    Has anyone here got pictures of their catch can install on their LS3? Specifically one with an OTR as it gives you less room to mount one.
    Im trying to install one on the drivers side, but having issues figuring out where to mount....

    I have looked on the web, but cant find much.

    Thanks

    Very interested in this one.

    Which catch can did you buy? I had the HPD one on my Silverado and while it is expensive, it has a convenient dipstick to check oil level and have been looking at this one for the LS3 I am picking up on Monday.

    I was going to make a bracket off the cylinder head, but not sure if the pulley and engine cover are going to be in the way until I see the car. OTR might be an issue for future fitment for me as it is in my plans too.

    I mounted my Elite catch can to the passengers side head with some 15mm alloy spacers and ran the hoses across the top of the throttle body to the drivers side.
    Will upload some pics shortly.

    great
    curious to know how you ran the hose from the manifold inlet tube to the catch can.
    Did you get some 90 degree joiners, as I cant imagine you could bend the hoses too much to go over the TB without it kinking?

    You actually need a slightly bigger loop on the drivers side as I just noticed that the catch can Inlet hose is slightly too short and has developed a kink. If you unclip all the other bits and pieces to the left of the TB, you can run the 3/8 lines in behind and under, then clip everything back into place.

    I saw a pic the other day of an Elite can on a custom bracket, bolted somewhere near to the fuse box.
    Right where the MSE sits...(didn't have a MSE fitted)

    I put mine on the passengers side originally because it was set up for the L77. Now I have the DOD deleted and different valve covers it's the same as an LS3, with the dirty side routed round the back of the engine.

    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. Catch_Can_1.jpg Catch_Can_2.jpg

    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.

    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!

    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?
