I'm serious Louis. I know how it is to be "down on your luck" with your truck(s). Both mine are out of commission right now, and have been for a bit. Really miss driving them. The K-5s rear main is leaking all over the flywheel, which can nuke the brand new clutch. The 96 needs batteries...

I'm going off the OBS truck in my garage. GM must've done this one differently, because the oil cooler is definitely on the colder side of the radiator. I feel the external oil cooler was added because the radiators were not as large, or as efficient in the GMT-400 truck. I"ll measure both...

a blocked orifice tube would really put a damper on A/C performance. If the compressor was replaced before you bought it odds are it fail and puked a bunch of metal into the system. If the original accumulator is still on it, odds are the orifice tube wasn't changed either. It is a PITA to...

If this were true wouldn't companies like Banks and ATS have added an air to oil cooler in with there several thousand dollar turbo kits? They built the oil lines for the turbo supply so logic would have it that they would've supplied an air/oil cooler that would've probably just connected to...

I can tell you that without the auto trans in my K-5 it ran cold unless i really got on it. Then it would just touch 200*F before the 195* stat opened and the temp dropped like a rock down to about 175* or so on the gauge. With the auto trans it always sat just under 200*F, but that trans was...

if you need a set of 6.2 style oil cooler lines i've got a full GM set(including the aluminum lines that go in front of the rad which are still a dealer only part). No evidence of leaks either. Also have a few 6.2 rads here if you want to borrow one to test fit it. That way if it doesn't...

air as in compressor? ~80-90 gallons at 150 psi work? The compressor is slow in it's old age(all original save for the oil and from the '40s or '50s) but it gets there.... eventually anyways. :hihi: Takes about 15 minutes to fill the tank from completely empty but it'll run air tools all day...

Louis, If you decide you want to do the headgaskets at some point let me know. Perhaps if you can get the truck to my place in southern CT and we can get a few more local members to help we could probably have the headgaskets/studs done in one day if you bring all the parts/gaskets with...

Glow plug time should be handled by just the controller. It's an "all in one" setup with input from the "start" wire going to the solenoid from the ignition. High idle/cold advance are controlleb by the sensor in the passenger side rear of the head. This "sensor" is an on/off switch that's...

60 times per minute at 6,000 rpm? That sounds awfully slow honestly. Here's a very slow motion video of a valvespring at 7,000 rpm in a Nascar(i guess) engine. http://www.youtube.com/watch?v=i_NpzU4pGjc

They did exist. It was a very rare engine. 4.3L V6 diesel. It was in the smaller cars around when the 5.7 V8 diesel was in the bigger cars. You want even more rare, try finding the near impossible to find 4.3L V8 diesel. Yes there were both 4.3L V6s and 4.3L V8s. Here's an old ad...

There's at least one good head on my spare 6.2 in the storage shed. It'll need a good cleaning but i found no cracks when i pulled that one. The other side, hell if i know. It could be ugly as hell, perfectly fine, or anywhere in between.

94 the tank is pressurized. It's the surge tank style. At least the 94 i did the top end rebuild on was. The old style(which i prefer) seems to have died with the mech injection 6.5s in 93.

Sounds like when the optic sensor took a dump in my 96. Real long crank times with lots of coughing, catching, and stalling. Once it did start it loped like crazy, blowing smoke from the pipes. High idle switches didn't work. It would stop the loping idle once i touched the go pedal...

With the Tygon fuel return lines you'll need plenty of force to get them onto the injectors. A tip from the guy who came up with the Tygon return line idea, use a little silicone spray on the lines right where they slide over the barbs. The Tygon line was originally suggested to me a few years...

I dunno Kenny. IMO the inlet to the filter housing(pre-filter) base on the N/A is too small. They almost doubled the size of the opening on the GMT-400 trucks with the 6.2. Also the air silencer on the square body truck really necks down internally. Again the GMt-400 6.2s had a larger...

i'd re-use that fuel heater. It's very simple to hook up. Just trim the fuel lines a bit with a pipe cutter, double clamp the hoses, and you'll be all set.

I can tell you i love my Heath tune. My 96 you saw in the Southington C&E parking lot that day has been running a Heath GL4 for a good while now(going on close to 3 years). I've towed with it before. While it doesn't get hot, i also don't pummel the accelerator either. I know my limits and...

When i built my setup as i was swapping over to the Banks turbo kit i installed a Holley Blue LP right at the joint behind the doors that BBB82 spoke of. I used a tubing cutting and cut about 3-5 inches out of the lines of either side then used compression fittings to re attach the little...

Infinite resistance on the glow plugs would tell me they are toast. Any good glowplug i've seen is ~0.8 to 1.0 ohms. Wellmans have a mixed history. They used to be awful. THey'd swell and burn out with normal usage(nothing over factory GP time) in less than a year. Some swear by them, i...
