    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...

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

    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.
