get a used motor from a salvage yard. Lots available from low mileage wrecked trucks. Definitely an option.

I bought a reman 5.7 Hemi from Powertrain Products in Baltimore, a little over $4k with the install kit. They provide a 4-year/1M mile gtee, better than any other source I found, and they’ve improved on some of the OEM engine failings, valve seats, oiling, etc. I have 6k miles on it since May and very happy with it, except the ave mpg is down about 4mpg. It does take awhile to wear in, but once I had about 4k miles on it the juice is as good as ever.Just buy one of MMX , Remans are garbage
When you have an engine failure that includes busted metal parts, especially in the head/valvetrain, you will get metal fragments in the intake. If you put this intake on a new engine, these metal particles will be introduced. New intake, $300 = peace of mindPardon my ignorance, but what does the intake manifold have to do with a failed lifter/cam? There's no oil passing through it, only air/fuel mixture, correct?
Or is it a physical thing where it can only used once and won't mate up correctly a second time since these things are not metal anymore?
Ok, if you say so, but I still don't get it.When you have an engine failure that includes busted metal parts, especially in the head/valvetrain, you will get metal fragments in the intake.

Yeah, these failures are definitely putting a hit on their reputation.
I had lifter fail on my '09 Ram 1500 at 140,000; gouged the cam, etc. Buddy is a mechanic, so was able to fix for around $2k. It is definitely a known problem, and for Fiat NOT to allow some $ for customers to offset repair costs, don't know I'll be sticking with Ram..... BTW, after fixing this known problem, 20k miles later valve seat let go(another known problem with the 5.7 hemi) and caused piston to shatter. New engine time.
Say the intake valve fails and is open to manifold; any metal fragments in cylinder is now going to be pushed upwards into intake manifold ( see my pictures in this thread; my intake was loaded with metal fragments)Ok, if you say so, but I still don't get it.
Unless things are different these days, there's no oil running through the intake manifold. So, how would oil contaminated with shards of metal get into the intake manifold?
The only thing running through there is the fuel/air mixture, right?
Maybe I'm ignorant or just old and outdatead?
Most reputable shops switching the engine would clean the intake...Say the intake valve fails and is open to manifold; any metal fragments in cylinder is now going to be pushed upwards into intake manifold ( see my pictures in this thread; my intake was loaded with metal fragments)
True. But the remanufactured hemi i installed noted that the warranty would be void unless a new intake was installed.Most reputable shops switching the engine would clean the intake...
Man, those pictures are scary! That's some serious failure!Say the intake valve fails and is open to manifold; any metal fragments in cylinder is now going to be pushed upwards into intake manifold ( see my pictures in this thread; my intake was loaded with metal fragments)
My valve seat failed, got chewed up between piston and head/valves, eventually breaking intake valve off, leaving open hole to intake; piston pushing all this mess up into intake before piston finally exploded. Oil was not in intakeMan, those pictures are scary! That's some serious failure!
I believe you, but my thick head still doesn't get it.
If an intake valve stays open, it's only open to the top area of the cylinder above the piston. There is no oil there (compression chamber). Unless your rings are totally shot, how can oil get into the compression chamber? it's just compressed fuel/air mixture. No?
Ah, different story! I mistook what you were saying. I thought you were saying oil contaminated with metal particles got into your intake manifold when actually chunks of piston and valves etc. were forced in there. Dang! That's catastrophic!My valve seat failed, got chewed up between piston and head/valves, eventually breaking intake valve off, leaving open hole to intake; piston pushing all this mess up into intake before piston finally exploded.

Correct! Yea it was catastrophic, especially since I was 600 miles from home. I would hope Ram has corrected these inherant problems before I would even consider Ram again (especially at the prices they want for them now)Ah, different story! I mistook what you were saying.

Damn! I feel for you. That thing was a seriously blown up bag of junk.Correct! Yea it was catastrophic, especially since I was 600 miles from home. I would hope Ram has corrected these inherant problems before I would even consider Ram again (especially at the prices they want for them now)
The way that lifter cut through that cam lobe like butter is pretty ridiculous. It's pretty clear that the cam was of a garbage quality. All the lobes look to be worn significantly, just crazy, must have been some real soft metal.
