odd one this really, as before, in other racing ive done, the catch can only had to be easy to check,
as in it had to have an easily accesable balcock type valve that could be flicked open to prove the can had no fluid contents within.....
this is the device i now have fitted to the lex as a coolant catch can.
an easy alternative to the catch can is to fed the breathers back into the intake. its how i did it on mine, just fed the cam cover breathers back into one of the turbo air inlets.....however i dont have any oil being blown about so i suppose its an easy option for me
