Emptied my catch can today and was expecting an oily kind of liquid but
found it half full of murky, rusty water with a tint of petrol smell :shocked:
Tell me this is normal please :smiley:
Thanks.
-
done over 1700miles and only now have to change my catch, sign of a healthy engine :cool:
-
it's not rusty water, just oily
-
that is perfectly normal.had catch can set up on my last trackday scooby and all that ever came out was petrol smelling water...sign of a decent running engine.turbo cars run better with a catch can anyway as the oil mist that it catches would normally go back into intake and that reduces the octaine rating of the fuel.saw an extra 11bhp on my scooby after fitting one.

oil vapour lowers the octane of fuel

probably not on a Golf but you never know with Jap

10mm and 15mm? :undecided:
-

mine ran only on 99ron fuel and the car ran so much smoother after the can was fitted.you should check the inside of your intercooler and see how much oil vapour is going into your intake.well worth while mod and even fitting my spare one into my mk4 1.8t even though its standard.

No need to sell it to me mate, I was one of the first on here to fit one :afro:
-
10mm and 15mm? :undecided:
not the nut the thread
-
its an odd thread (not BSP) if i remember correctly think it might be an american thread or summit, ill check tomorrow gimmi a poke so i remember!!
-
cool thanks need to get the 19mm ones made :smiley:
-
tbh there is no point as the thread is still gonna be about 15mm so its gonna reduce into the can anyway, you may aswell do what i done and put a piece of rubber hose onto the 15mm nipple and the 19mm hose pushes over that. works perfectly :wink:
-
i did think about that wasn't sure it would work will just do that then cheers will be fitting it tomorrow then :smiley:
-
or you can purchase actual reduces from the bay a dozen a dime, i'm using them, cant tell theyre there and its water tight :cool:
