GSC 6.5L turbo diesel. Things to look at when purchasing a 6.5

6.5L diesels.
Check the coolant. Oil. Fuel pressure. And the typical GMT400 issues as you work your way through purchasing a 6.5L diesel as a work truck!

Make sure the front brace is on the starter. Without that the block will crack out were the bolt goes into the block.

My 94 GMC 2400 had 400,000 miles on it when I bought it. It was run daily and I put 110,000 MORE MILES ON IT. In its life, the 6.5 Diesel had a new Head Gasket installed at 250k mark, a rebuilt injector pump at 465k, new injectors too. Im sorry I traded it in. I had an offer to sell it on the spot … from a total stranger. These 6.5 diesels are truly great motors.

For those who buy the 6.5TD and the PMD is in the original location, if you get a non-start, don't listen to the GM dealer, because he'll want to sell you a whole new injector pump assembly, which the PMD is part of. GM doesn't sell the PMD alone (or at least they didn't when I owned my '99 K3500) so you have to order it elsewhere. I had my truck towed to the local GM dealer after it wouldn't start, they told me the injector pump needed replacement (and it was 3000 miles past the 120K extended warranty GM was using). I had read on the Kennedy Diesel site about PMD failures and ordered a new one through Kennedy, and installed it myself in the parking lot of the GM dealer where the truck was sitting. Got it hooked up and the engine immediately started. I looked sideways at the service manager and drove away. I put mine up on top of the intake manifold plenum, mounted to a heat sink. I put another 70K on the truck before selling it.

I've had my harmonic balancer jump off in the pick n pull parking lot lol

If they were built right the first time nobody would have to do any of this stuff to em . They really are dangerous had my pump decide it wanted to go full throttle more than once on me while stuck in traffic cause its all electronic and not a manual throttle cable ! Chevy should have scrapped the upgrades and recalls to replace pumps and just given everybody a new duramax replacement ! I'm sitting on a 99 with 100k miles and it's had 13 injection pumps put in That's unacceptable ! Usually 1000 each time its replaced ! Not good at all ..
