Ram 6.7 issues

[badhattitude]

So I know so many people online trash the 6.7 as unreliable. I finally have a decent report on the long term reliability of this truck.

It seems all the trouble is because of the emissions crap. Clean the EGR system and it's not bad.

The engine ran like crap so I just tore it down in my driveway.

The EGR cooler and bypass valve were tested. The cooler had a small leak. Some sooty contamination in the coolant. New cooler ordered.


My exhaust manifold had 3 broken bolts on the 2 back cylinders. It caused a leak and the soot that made it run so bad. The manifold had warped and was out by a sixteenth of an inch. Re machined and cleaned out.

The EGR bypass and valves need cleaning but no more.

So after many oil and filter changes, 2 water pumps, 1 turbo and a radiator I'm figuring the 330,000 miles were pretty reliable

Time to put her back together.

So wait... following the manufacturer's maintenance schedule keeps these things alive?

Keep it under your hat. You'll kill the business.

I wonder if penisis and pisspal can improve on what the manufacturers maintenance schedule?

I hear all the chopped trucks have issues especially transmission problems. I left it stock.

Why no delete?

The tuning is a pita be and tuners are hard to find.it's easier to just keep it stock. The maintenance isn't bad considering how many miles I get between needing work. I don't have 5 hours of time in maintenance of the system since 2014.

Update.

I had some manifold gasket debris get into the turbo. It's not a simple turbo and a rebuild locally is not possible. Although Derek could get me one cheaper ($500 less) I'm having a local shop don't help work so I can get to other things.

I'd have loved to just clean and reassemble the thing but I think it screwed up a few things inside. There's an oil leak and it locks up intermittently. It's a bitch to get to so I think I made the right decision.
