They are definitely promoting it now, lol. The fact that the stock internals held up to over 4 times the amount of stress it was designed for, repeatedly, on used bearings and rings with a cylinder with a rust patch...well, sounds like GM has that platform pretty well developed.

I don't know if y'all read Hot Rod magazine, but they decided to do a test with a 5.3, and see how much turbo boost they could throw at it before it blew up. The engine was junkyard fresh, they reused the bearings and rings, did a couple of very minor modifications, and let her rip. The...

I've been asked this question via PM. If the fan clutch is indeed working normally (and you'll definitely hear it cycle on and off), then that's good, a bad fan clutch will certainly cause an overheat. When the thermostat was replaced, was the little tickler valve oriented at the very top...

I need a different explanation, considering I'm not a driver, nor am I familiar with the politics of trucking.

Wow, that thing looks like a deathtrap.

Kind of big deal: Many 08-10 trucks (DPR only) have had a recall issued, with improved software to enhance regeneration performance. Exhaust brake settings have been revised downwards. If your DPR is visually failing, you get a new one. So if you've been having regen problems on an 08-10...

I asked the owner of my shop if he'd heard of a 9 speed in a Hino SG. His replay was yes, they did, but it was not popular. The engines made enough torque to make the three extra gears unnecessary, and they weren't coupled with a reasonable rear end ratio. Maybe good pulling mountains, sucked...

Another question: why did they replace the dpr? What caused it to fail? Sent from my DROIDX using EO Forums mobile app

What year is the truck? Model, engine? What is your complaint? Egr valve failure? Turbo is leaking what? Exhaust gas? Oil? I'm assuming oil. It's fairly common for them to leak some oil, and that by itself is not going to be covered by warranty. Did anyone measure radial and axial endplay...

Got it. Gimme a minute to check it out. Sent from my DROIDX using EO Forums mobile app

If you want to add flexibility to the truck's ability to regen, take it to the dealer and have the "rental car" flag under engine customization changed from 0 to 1. This will allow a parked regen at any time. The DPR indicator could be at zero and you can still force a parked regen. Helpful if...

They were rated up to 300hp. The dt466, which the 530 was based on, was a reliable engine. Not particularly powerful, but solid. Millions of school buses had them. They use high pressure oil to pressurize the fuel in the injectors. Since the oil has this dual purpose, it needs to be changed on...

As far as I know, there are only a few notable differences between the DT466 and DT530. The DT530 has a longer stroke and larger injectors, and were rated up to 300hp.

I'd shoot allways a pm. I think he's got the fleet version. I've never seen it in person. We used to see them come in pretty frequently with regen problems. They issued a few recalls over burner ignitors and bcu/ecu reflashes, and just like that, warranty business dried up. Lol. In particular...

That is an excellent question. 11-13 trucks have identical Dpf/scr systems. If the maintenance schedule is followed, the driver is given adequate instruction on how to treat the truck, and only clean def is put in the tank, there's little issue. Initially there were quite a few bugs that needed...

Yeah, I noticed they don't cross. Im gonna dig around and see what I can find. Sent from my DROIDX using EO Forums mobile app

Were they the same as the $22 ones I mentioned earlier? We should start a parts cross reference. Sent from my DROIDX using EO Forums mobile app

All of the conventional trucks from 2005 up are built with common American chassis/brake/axle/driveline/transmission/suspension/steering parts, all of which should be available from regular parts suppliers. If one can cross reference these parts, they can be obtained nearly anywhere. Sent from...

It would have had to go thermonuclear to crack the block. Only time I've seen the block crack is when a rod goes through the side of it. Granted, anything is possible. Id inspect the block deck for cracks. They make a penetrating dye kit to do this. Sent from my DROIDX using EO Forums mobile app

I think that's a pretty fair analysis!
