Oil Catch Tank Advice

Hello,

I'm looking to install an Oil Catch Tank and was wondering where it would sit in the EVAP system?

Currently the system has the following pipes:

Rocker Cover to Just Before Throttle Body
Rocker Cover to the Inlet Manifold
Charcoal Canister to PCV Valve to Inlet Manifold Can I put all three pipes into the catch tank so nothing goes back into the engine or should I make an inline catch tank and if so, where should it sit?

I can provide diagrams is required....

Cheers
Stephen

PS: New here :) I've had a good look around the forum on the topic and couldn't find what I wanted to know. Hope someone can help a newbie :lol:

I have a catch can on my Sentra, but its only in the PCV line, not the EVAP. I just put it in the line from the PCV valve to the intake manifold.

I don't have a line from my fuel tank to the PCV valve. Why would you want a catch can on the EVAP system?

PCV (in valve cover) - - - > Can - - - > Intake manifold

I'll see if I can get a picture of it tomorrow morning.

I've done some more reading and what I've labeled as the PCV Valve is actually the Canister Purge Valve.

Relooking at the engine, the PCV Valve is built into the top of the Rocker Cover.

Are you saying I should have the EVAP system going into the OCT or does it not matter?

You help is very much appreciated :)

I left the EVAP system alone. All it should do is capture evaporated fuel from the tank and send it to the engine to be burned. By stopping this, you are only wasting fuel.

The can is there to catch any oil residue that is being sent through the PCV line.

Catch cans can be very dangerous if in-correctly installed, or not emptied, or the wrong shape and size.

I have seen engine fires started for all of the above reasons.

Cheers for your help. I'll post up some photos of the completed tank when I get round to fitting it :)

Thanks for the warning... I'll be sure not to blow anything up!!!
