Hey everyone i was given a Cusco catch can for my 9 and i figured i might as well install it. The only problem is it came off another car so it has some old oil left in it. I wanted to clean it out before installing on my car but the catch can itself is sealed and doesn't open in any way. i was going to take all the fittings out and maybe soak the entire thing in de-greaser or something like that. Any other ideas? Thanks

 

Brake clean and a rag

 

brake clean, or you can put it in a solvent tank and run some through it.

 

Yeah i gotta figure out a way to clean the inside of it being that it doesnt open

 

Drill a hole in the bottom of it, tap it with a designated size, then use a bolt to seal it back up. Then you can clean it out/drain it anytime in the future by just removing the drainage bolt.
