As outlined in the “When suppliers turn bad” thread, 635 (Ted) had Diesel Depot put together “The Best Ever 6.2 6.5 Motor Rebuild” based on a 6.2 block with 6.5 heads. The build was outlined in MaxxTorque magazine Vol 1, Issue 4 Best Ever 6.5 Diesel Rebuild. If the Hyper link doesn’t work: http://maxxtorque.com/dieselcommunit...diesel-rebuild

The original build called for a SCAT crank and a full set of Cleveite bearings. But what he got was a stock crank (as mentioned in the article but it was on the build sheet Ted has) and a partial set of Clevites with one King bearing placed on the compression side of #7 which, after 25K miles, flattened like a penny on a railroad track and, as you can see, carved the crank in a way not in the design or druthers of the owner. :mad2:

The full demise happened in March of 2011.

It has taken a year of phone calls, emails, memory refreshing and all out arm twisting but, most of all, patience on Ted’s part to get Diesel Depot to honor most of the warranty and get the replacement parts shipped to him.
So, Finally, Ted has received, (months are approximate):
August: Scat Crank turned down to accept the two piece rear main seal, the two-piece rear main seal, Balanced fly wheel.
October: The heads, which were ‘gone over’ (nothing done).
Late December: ceramic coated top/teflon coated piston skirt pistons, connecting rods, camshaft
January: Rings, lifters
February: overhaul gasket kit and the bearings.

Wouldn’t you know that the last thing they shipped to him was the Clevites and they are still holding out on the promised check to “cover” labor (they claim $40hr is all that is charged in GA so if you’re going to break down, do so by Diesel Depot in Sandersville GA cause their labor charges are lower than most parts of the Third World)! :skep:
 
Oh yes, memories! Trials and tribulations of dealing with Diesel Depot!

But the engine components are not mine anymore, they have been sold and will be installed in a much lighter and very nice white 1/2 ton 4x4!

Hmmm I wonder which truck that will be???????????????
 
Thanks Ted
Yes, I got the “Luck-o-the Irish” and am able to purchase the motor which will be assembled by Todd Hughes who’s day job is the right hand man at Heath Diesel. I guess I should call the motor “6.35 R (for resurrected)”.

Included is, well, everything: GM-8 Turbo, Extrude-Honed Upper and Lower intake (OEM Upper and a Peninsular Upper so I can still use my coveted spacer), etc. The block has been hot tanked and magnifluxed; will get the crank line confirmed (?Center Bore?) as good and then the assembly will start after Todd’s truck is up and running this month.

Debate is still on and $$ will dictate if I’m able to swing the higher quality Rod Bushings (NASCAR type from a shop in NC that I still can’t get the metal type identified) or the Harland Sharp Roller Rockers. The rockers can be done later, a PIA but not like pulling the motor to replace bushings.

I had originally thought to put the motor together myself but with my experience levels (next to ZERO) I’d leave something out, put it in backwards, etc and with the cam kit and tune being added to the mix, having a team of “German Scientists and Three Wise Men” was a much better option. I would have originally driven up there to swap the heads and ancillary parts over on to my block and picked up the un assembled DD motor parts anyway. Might as well pull and swap in completed long blocks instead. Doesn’t take much more time and Todd's work is unparalleled.

Ted has decided to keep the truck, 98 ext Cab 4X4 Long bed Dually, but wants to install a basic 6.2 motor with 6.5 heads attached with ARP studs (Technically still a 635), a Heath Tork-Thrust #4 Cam Kit (towing) and Max E Tork T4 Tune.

I almost got his 98 Truck, Trailer, 6.2 motor and the un-assembled DD motor for a song but knew that would be screwing over a friend, even a very frustrated one wanting to be put out of his misery. Not happening and with a workable plan in place, friends to get him through, it’s all coming back together for him.

My IP, starter, Heath Goodies (water pump & Fan), TM, PT Wiring Solutions Battery Cables and GP Harness will get transferred/installed to the “6.35 R” a t the time of the swap out. Ted will take whatever he needs/wants off my 141 block, Heads being the most needed (and, if they aren’t serviceable, I’ll do what has to be done to make that good), Turbo, Upper and Lower Intake (OEM) and so on, to put his 98 3500 back on the road.

He’s also got an 81 short bed reg cab 250CI Gasser that he’ll swap in an NA 6.2 later but that’s still another story…He just wants his original truck back together in reliable form, able to tow as needed and not have to worry.
 
I believe I will be stuck with this beast for a while longer! A Todd rebuilt 6.2 with 6.5 heads and Bill's towing cam will work just fine. Still use the WMI and Propane.

Hopefully the 6.2 engine swap to the 81 should go well.

Bruce, thanks for the conversation a while back on the rod bushings. Sorry for my ingnorance on the topic and the lack of details.
Do the ones I'm refering to from NC ring a bell now? Bill had mentioned he got the source info through mutal friends who put him in contact with Yates Racing.
From what I understand, the bushings are inserted as a solid disc then machined out to accept the wrist pin with a tollerance of one fortieth of one thousandths.
$340 for the bushings, machining is extra.

Any insights would be appreciated.

Paul

That dosent sound too bad Paul, hard to do better than Roush Yates when it comes to water heaters
 
Water Heater? Too funny or am I missing an inside joke?
But does the bushing sound familiar and just what should I be asking for?

Water Heater is what we call racing Engines, On a custom bushing thats probably the only way to do it Paul, Ill check with a friend of mine who builds High end Marine engines
 
That engine looks great, very nice work! Any ideas for an upgraded turbo? All that work to beef up the motor seems pointless running a gm hot air pump turbo.

1) That engine is a beauty!

2) You're not really gonna put a PURPLE spacer on that are you!!!?

3) The KW is a work of art.

4) When I'm visiting in the Woodland Park/Co Springs area I can lay down a cloud to make the prostock pullers jealous. Nothing like altitude for a great soot cloud.

5) I always enjoy these kinds of entertaining (folksy?) threads from our friend Paul...


Ok that was 5...

GM heat pump. Hmmm...... I had a GM8 on that engine and it did push over 23 pounds of boost pressure. Had an ATT also later and really liked it even more, it too would generate a ton of boost! But the area I lived in didn't have a speed zone above 60 for miles in either direction so I went back to the GM8. The WMI and Propane came on around 2 and then 6 pounds of boost in the low 60mph range.

Im sure you had no problem getting 23psi with it, guys get that all day long with these turbos. Thats not the point, the gm turbos produce so much back pressure, high egts and high iats also loses efficiency around 14psi.

Just figured it would be the safe route to go by upgrading the turbo on well a built motor, rather then choke it with the gm turbo. At least your running wmi.
 
I think paveltolz is empty most of the time, so a GM8 wouldnt be an issue IMO. If it is a big problem, he can sell the GM8 to me! :)
