Thought I would start a thread and try to keep all my stupid questions in one place.
I just bought a LJ78 because I need another project about like I need scurvy.
1992 LJ78 with 179k kilometers. Auto trans. LWB.
I will be doing all the EGR removal , fuel tweaking and most likely intercooler on this. But, first I want to establish the maintenance on it. And, I won't tweak a diesel until it has an EGT gauge , so that will need done.
Front swivels are a mess. So, Kurt helped me out with an entire kit to rebuild the front hubs. I am retaining the auto hubs for the time being as they work. If they give me trouble down the road I will dump them for manuals.
Truck has a touch of death wobble at about 50mph. Tires aren't great. So next project will be front end bushings and new shoes.
Now the stupid questions.
Truck is a hard start from cold. Glow plug indicator pops on for maybe 2 seconds regardless of engine temp. I have seen several threads about testing the plugs, relay, ect, so I will get to that in the next bit. But ,my question is; how does that light function. Does it stay on for different interval at different times. I probably just missed it, but couldn't find that answer.
Next is the idle adjustment knob. Mine just turns a bit. CW snugs it down and seems to raise RPM a bit. CCW losens and drops RPM slightly. How much variance is that designed to give? I am seeing maybe a 50-100 RPM change.
As you can see in the background of my picture, I have a far more insidious hobby than Toyotas. Hopefully Toyotas can replace that hobby after over 20 years. Not sure it will take but I am hopeful.
