Camshaft synchronizer drive gear replacement part

That would also be known as the camshaft distributor drive gear and it drives the cam synchronizer as well as the oil pump. I use parts directly from the dealer for those as you need to replace both the one on the cam and the one on the base of the drive and I have seen more than a few aftermarket sensor drive gears that don't match up properly with the Ford drive gear which leads to rapid failure again. I know you can get aftermarket gears for the bottom of the sensor drive but I don't know of any of the drive gears on the cam.

I would also recommend replacing the oil pump if you haven't already, it can wear and greatly increase the pressure needed to turn that gear and damage the teeth that way. Be sure to pack some petroleum jelly in the pump gear teeth if you install a new pump, they don't prime well if dry and that method helps a lot.

From that area it should have hit he pan. Then through the pump and into the filter, as long as the filter wasn't plugged enough that it didn't open the bypass most of it should be trapped in there, maybe cut the filter open and see what you find. Once you have it together it might not be a bad idea to run some cheap oil through it a couple times to flush the rest out.
Parts wise it's been a roll of dice here, some stuff is on the shelf, others seem to be shipping on the back of a sloth.

Great to hear it's up and running. Thank you for using 2CarPros.
