Surprise under engine cover

[doc_777]

So yesterday afternoon I lifted the engine cover on the Alltrack as I was looking at the connections used for the crankcase breather. Thinking about catch cans and all that...

Anyway, one of the reasons i was thinking of a catch can was to stop the Intercooler becoming an oil trap.

so wasn’t I surprised to discover that the 140TDI has a water to air Intercooler, which is an integral part of the intake manifold! The angle it’s mounted at makes it impossible for any oil to build up in the Intercooler. The issue of oil mist mixing with egr gasses remains however, so a catch can is still on the list as a possibility.

i wonder what other little surprises these things will present me with in future.
