How to connect catch can to LT2 manifold

beowulf556 · 08-22-2025, 05:50 PM

So I just put on my lt2 manifold and decided to get a catch can after seeing oil build up in the heads. I'm debating on how to connect the catch can now. I bought a 90 degree fitting which worked great with the hose I made for the lt2. The catch can comes with the quick connect fittings. I'm wondering if anyone has found a 90 degree adapter for the lt2 intake that will work with quick connect fittings? If not, I guess my only option is to cut the fitting off the catch can hose and just clamp it on? Trying to make it as clean as possible!

Put the hose in the sun for a bit. You'll probably be able to pull the fitting off when it's hot as the hose will be more pliable. Then push the hose on the barb on the 90* fitting.

Here is what I ended up doing, simple hose clamp.

I have the Mishimoto catch can with the quick fittings and bought these from Amazon. They fit perfectly.
