Catch Can Routing....

[dhutton]

To the best of my understanding (which is very very little), there is no air port on my intake system. Ive looked all over and found nothing between my MAF and throttle body. Perhaps this is because this LS3 is a crate engine and not the ones in a modern car?

For the top fitting I could find absolutely no info from Mighty Mouse and almost nothing online about where it is supposed to go to. The only thing I could find was a video of a guy installing this same catch can on a C6 Z06 and he said the top fitting was to be attached to tubing leading to anywhere under the car and that then said something about how if the "oil boils" or something like that then the catch can would release the oil from the top to get it out of the engine.
... personally, I have no freaking clue.
Any thoughts?

You have to drill a hole in your intake tube and add the fitting to connect the hose. The GMPP crate instructions are very clear on this point.

I'll look back through the instructions that (I believe) I have. I had a shop install the engine and do the swap, but Im pretty sure they gave me the GMPP instructional packet. Do you happen to know, once I drill into, and attach a hose, the intake tubing, where that new tube is supposed to run and attach to?

It attaches to the fitting on the passenger side valve cover where it appears you have installed a filter.

Thakns for the detailed info Clint and Don. Ill get on that and get it installed this weekend.

I've taken the car for a quick 20 mile jaunt with the new catch can and that thing Hisses like a mother****er!
I looked around online and some people seem to say this is regualr while others say our catch can should be pretty quiet.

What I did notice, and confused me is that there is a little twisty knob on the bottom of the catch can, to let the oil out. I currently have it closed all the way.
Yet, when I put a finger over it while the engine is running (and I have that annoying hissing noise) it completely cuts out the hissing noise. I thought the
bottom was supposed to be the drain, making me very confused as to how/why it is sucking in air?

My tiny brain is very confused.
