I got a bunch of 6.5 parts several years ago, and am finally getting around to installing them on my 1009. I have some questions about assessing engine condition and I am sure I will have more questions as I work through the swap, and will document everything here in the hopes it helps someone...

My 1009 has been a daily driver for 5+ years, and the engine runs fine. Never had any shavings in the oil at oil changes, no knocking while running, or any other evidence of extreme wear. The "Low Oil Pressure" warning light comes on with the key, and goes out immediately after starting the...

I am getting ready to do a 6.5 turbo swap into my M1009 and am starting to collect parts, and have several questions. I've seen Diesel Care in Memphis recommended by Cucvsrus and others on here, and their IP rebuilds seem to run between $450 and $750 depending on what you buy. They don't...

I have a 6.2L in my 1009 that is running, but has low oil pressure (25psi cold idle/45psi cold at 2500 rpm, 5-ish psi hot idle 30 psi hot at 2000 RPM), what seems to be a slow oil leak from the rear main, low power, and just seems generally tired. I've been running the truck like this for going...

I have used NAPA Gold 6096 for my 1009 for years, but recently finished off my last case of them. I'm shopping for some new ones, and there are several options I was hoping to get opinions on. Napa 6096 - probably the best, $21/ea + shipping https://www.fleetfilter.com/filter/46096.html Delco...

My m1009 has a set of Goodyear MT/Rs in 33x12.50 R15 that are about worn out, and I'm looking to replace them in the next few months. That tire is no longer manufactured in that size unfortunately, so I need something else. I drive on the highway a lot getting out to the trails (150-250 miles...

I drive an 1986 m1009, manual swapped, air lockers in both axles. 33x12.50r15 Wrangler MTRs. In 10 years of winter off roading and highway driving in Utah I've never seen a need for chains. Roads are always fine for a careful driver with 4x4, and if the snow is deep and loose enough off road...

Has anybody ever seen a lift pump leak externally? I replaced it in 2018 and the truck starts and runs fine, and I don't have oil getting into the crankcase. There is a small amount of diesel dripping down off the bottom of the engine, and I know the injector pump is leaking (saving up for a...

I'm having a terrible time trying to get the front brakes working on my m1009. Both front calipers won't fully release and are constantly dragging. I just replaced the calipers thinking they may have had corrosion I the bores or something. Also replaced the pads and had the rotors turned and...

This is the 4th 70s/80s GM master cylinder replacement I have done (all on different vehicles, and all work well), and I have never bench bled a MC. Just put it on, connect the brake lines, vacuum bleed at each wheel using a venturi vacuum bleeder, and then take a break for half an hour or so...

I've been looking at F-13 and F-14 in the -20 TM for about 2 hours, but I dont understand what the diagram is saying. All passenger side marker and turn signals on the truck work. The driver side parking light and rear turn signal works, and the side marker light flashes when the turn signal is...

Well, I am not sure what to try from here. I just replaced my thermostat for the second time with another Delco 132-55 (GM 14077122), and the truck still will not warm up above 160F. I have a Vintage Air system with a block off valve in the heater circuit, so there is no flow through the...

I have an '86 K5 with a manual tailgate window. Back in April the window bound up due to a rusted through sash and the pot metal "clutch" that couples the handle to the regulator broke. I used that as an excuse to go through it, and cleaned and greased the regulator, replaced the rollers...

I am trying to rebuild a failed alternator on my M1009, and an having a hard time fining the parts. I bought 2 "rebuild kits" which were allegedly for isolated ground 27SI alternators and specifically listed the M1008/M1009 as compatible applications, but they are missing a lot of critical...

Hi, Has anyone installed the Nostalgic Air A/C compressor brackets along with a 6.5 turbo swap? I have parts from a 6.5 TD in storage to install in the future, but they are out of state so I can't measure anything. I am in the middle of an A/C swap and am trying to decide between the...

I'm getting ready to add AC to my m1009, and figuring out where to mount the compressor. I will be keeping the 24v charging system and adding a 6.5 turbo in the future, so the plan is to build a bracket to hang the compressor under the driver side alternator. I had been planning to use the four...

Hey all, M1009 with the factory dual alternator setup. Truck starts and runs fine. Batteries were replaced a couple months ago, as the old ones were wearing out. They were in it when I bought it and served me well for ~3 years. Now the front battery voltage is a bit lower than the rear and...

I connected the batteries back up on my M1009 this morning, after the truck had been sitting for several weeks for axle rebuilds. When I connected the rear battery I got a small spark, which I assumed was due to a light I had left on or something. When starting the engine the GEN2 light stayed...

My M1009 leaks slowly from the rear main seal, and I want to fix it. I had a 350 SBC with a 2 piece rear main do the same thing, and I ignored it for 10k miles until it suddenly spat all the oil out on the road. So I'm trying to not make the same mistake with the 6.2 in my CUCV. I want to do...

I am looking at a Nordic Air 9k environmental control unit for sale locally. Does anybody have experience with these, or know where to find the repair TMs? I have tried searching for awhile with no success. Here is the data plate from the unit, an info brochure from the manufacturer, and a...
