@@mikesrandomvideos agree I never leave any vehicle factory I'll fix any potential problem before it becomes a problem.

[@Hatchbackiller]

I've got a 1996 6.5, love it. The only issue I've had so far is the water pump went out at 150,000. But other than that the fuel mileage is great and it starts in any weather. It was -2 this morning. But everyone has their own experience, some better than others obviously, with the huge cult following of people who love to hate the 6.5.

[@mikesrandomvideos]

great engine just keep an eye on that PMD when it goes you need to do the PMD isolator with extension to the left fender, Put a fan on it and no more issues. IF you want more power put in the #9 resistor and put a K and N universal air cleaner right on the turbo and that truck will pull like anything.

[@mikesrandomvideos]

and yes for sure I would take a 6.5 in cold weather over any ford. they just fire right up. My duramax fired up at 3 degrees with no issues first crank. My ford well it took a few times running the glow plugs. then was so noisy I had to let it idle for about 20 minutes.

[@JREACHER1954]

Have a 94 K2500 since new. Went through the usual injection pump replacements (3 - under warranty) and I've done the additional upgrades that increase reliability and will never part with mine. Let the haters hate.

[@Hatchbackiller]

I bought mine used off the original owner, so the pmd was already relocated above the right fender, but it's been great. I had an 82 Scottsdale with a 6.2 and that thing was one of the best trucks I've ever owned. That's what started it for me.

[@Hatchbackiller]

And after watching your video I do want to do the #9 resistor and the new air filter, it makes sense. One of these days I'd like to head stud mine and put marine injectors in it, but that's for another time when I've got more cash.

I have both a 6.2 and a 5.9 12v. They are just completely diffrent engines with diffrent intentions. The 7.3 and the 5.9 where med duty diesels. The 6.2 and 6.5 are light duty diesels. 7.3 and 5.9 came in school busses and dump trucks and box trucks and straight trucks. 6.5’s and 6.2’s came in 1 tons or 1.5 tons at most. Both are great engines but the 6.2 and 6.5 where made for economy and the 7.3 and 5.9 where made for med duty work. All great engines that get the job done. Love my 6.2 for the fuel mileage and cheap parts. Love my 12valve for the power.

The later models 6.0 6.4 OMG not so great. 6.0 is good once you spend 10g bulletproofing. But 10g...come on. the 6.7 has the cp4 pump...Totally trash IMO. at least you can modify the duramax. to the cp3. and in 17 they dropped bosch I dont blame them Denso is better.

Wrong all those engines are light duty diesels. Idk why people try to lie and pretend that the 12 valve is used in semi trucks. All of these engines put out relatively the same amount of power and all are extremely slow

I pull a trailer that is 3500-4000lbs total, which I know isn't much. The PMD was relocated about four years ago and that does indeed make the PMD last a lot longer.

[@supersteveize]

I've got a 97 van with a 6.5 also. The was the guy that I bought it from had put the PMD along with a heat sink in a computer fan up underneath the driverseat. I bought the van with a bad injection pump with 210,000 miles on the van. This was the second injection pump that was on the van before I got it. GM had a recall apparently. I bought a used reman pump and a lot of other 6.5 pick up stuff for $300. I installed a fuel pressure switch that was a adjustable and a couple idiot lights and a fuel pressure gauge so I can keep an eye on the lift pump pressure. I adjusted the fuel pressure switch down so that the incandescent indicator light flickers at 4 PSI. I haven't done a lotta driving on the van it seems to run good and have plenty of power. The fuel pressure switch gives me some peace of mind lets me know if the injection pump will be starving for fuel. Because the fuel is ultra low sulfur now it doesn't have a lot of lubrication. I use either Marvel Mystery Oil or 2 stroke motor oil put into the fuel every once in awhile to keep the pump lubricated. The fuel or oil pressure switch came from Jegs. Installing the injection pump on this van was probably one of the least fun jobs I've ever done in my life. I put new injectors in a while I was installing the pump. It seemed to make sense at the time. Sure glad I did. The van seems to get around 20 miles to the gallon on the highway and gets16 around town. I have problems with the CDR acting weird. I also had turbo booster issues which actually turned out to be a broken vacuum line which I ended up fixing with heat shrink tubing. I've had thoughts of putting a manual injection pump on it and a catch can to replace the CDR. I got to say I really like the van but I sure hate working on it. if the engine craps out I'll probably put a 4bt in it just because it's so tight in the engine compartment with a 6.5.

The only thing is that it’s been sitting for 3 years because the owners son passed away. Is there anything I should be looking at in particular other than the general things to check??

[@davidbrewer8309]

@@TheNinja8000 see if the pmd has been relocated away from the injection pump. Preferable behind the front bumper or on top of the engine with a heat sink. Look for any possible vacuum line leaks. If there's any type of crank knock/ tick... walk away. The 6.5L has a higher diesel knock compared to other diesels. Don't mistake that for crank knock. The oil will probably black... it's just soot. Mine gets black within 1k miles after an oil change so don't worry there. Make sure the lift pump comes on... if it starts hard it might need oil pressure sensor. Drive it for a good 15 minutes and make sure it doesn't overheat... and really just the crank noise. Those were the two big ones. Most other common issues are fixable for pretty cheap. That kind of mileage and decent condition overall $3k-4k would be my upper limit on price.... good luck bud

Since you actually responded, I have a question.. What is the rules on diesels in California? I heard in the video you can't drive legally the 7.3 anymore?????? I have a 2006 Duramax.. Here in Texas, I deleted the EGR, cat, and muffler. They don't even check for emissions on diesel here.

@@dr.fishing5740 We have biennial smog inspections on all diesels newer than 2000 and all original equipment must be on the vehicle. that is what they inspect on all pickups. On small commercial trucks, They now must meet 2010 emission standards as of 2020. So my 7.3 in my bucket truck is no longer drivable after 2020. Must either be sold or apply for a mileage exemption which is 1k miles annually. 7.3 litre in a pickup is Ok and can still be driven if it passes smog inspection.

[@mikesrandomvideos]

I have had one problem with my 6.6 duramax and that is the injectors I have 225k miles. Has more power than my ford and no other issues. They have had some guys say they have problems with the head gaskets but I think usually it is misdiagnosed with the orings on the injectors not seating or botch install on them. They do have newer injectors that dont have problems. All my buddies drive duramax and none of them have any of the F-word issues. After having both engines and working on them both the duramax is easier to repair. I have done the water pump too which is a bit different but much easier than the ford. The only other things that go a bit haywire is the dash gauges, BCM chips can come loose in the conputer which is not hard to replace. I have had 2 duramax. the only reason I got rid o the first one is because my GPS shorted and caught fire it had almost 200k miles one set of injectors, water pump and that is it. Never any oil leaks on any of them
