Volvo air filter

[RIBW]

It is a long time since the filter was cleaned, to be honest if it ever has been. There was a previous thread where the washing the air filter seemed perhaps ineffectual. For a minimal cost, had reckoned that buying a non branded off the shelf filter seemed a better approach.

Just a bit of pedantry: The item under discussion for the 2003 is referred to as an 'Intake Silencer' by Volvo (i.e. not a filter). Having said that, it probably trapped a fair number of flakes shed from the anechoic material in the engine compartment!

Photos of a cut apart item attached. Mine took a week or two of immersion in diesel with an occasional shake to flush out all the contaminants. The mesh half now serves as a silencer on my test bed engine in the garage.

Good luck

This raises a query for me!! I was always told - give a diesel engine clean fuel, clean oil and clean air and it will run forever.........
If this volvo part is only a sound deadening device, not a filter, and from other posts here, some engines dont have any air filter at all, is this not leaving the engine exposed to taking in debris, however minimal and fine, direct into the engine....???

I know a boat is a "relatively" clean environment etc, but still, surely you would want some kind of protective filter on the air intake?

What am I missing??

You're missing the instruction in the Operating Manual, which tells you to remove the intake silencer every season and "wash in diesel oil and rinse thoroughly". The silencer contains a coarse mesh filter.

The silencer contains a coarse mesh filter.

Which stays tacky due to the crankcase breather. From memory I think it would just about stop a grain of rice.
