    This does not look good

    I’d drain the oil, wire brush and sand all I could, spray brake clean to wash it into diff case, clean out case and add new oil.

    Stella, the 6.9, needs a/c

    If you mix r134 components with r12 components, most likely you’ll have to make custom hoses to overcome the thread differences in the two. If your going to use newer r134 evaporator you’ll need the same year hose set and condenser.

    Injection Pump Issues and Adjustment Procedure

    If you do try adjusting the timing, only adjust with the motor off. Tighten the bolts between adjustments, don’t try to leave loose.

    Vacuum pump pulley.... Anyone got one for sale?

    Another thought, for the people who have changed from v belt to serpentine. Did you change the vacuum pump or just the pulley?

    Vacuum pump pulley.... Anyone got one for sale?

    I would get the dorman 300-700 and compare it to yours. When you look at the vacuum pumps for the different years the difference seems to be the nipple orientation of the pump. i put a 1996 pump on my 1993 when I had it and the difference was the 93 mounting holes were smooth and the 96 were...

    Stella, the 6.9, needs a/c

    93 was r12, 94 was r134. They used the same compressor but different thread sizes on the lines. Look at the hoses to make sure fittings are compatible with your 86 evaporator and condenser. I think 93 lines should be the right fitting.

    Stella, the 6.9, needs a/c

    Look at the two compressors. I believe the hoses mount differently between the two.

    1992 E350 7.3 newbie trans questions

    if you stay in 92 year for solinoid you’ll be ok with the E4od you have. Look at the solinoid plug, is it the same as the plug on the van?

    1992 E350 7.3 newbie trans questions

    You need to figure out what transmission you have. 89 is a one year. From there 90-91, 92-94,95-98, with 96 being another odd year. You should be able to use the one you have if it’s diesel by putting in correct solinoid pack.

    6.9l non-turbo/no fuel getting to filter

    Is your truck running right on one tank and not the other? It may be the fuel selector valve or just crud from a 30 year old fuel tank. I’m getting ready to pull rear tank on mine. Driving on rear tank and saw fuel pressure going down until it stopped running. Changed tanks still low pressure...

    6.9l non-turbo/no fuel getting to filter

    Most likely fuel restriction from tank. Disconnect fuel line into fuel pump. Replace with line placed in 5 gallon can, see if it changes.

    I did mine recently. I had to loosen motor mount from frame (left nut on) and jacked it up an inch or so, still tight but came out.

    Sounds like it may be the oil cooler, here’s hoping it is. I thought you were hear a drip into to oil pan with oil in the pan.

    BILLOWING white smoke

    If oil cooler was leaking I don’t think you would hear a leak being it is mounted so low and would mix with oil in the cooler. I think low air pressure in glow plug holes would tell you your cylinders condition as far as cavitation. Test each cylinder at top dead center and bottom dead center...

    I wonder if the front cover behind the water pump could have a pin hole in it?

    Does the oil you drained out have a fuel smell to it? After setting is whatever is in it settling or separating from the oil?

    BILLOWING white smoke

    I wonder if it’s such a slight coolant leak that the oil (over 200 degrees) is causing it to steam into the ventilation of the engine.
