put mine in passenger side infill panel and sealed with pinch weld strip.

SS Flo Ruder, if your foul air return is going back post throttle body, what did you do with the inlet at the valley cover?

I mounted mine off the front of the motor on 2 x M8 tapped holes that Holden put there for me. :)

I don't have OTR yet, but I believe this will clear.

Out of curiosity, how much oil is typically being caught in the catch can on a LS3?

it depends on how much you flog them.
first few 1000 kms in mine I gave it a hiding and collected maybe half a tea spoon.
have since done another 500kms diving normally, and nothing.

that is a good set up.
well played.

Thanks Murdoch,

I only spent a week with the catch can in my hand trying to find the best place to fit it before I found the 2 x M8 holes in the front of the engine. Haha

Measured the position of the holes, modelled the plate on CAD, cut it out, bent it and it all bolted straight up. I used Speedflow 10mm Silcone vacuum hose and it literally took 10 minutes to install.

I have only done 50km with it on, but when you pull the dipstick you can smell the oil vapors in there!

What I meant to say was PRE throttle body, SS Flo Rider

I’ve got holley valve covers. I connected both banks through a tee piece

I ordered Red Holley Valve covers on the weekend Flo Rida, would you be able to post some pics? Or email them to me? I'd like to see what you did with the coil mounts and wiring if possible?
