Cummins 12 valve timing case
Hello all, first time poster from Finland here.
So I got my first Ram 2500 4x4 with a Cummins about one and a half years ago. Just to give you a picture: 330k miles, sloppy steeringbox, steering shaft, bald tires, horrible oil leaks, dirty interior etc all the good stuff. Luckily it was kind of cheap and and I like wrenching my stuff.
All the wear and tear I can fix or live with but.. Its a KDP survivor and PO had the original timing case replaced with an aftermarket one and now it has a whine from timing gears. It comes from injection pump gear or vacuum pump gear or both. I know this because when timing cover was off I noticed that those gears dont have any play in them relative to cam gear. And I removed the upper dowelpin and gave a little smack to the side of the timing case and the whining got quieter.
So my question to you is: Is this a thing with aftermarket timingcases? Original timingcases are pretty hard to find here and I dont want to change it to another aftermarket part just to notice the whine again..
