I feel this guys pain. In January my 2014 6.7 Powerstroke let go through broken push rods at 163k miles. I had only owned it for 8 months and 10k miles. I really thought I did everything correctly when looking at used trucks, but didn’t know to check the engine idle hours and add that mileage onto the ticker as well. Needless to say my engine had over 230K miles with idling. But, it was cheaper to long block the truck with a DCR pump and KC turbo retrofit kit than go truck shopping again. Being you said he was a contractor, look at the idle hours and multiply by 30 (industry standard), then add to the miles. I’d be interested to see what the true mileage is and may explain why it went sideways.

My LMM just did this about a month ago, towing my travel trailer. Smoked piston cylinder #4. Ended up having a new long block installed. Let me tell you, fellas, it was not cheap. Truck only has 215k on it. Only thing I can think is, I installed reman injectors at 200k, and I may have lost an injector tip. I didn't want to pay the mechanic anymore to diagnose it and just went for a new long block, new turbo, and new injector pump. Basically, I bought the truck again. Lol. She's a 3500 dually, and I wouldn't have been able to replace the truck for a reasonable price. Sucks, but I'll get over it.

I’m curious what he was doing leading up to this happening . To be letting that much oil by Into the exhaust and that amount of blow by I have a sneaking suspicion he burned a hole in the top of his piston. Saw that happened to a guy once pulling a heavy trailer on a long grade running way too hot of a tune and high EGT’s. Definitely a thumbs up for a new short block with studs then CP4 to CP3 conversion! Can’t wait to see what he finds!

How much for a truck ? Daaaang I am guessing it is because of all the rust ... because they are more than that here in the south. BUT, you're right it's rebuild time. I would suggest that he rebuild the transmission also. Be horrible to drop a fresh engine in. Then the transmission fails.... rebuild the transfer case, drain differentials and fresh oil, and check the brakes, shocks, and suspension. It's much cheaper than buying a new or used truck. Get everything done at once and correctly. Be like having a new truck. Rebuild the engine, heads, injectors, pistons rings, and bearings.... full rebuild. Identify the issue but do everything. Pay me now or pay me later...

This is the big problem with all todays heavy duty pick ups, any repairs are way too costly! Too much "EPA crap" add on's and the whole "removing the cab" to work on them is planed misery from the builders. No need for the computer diagnosis, the blow by at the oil filler tells you it's a bad piston, no guessing! Over heated it on a long hard pull and melted a hole in the piston. This is why , back in the early days of turbo charging diesel's we had to have exhaust temp pyrometers on to know when to back off! Also the idea of adding a bit of oil to the fuel is a big help. Some guys use a 2 cycle oil to good effect, just beware of anything with dye in it as that could get you into issues with the Fuel tax guys.

This entire situation is from neglect,look at the crap that went thru that turbo wheel. Air filter maintenance was neglected or he put an aftermarket engine destroying cold air intake. Add to that you never mentioned the DPF being plugged solid and it’s got an aftermarket tailpipe,so there’s that elephant in the room as well. Because it likely wouldn’t even run if a DPF was present. It would need a new one as well. A real diesel shop won’t even work on this truck, too much going on , software issues that probably contributed to the demise of the engine , and too many parts missing. This truck needs 30k worth of work easily possibly more,unless you can buy a wrecked truck w a good driveline for parts , I’d consider parting it out or selling it as is still running but hurt .Trucks just not worth much w 170k and only an extended cab.

New diesels in stock form are junk, between the DPF system, and EGR nonsense. Also they run such high fuel pressure if you have an injector go bad the fuel can actually cut a hole in the top of the piston. I love diesel trucks but between the cost and issues I'd go with a gasser. I drive a Freightliner for my job and I'd go broke if i owned it outright. Penske owns it so they can deal with any problems, and theres been no shortage. LOL.
