BTW iirc LMC truck sells the replacement seat material. not a cover but the actual replacement fabric if you want to make them look new!

Install the better one on the drivers side.

Here is another link with that is direct to the file. I tried to upload it to the forum but the file is too large. https://www.gmcmi.com/wp-content/uploads/2019/06/Cruise-Control-System-Training-Booklet.pdf

Not sure if this will help, but here is a downloadable book for the GM vacuum cruise control system. https://www.scribd.com/document/440705077/GM-1968-1982-Cruisemaster-Cruise-Control

iirc your cruise module is vacuum controlled. that should be a fairly simple system, but I don't recall if you still have your vacuum pump.

No, I didn't even think about the egg trick. yesterday evening after dropping some black pepper and topping it off it seemed to hold and from the looks of it, it stopped leaking almost right away! I will know for sure after work today, I have been normally getting a small puddle within a...

I added some strip LED lights under the dash on my 93 and tied them into the running light circuit so that they are on when the headlights are on, I always like to see my feet in a vehicle at night. I have them on a resistor so there not at full brightness and set to a blue color so it just...

the under dash light fixtures should be in that area you showed the pic of, if the fixtures are missing, with wires / bulb sockets should be there maybe tucked up in the dash so there not hanging. as for the cluster lights, I always replace them with LED bulbs. next time you pull the cluster...

Well the coolant leak on the 93 has been getting worse. the leak is the timing cover against the block. it's been a week since I had to add a full gallon of coolant and today on the way home I noticed the temps climbing up and hovering just a hair over 210. I let it cool after getting home...

Welcome @MarvinWoodie I would start with checking all of the fuses in the fuse box and fuse links on the terminal block on the passenger side firewall using a test light. once all is verified, then check for power at the back of the alternator. I assume the engine is throttle body fuel...

The term is used in two ways. Water mist injection or water methanol injection. Both are used on diesel engines. A fine mist of water is sprayed into the intake while under acceleration to add power and to help cool the incoming air. There is a science behind it that helps improve efficiency...

Sounds like your about as efficient as you can get. Now you just need to install WMI (water mist injection)

Nice! save on those extra wire and connectors. you never know when you'll need them...

I think with your current setup that's about the best you will see. fuel mileage will change drastically with how much lead is in your foot! but slight changes can be made with proper tire inflation too. what speeds do you normally see in your routeen routes? what size tires are you...

While we had the tank out, I found out why the gauge doesn't work. the brass float seems to have split apart. I tested the sender and it works so there's that. also in doing a little research looking at the tank design and knowing the PO bought several parts from LMC I believe we have found...

Update on the truck. the head is at the machine shop. the guy inspected it while we were there and immediately said with caused all of this. Rotten gas. he said that we needed to pull the tank and to through everything or this was going to happen again. we got back to the house and...

That's entirely possible. I need to also mention to the machine shop that this engine has TBI fuel injection. that might make a difference on valve springs. might need to have them install stronger springs. Also wonder if that would have put additional stress on the press in studs causing...

I still need to clean things up to remove the carbon deposits around the top of the cylinders and clean up the surface, but there is no visible evidence of any valves contacting the pistons. I was really worried about #4 since it showed absolutely nothing on the compression tester. #5 and 6...

Well guys, here it is.... the teardown pics. Intake and exhaust removed Head it off... #1 cylinder #3 cylinder... #4 cylinder... this one had zero compression The Head... #1 on the left Cylinders #1-3 Cylinders #4-6

Wondering if using the weed burner 9000 will work. just burn them down with the torch and smooth it all out. our entire yard is laced with all these oak tree saplings
