I have a question for you guys.

I got the Greddy swirl pot and I'm running the Greddy cap it came with (1.3kpg). When I fill up my radiator with what I believe to be the right level of coolant and turn the car on, coolant starts pouring out of the bottom hose of the Greddy swirl pot. So, I tightened the hose clamp down a little more and put grey RTV on it and it still leaks when the cars running...When its off the leaking slowly stops.

I'm thinking I might need a new cap that opens under less pressure so the coolant can go to my catch can instead of being rejected and forced out the bottom hose of the greddy can (swirl pot). My catch can for the swirl pot has barely ANY coolant in it so instead of coolant overflowing from the swirl pot into the catch can next to it, its deciding to force its self out of the bottom port on my greddy swirl pot unit.

Swirl cap opens at 1.3
Radiator cap opens at .9 (pretty sure, have to double check)

Then I thought I could switch the two caps but thought the same thing might happen to the radiator and possibly start blowing coolant out of other weird places.

Can I switch the (.9kpg) radiator cap with the (1.3kpg) swirl pot cap? or should I get a cap for the swirl pot that doesnt open under any pressure. basically a radiator cap that doesnt require any pressure to pop open.
