I'm looking for a lower timing belt cover. Mine got chewed up in the wreck the PO was involved in. This one:



Thanks!

 

You want part #B660-10-501E. If the engine you get a used one from has ever leaked, it's highly likely the cover is swollen and warped (like the one you pictured). They then tend to fit poorly and rub on belts and pulleys. Grab B660-10-521B as well, that's the middle one. The upper one rarely has issues. Together, those two are $51 + shipping according to my mazda comp account, not too terrible if they save you from having to tear down the front of your motor.
