the 2500 with 454 should tow but will be a gas hog. will still need some upgrades like a trans cooler, but should come stock with a 4l80e. even better if equipped 4x4. if looking at it to buy, be sure to look at the tag on the drivers door frame and see what it's setup for stock as for...

I learned from work to use air first, then water. the muck out there at my work turns into an adobe brick when wet!

Another tip... do NOT use the GM orange DEXCOOL !!!! go back with the old school green antifreeze, and these diesels do not need any PH modifiers like the newer diesels need. those additives actually do more harm than good on these old IDI engines. the GM dexcool gets very corrosive, I...

While your in there with the thermostat, when was the last time you flushed the cooling system? I mean pulling the block drains, removing the coolant recovery thank and rinsing it out and possibly even going as far as pulling and flushing out the radiator? I wish I had a video of when I...

iirc dual stats didn't come out until 97. there is a one of a kind much saut after 96 style, but anything older should have a single stat with a block-off plate like the ones in the link I posted above.

is your rig a single thermostat or dual? if it's like mine with the single thermostat here are the part numbers for the 180 and 195. https://www.rockauto.com/en/moreinfo.php?pk=4484214&cc=1034558&pt=2200&jsn=655 https://www.rockauto.com/en/moreinfo.php?pk=4484472&cc=1034558&pt=2200&jsn=656

What trans is in your rig? if it's a 4l80e then itll be an electric speedo, 7r400 uses cable driven. I have one of those GPS speedo's, they work decent but they take a few minutes to connect and register speed when turned on. they are also nice to use to calibrate your speedo once you get...

I would not do that on a running engine! taking another IP and doing that in a controlled environment is much safer! I can't remember but I think some john deere tractors use a similar DB2 IP but is setup for a 4 cylinder engine. really any IP that produces those pressures and can be...

engine sounds good, but in your tests I would question the spray pattern of #3 and #7. #4 and #8 is what you want to hear and see from all of them especially from new injectors. I have always thought about rigging up an old DB2 IP, doesn't matter if it's off a 4 banger tractor or from a...

I agree, probably need to have those injectors leak down tested. I can do it for you, but it would leave your rig down for a bit unless you have a spare set to have setup and then swap them out. when it's doing that, if you give it a little RPM from the go pedal, does it fog the area for...

Well spent the day playing in my cad software on my pc along with doing other household duties in between.. made several iterations of this stack-able gauge pod and now I think we have a winner! I did a custom base to try and fill in as much of the gaps on the pillar as possible while still...

I'm not sure they are available anymore, others can verify that. if the hose is there and just plugged off, iirc that T valve is just a brass drain valve with one end having 1/4" hose barb for the hose coming from the FFM (fuel filter manager). the other end is open, the original had another...

Well, I would say go ahead and pull the injectors, mark each for which cylinder they came from. test them, pull them apart, inspect, clean, and retest. I use a ultrasonic cleaner I got off the jungle site to clean them. use some water base solvent like ZEP 505 cleaner. if you need shims I...

Maybe I mis-read something, I was looking at your trans input and output speed. next time your out n about, pay attention to your tach and speed and see what they look like. your most likely have 4:10 gears for hauling. my 95 has 3:73 gears, 265-75-16 tires and I get about 2200ish at 70mhp...

Welcome @Boblaw66 when under load are you getting any smoke from the tail pipe? could be not getting enough air from the turbo or clogged air filter. lift pump should be providing 8-14 psi continuously to the IP. the factory GM lift pumps are garbage for keeping up with the demand of these...

@Will can tell you all about engine temps on these rigs! you want it to stay under 200. your risking cooking cylinder #8 piston and rings. There is a pipe plug in the head near the #8 cylinder, pull that plug out and install you a mechanical temp gauge there to keep in the cab. run a...

look at your engine coolant temp, 211 is in dangerous territory for these engines! also 2700~ rpm at 57 mph is where your MPG's are going! what is your rear axle gear ratio and what size are your tires? I assume you are running a 4L80E trans.

Running a spring on the waste gate might cause teh PCM not to be happy. but in your snapshot there were no codes set. the Turbo Master which is a bracket and spring setup might help you set the boost pressures under load and help keep the boost down low when cruising with the old injectors...

you have to subtract the boost pressure (map) from the barometric pressure (baro) to get the actual boost pressure on these rigs. he's only running 10.95 PSI from the turbo.

My son and I put together a small print farm in the spare bedroom over the last few months. The work area is a bit of a mess right now with my most recent (used) printer being overhauled (far right in photo), but this is what has been keeping me occupied and off the forum for a bit. I had...
