'98 ZX2 engine chirping noise, belt? NO!

My daughter's (new to us) 98 ZX2 came with a chirping noise. I assumed belt tensioner or the infamous timing belt. After much searching on various forums, I found it was not belt related at all.

It is the round crankcase breather filter, part number FA-1661. Gets clogged and the back pressure makes it wheeze with a high pitched squeal.

To verify, just start the car, wait a minute for the squeal, then remove the oil filler cap. If the noise goes away, that's your problem.

Only Ford or on-line supppliers carry the filter. Takes 15 seconds to replace. My dealer had it for $19. Rock Auto had it for $11.

Hope this helps someone else!

Thanks for info . Most people like yourself would think of belt noise but this would be a far simpler cure and easy check .Might help other members with similar complaints .

Yep. As the PCV sucks in and there is no way to vent elsewhere it will pull the crankcase into a vacuum.
