Thread: Wading too deep...

I don't know about the Pumas but my 300 TDi had a dust release valve on the air cleaner and a water trap in the air trunking (at the lowest point) before the air cleaner body, I couldn't see the point in raising the air intake without blocking these.

These are (or should be) designed to seal when the engine is running - however over time they do perish.

Gerry (1103.9D ?) on here modified his air cleaner so that a baby bottle fite in place of the dust release valve. Seals but still allows visual inspection.
