Im thinking of fitting an oil catch tank, are these a worthwile pratical investment, or are they all show and no go I.E. just something else to polish

 

Not if you spray it matt black and mount it out of sight like I did LOL

Worth it if you're worried about oil contamination in your intake. Even if they're not overfilled with oil, they tend to blow a lot out of the crankcase breather - better to catch it and drain it every now and again rather than just let it go through with the intake charge.

 

many thanks for that i will invest

 

just checking. can i diy it by just diverting all the breathers into one chamber. i presume it would also need a vent and have good access to enable emptying?

 

i've got a perrin catch can from tracktive
