hunting DPF

A good quality catch can on a modern diesel is a no brainer - manufacturers should be fitting them as standard (or at the very least an optional extra).

They do mate, the tappet cover has a very complex oil separation system, but it's hindered by both space and heat, the remote catch can being a bit cooler is a big factor.

Wasnt aware of that - good info, thanks.

After seeing how much crud was in my intake manifold after only 35,000km im very glad I cleaned it out and fitted my catch can. When I removed the intake parts again recently (at approx 70,000km) there was nowhere near as much crud in the intake (probably only 20% of what was there before) and it was much easier to clean this time.
