Just serviced my gf's Ford Fiesta.
I took the air-filter box off to replace the air-filter and I could hear something rattling inside which I assumed was a broken screw, but after failing to see any damaged screws I was confused.
Anyway, opened it up and found these weird things which were like cubes and hard, but could be chipped away at with a screwdriver?
I am totally confused to what they are and how they could get into the air-filter box?
There is NO way they could have been flicked up from the road as they are too heavy and there is a winding system of pipe-work for them to have got through to get to under the filter element.
The ONLY thing I can possibly think of is some kind of 'moisture attracting' cube put in there by Ford? The car is not very old ('58 plate).
Any ideas?
?
