Anyone used one of those? I cannot keep pressure in the system, new cap and tic-tac and it still will foam over when I shut the car off after a drive. System is fully burped, it's not getting hot, running a needle width over mid point but it will vomit coolant out from the threads of the cap. Thinking a metal tank with a proper american style metal radiator cap and not plastic might be the ticket? Note, I am running the E38 setup, so I don't have the built in over the intake style expansion tank.
