Re: How do I adjust ignition timing on a ‘94 4ZD1 Pickup?

Glad to hear things worked out! If/when you decide to pull the distributor, I believe the key factor is whether the crankshaft is moved (engine turned somehow) or not. If it's not, then the marks you've made (with your trusty WhiteOut) ought to make reassembly a snap. If the crank is moved, you'll h...

Re: How do I adjust ignition timing on a ‘94 4ZD1 Pickup?

T he little ridge is a pointer. It corresponds with a mark on the cylinder head. When pointer is in line with the mark on the cylinder head plus the crankshaft is aligned with the 0° mark on the timing cover this indicates The engine is timed at 0° top dead center on cylinder number FOUR. That's rig...

Re: Ethanol gas treatment recommendations?

Update: Replaced the send/return fuel lines, bought a RockAuto roll of 5/16" Gates 27304. I'll use a good portion of it on other vehicles. I have a mechanical fuel pump, so the specs for the hose are ideal. Drained the tank, replaced the filter, overhauled the Hitachi-again-, but alas it still ...

Re: 1985 P'up. Battery light stays on when truck is off.

Plz let us know what it eventually takes to correct this, as I don't think I've ever heard of it before. However, after reading a little about it, it doesn't sound too uncommon. Some fix actions I've read ranged from the instrument cluster (that's kinda vague) to the ignition switch. It's just weird...

Ethanol gas treatment recommendations?

The truck began acting up with no idle below 1800 rpm, stalling, and jerky acceleration. Discovered a gooey gel-like substance in the fuel filter, and the carb bowl had a lot of the same stuff (Flubber?), clogging the primary jet, etc. Proceeded to overhaul the carb. I've learned that this is the re...

Looks like a lot of fun! By the way, could that be brake fluid on the tires (uh oh), or did one of those deer only mark its territory? /R

Re: Hard cold start - possibly down on power - help!

Ref 'Stuck Filter Removal': For spin-on filters, I get stellar results from a 3-jaw wrench; an example is Jegs p/n 555-W270. HarbFrt sells them for about $6. They can fit anywhere, and it's also handy for jar lids. If all else fails, there's always the punch-a-screwdriver-through-it method! /R

Re: 1990 2.3L Air cleaner gasket or replacement air cleaner

Ref the air cleaner gasket/seal, I made one from a length of old engine vacuum hose. Measure the circumference of the opening, add a skosh to make a tight end-to-end fit, split the hosing lengthwise, and fit it in the air cleaner opening lip. Makes a nice, tight, pliable fit around the carb air horn...

I went down the rabbit-hole of a dust boot replacement a while back; do a search in "parts" for "Part # for gearbox shifter dust seal". My sandwich bag fix may raise eyebrows at the Concours d'Elegance, but it works. Your g-box/transfer case should take a little over 4 qts of eng...

Re: New radio installation

Nice work! Do you have a concern about parasitic draw for the clock-memory on your battery? That's always kept me from going this route with a radio, on older vehicles that didn't originally have them. Analog radios seem to have become extinct. I've been using an old portable transistor radio under ...

Re: Clutch/cable problem?

For the sake of mentioning, there's a clutch pedal return spring on the pedal itself; mine's tucked up with the clutch switch plunger, next to the pedal stop-bolt. The p/n shows 8942224750 on this forum's ilcats.ru link. I can't find an image of one, but it's a pretty stout spring. /R

I'm intrigued by "...the odd little metal canister..." in your opening post.
Does this help? /R

Re: Lack of speed on a Diesel 4x4, thoughts?

You could verify what the rear axle ratio is. If the motor was swapped, other parts may have been as well. There's a procedure online for checking it, with a jack and a piece of chalk. I've read about rear ratios as high as 4:55 that will swap into these rigs. /R
