Engine air filter came out blue and damp

Changed the engine air filter today after washing the truck. The filter came out damp with some blue staining, particularly around the edges of the filter. Only thing I can think of is that I forced some water into the airbox, along with some pooled windshield washer fluid, when I was pressure washing the hood. The airbox did not appear to be damp from the outside. I did not notice any cracks or chips in the box.

I am very careful about sealing the box properly when changing the filter, so I don't know how any liquid got in. I live in a hot, arid environment, so I don't think the filter had been damp for a while; there was also no sign of mold. But I haven't changed or checked the filter since the fall, before rainy season.

Any other ideas how this could have happened, or what I need to do to prevent it from happening again?

Thanks

 

That air box seals to the filter if u use a pressure washer ..water can get in .u can actually see the filter slightly when the box is sealed .its just 2 clips and plastic pieces holding it .

 

Fine, you and your pics. TRD Blue Performance Air Filter (MSRP $239):

 

“ TRD blue air filter”? I live under a rock, please link this product..

wait OP you making a joke? lol if so nice.. I’m slow.

 

Oh boy...

 

The OE filter has rubberized edges, maybe that’s what it’s for?

 

You gotta be shitting me……..

 

Perhaps it’s expecting. I predict a ‘lil new cabin filter around shortly.

 

That's a filter for the 4-cylinder engine. Don't think they come with the rubber seal like the 6-cylinder filters.



The blue staining does make it look like it was exposed to washer fluid. Did you fill the washer reservoir before washing the truck? I wouldn't think a pool of washer fluid exposed in the engine compartment would last very long under driving conditions.

 

It’s not pink!

 

It’s not

 

I'm curious who sold him yzz04 filter for $239

 

This is not what I was expecting to see... (and it seems I am not the only one surprised!). The pic looks nothing like the Taco filter used in the V6.

Do you have a 4 cyl by chance? I have no idea what that engine's filter looks like.

Again, I do not know the 4 cyl. - but unless the washer fluid reservoir is the filter box; I cannot imagine a situation where your air filter would get unintentionally soaked in washer fluid...

 

ah okay, I didn't know the 4 cylinder was different.

 

It is a 4 cylinder. Yes, I remain mystified how this happened. I will need a keep a closer eye on it after washes, I suppose.

 

Don’t use a pressure washer, that will prevent most of this from ever happening again. There’s absolutely no reason to have a pressure washer underneath the hood. Do you feel the need to wash it? Use chemicals and use a garden hose

 

ill be back im going to check my engine filter ..

 

Congrats it’s a boy!
