Air Cleaner Dump Valve - LR90

The dump valve will be on the 'dirty' side of the filter - no damage done.

Dougal,

Thanks for the clarification. Good to know I've not caused damage to be done!

I thought there were two of them, one drainpipe style one on the dirty side, and another whoopee cushion style one on the clean side on the filter itself? ISTR having a branch sticking out of the one on the air filter!

Ian - your descriptions are lost on me!

The normal one is the rubber nipple on the underside of the main filter housing (and/or possibly on any plumbing leading to it) to allow any water that may have entered to leave under the influence of gravity.

I can't see a point in having any valve between the filter and the engine. I've never seen one. The only thing sometimes installed in this pipe is a filter restriction indicator (perhaps that's your whoppee cushion!). There should be a sintered safety filter between the indicator and the pipe to avoid dirty air bypassing the main filter should the indicator get knocked off.

There are two water trap valves on my Defender, but now I think about it they are both on the dirty side. One is on the pipe between the air intake on the wing and the other is the one you've spotted on the filter itself.

I'll have a look at mine this morning and report back later.

Replying to own post.....

Removed the air filter cover to expose the base. This revealed, as Dougal said earlier, a single square hole leading to a short circular drain pipe. Nothing is attached to the drain pipe - the missing dump valve should be here...

On a positive note this is on the 'dirty side' of the filter.

I'll order a dump valve and fit later.

Thanks for your replies.

Regards

Richard
