It isn't working proper. Have you connected it up the right way?

Do you have a lot of crankcase pressure? If so, it is likely your head gasket is blowing. That will force a lot of oil vapour down the breather tubes.
It is a fairly easy fix, use a quality Payen or Elring gasket, and fit the catch can properly as a failsafe.

No " chuffing " when you rev it up with rocker cap off?

Post a pic of the can, and your breather pipe setup.

OK, so if you remove the black braided hose, and plug the long red pipe into the rocker cap, and the short red hose onto the spigot on the air filter intake, you should be in business.

I dont really understand why that should be, the catch can should reduce any oil going into the air intake, not increase it. So long as your air filter isn't getting oil on it, that is fine.
And that is an impressive record for a Ninety, mine is good too, although at the opposite end of the mileage spectrum. Only 30k on everything under the bonnet.
And it has been completely trouble free, once the initial sortout on purchase was over, no issues since 2009.

I can!
The intake is sucking the oil fumes out. I reckon that there is little or no resistance to the air flow through the snatch tank. Instead of connecting to the air intake, try allowing the output from the catch tank to open to free air. See if that makes a difference.

I agree, but the intake shouldn't suck any more through the can than through the standard braided hose.
I use a simple solution, I just run a long pipe down through the engine bay, and into a fitting on the chassis, fitted in one of the holes inside the chassis rail aft of the bottom crossmember!

Is there a filter in the normal hose? I think there needs to be some form of baffle/restriction in the catch tank. It might be worth stuffing it with loose wire wool to act as a trap.
