It’s got to be the mds and maybe a oiling design problem with all the idling the cop cars do. He’ll there were days when some guys would only put 30 miles on the car a shift!

i hear that the mds plug switch when off not opening up all the way and u can see on lifter its all dry when pulled !

I just had this come up on my Ram at 100k miles. I spoke with the Jasper rep who tells me that the factory 5.7 hemi is such a close tolerance engine that it was designed to use very thin oil. So the oil journals are machined very narrow because it was easier and faster to machine. Over time the delay in pumping the oil up to the top end of the motor through such a narrow passage causes premature wear on the lifters and cam. Jasper apparently addresses this during their rebuild process and opens up the journals. I have one arriving tomorrow ( way faster than OEM cam and lifters). I hope I don't regret it, but Jasper's warranty policy is pretty damn reputable.

What about buying a used engine? We bought a used engine and had it put in my brothers toyota about a year ago. Running great. Cost about $2700 for the engine and the install I'm sure a 5.7 would be more but it might be a way to go for you.

Here's where we bought the engine.

I was playing around awhile back looking at reman Hemi's. One of the company's I was looking at actually said their remans had updates to fix this problem or that. Can't remember what company it was and several of them won't tell you crap unless you put all you're info in like you really want to buy one.

I was actually just watching one of those Saturday morning gearhead shows and they had a part of the show just about the hemi cam and lifter problems. They actually based it off the mds lifters being weak especially at the head where they are thinner for mds. They highlighted Arrington Performance for coming up with forged lifters of course non mds to solve this.
