    Fixing the Truck to Death – time to cut my losses?

    From what I'm reading I think most of these pour in fixes are sodium silicate. SteelSeal claims it is not sodium silicate (sort of) - stating: "Steel Seal is a unique mixture of chemical compounds that have been specially blended to react under sufficient heat and pressure to create a hardened...

    Fixing the Truck to Death – time to cut my losses?

    Drained the radiator and removed the right side engine drain plug. Total coolant removed = 4 gallons. Total coolant capacity = 6.2 gallons. Can't remove the left block drain plug without removing the engine mount - can't get a tool onto it (see pic). I've run it twice since draining the coolant...

    89 Manual says no knock sensor: Section "7" Electronic Spark Control (ESC) This system uses a knock sensor in connection with the ECM to control spark timing to allow the engine to have maximum spark advance without spark knock. This improves driveability and fuel economy and is used on all...

    Fixing the Truck to Death – time to cut my losses?

    It's a 454 = no knock sensor. I didn't know there was a block drain plug. I'll see if I can find it/them in the manual. What little google offers says to look near the engine mounts. Assuming antifreeze acts as a corrosion inhibitor, is there any risk to other components buy not having coolant...

    Fixing the Truck to Death – time to cut my losses?

    Hadn't considered that. Is there an easy method of getting the coolant out of the block? Edit: I suppose I could empty the radiator and run the engine till the steam stops. Heck, engine might run much better once the steam stops - at least for a little while.

    Fixing the Truck to Death – time to cut my losses?

    I don't think there is/was anything wrong with the thermostat. I can't keep it running long enough to get up to temperature with or without the thermostat. The sequence of events WRT smoke/steam: • Noticed heavy exhaust smoke/steam (thermostat IN). Assumed head gasket even though compression...

    Fixing the Truck to Death – time to cut my losses?

    Linestogo can't make fuel lines that will fit better, but are refunding me for the flexlines. I replaced EGR and MAP knowing it wouldn't solve anything. Also removed thermostat so I could get coolant flowing since I can't keep it running long enough to get hot enough to open it. This made a...

    Fixing the Truck to Death – time to cut my losses?

    Linestogo initial response was: “Yes, we know the ends are longer than OEM, but no one else has complained about this particular vehicle set. Looks like it might fit once you get it in.” They are passing the issue on to Engineering and will get back to me. I have time to do this project now and...

    Fixing the Truck to Death – time to cut my losses?

    Dang, I thought I was at the finish line, but the return line from Linestogo doesn't fit. interferes with brake booster vacuum connection in manifold. It's 0.6 inches too long.

    Fixing the Truck to Death – time to cut my losses?

    The pride of accomplishment deserves a photo. Loosened the "P" clip nut blind, laying on top of the engine bay. Removed it from underneath with 2 feet of socket extensions ending in a flex shaft. The plastic tube isn't held in place with anything.

    Fixing the Truck to Death – time to cut my losses?

    Here are a couple pics of the braided TBI to rigid fuel line routing from under the truck driver side. I see a lengthwise slit in the tube that I assume will allow me to remove old and insert new line without having to actually thread them through. I may just cut the old line and see if I can...

    Fixing the Truck to Death – time to cut my losses?

    Progress. I didn’t completely remove the tank. Only dropped it down enough to gain easier access to put the siphon through filler neck hose and remove the old feed and return lines. The new Linestogo fuel lines come with braided stainless flex lines for pump to rigid line connection which is a...

    Fixing the Truck to Death – time to cut my losses?

    I'm no physics expert so I can only comment on my real world test experience. I was testing dead head pressure: Gauge connected directly to pump with no output. Fuel module was not disconnected so I was testing with pump running 20 seconds. Test 1 - 16 psi Test 2 - 16 psi (Confirmed result of...

    If you aren't saying that air has no effect on fuel pressure, then I have no idea what that sentence means.

    Fixing the Truck to Death – time to cut my losses?

    Air is compressible, whereas fuel is not. When air is present in the fuel line, it can be compressed by the fuel pump, which can cause a decrease in fuel pressure. Had to respond to this as it's not a: what weighs more a pound of feathers or a pound of rocks, scenario.

    Fixing the Truck to Death – time to cut my losses?

    The flex line connections under the vehicle have rusty nuts = can't spin the nuts and the rigid return line is rusty that someone repaired with rubber fuel line at some point. That rubber repair is hard as a rock and cracking. The feed tank to filter line (the only piece that's available from...

    Fixing the Truck to Death – time to cut my losses?

    I'll be dropping and siphoning the tank on Thursday. I even ordered new fuel lines = the worlds most expensive fuel lines from Linestogo. Full set from TB to tank = $464

    Stalling, Rough running, Rough shifts threw 22 code, replaced TPS no fix. Ideas?

    Suggest disconnecting fuel feed line to filter and catching some of the gas to see what it looks like. That's how I discovered I had bad gas. I used one of those plastic bubble shipping envelopes to guide the gas to the container - otherwise it just gets all over the truck frame.

    Stalling, Rough running, Rough shifts threw 22 code, replaced TPS no fix. Ideas?

    Interesting. I was having the same symptom right before my truck became undriveable. I'm now 80% sure my problem is separated gas.

    Stalling, Rough running, Rough shifts threw 22 code, replaced TPS no fix. Ideas?

    Considering all the bull I've been going through diagnosing my idle issues, I'd seriously consider siphoning all the gas out of the tank to see if you have any bad separated gas. You may have other issue too, but I'd start with the fuel. Naturally if it is bad, you'll need to replace the filter...

    Fixing the Truck to Death – time to cut my losses?

    Bad gas is one of the items that the repair manual doesn't cover as you drill down the step by step procedures, yet in these old vehicles should probably be the first thing to check.

    Fixing the Truck to Death – time to cut my losses?

    Nicely put. I'm going to use that: HF - Seller of Tool-Shaped Objects. Made the mistake of buying drill bits and calipers from them in the past. I can't complain about their angle grinder or rolling tool storage cabinet though. I can't put a rubber test line in place of the filter as the filter...

    Fixing the Truck to Death – time to cut my losses?

    Just checked the dead head pressure and it measures 16psi with air in the line and 19psi when I purge the air out. This made me say WTF, so I put the GM adapter that comes with the tester back in the line to see if it still read 3psi and it turns out the adapter is leaking. So I replaced the...

    Fixing the Truck to Death – time to cut my losses?

    My sawzall rant is just me getting frustrated - sorry about that. Even if the exhaust was semi-clogged, it's not running long enough to build up any real pressure. At this point it's turn the key - sounds like a normal start and then almost instantly dies. Fuel pressure tested with "T" fitting...
