Vehicle Mods & Repairs

I picked up my rebuilt Toyota Land Cruiser 3FE short block

Today I picked up my rebuilt Land Cruiser 3FE short block and head from the machine shop.

Now comes the cleaning, inspection (and buy new parts) and reassembly process.

I need to go buy a small parts washer to make the job easier. Probably Harbor Freight for me.

I’m going to replace all the hoses, belts, thermostat, etc while it’s apart. I noticed that my radiator appears to be leaking so that may need a rebuild. Who knows what else I’ll find during the inspection process.

No estimated time frame when it will be done. I know I’m tired of being a one vehicle family.

Here are some photos of the short block and head.

Increased Fuel Economy and Power for a 3FE Powered Toyota Land Cruiser?

Brandon over at olympiafj60.net mentioned to me on the Whiskey Dick trip about a thread over on ih8mud.com in the 60-series forum on an adjustment that can be made to the Toyota Land Cruiser 3FE engines. There happens to be some type of fuel regulator on the fuel rail near the firewall that be adjusted. People are reporting increased power and even better yet, increased fuel ecomony.

You can see the thread at What the deuce is this thing?.

Well I went ahead and popped the plastic cap off and tightened the screw a couple of turns. Initial impressions while driving around my house seemed to be an increase in low end torque (a very unscientific approach).

I now need to take a test run over Snoqualmie Pass to check against my baseline mpg of 13.4 when traveling from Federal Way to Ellensburg, Washington. Hopefully, I’ll have a little more power on the climb to the summit. When I have the data, I’ll report it back here.

Thanks Brandon for the tip.

FJ80 Land Cruiser Starting Issues

Since I’ve had my Toyota FJ80 Land Cruiser, I’ve only had to deal with a few electrical issues, the Center Diff Lock, the Window Actuator Motor and the Fusible Links from the battery. The first prevented the transfer case to lock up in four wheel drive, the second prevented the window from rolling up, and the third prevented the engine from starting.

Now that I’m a year into the ownership of the Land Cruiser, I’m onto my fourth wiring issue. The engine will simply not start. It started last Thursday when I made a run over to the Cle Elum River near Salmon la Sac. I had one episode where it would not start for about two or three minutes and then it started up fine for the the rest of the trip. On Saturday, it happened again, this time in the grocery store parking lot. This time it would not start until after about ten minutes of trying. Finally, this morning (Monday) when getting ready to leave from work, the little tractor motor would only spin and would not fire up. Of course, this was accompanied by record rainfall in Western Washington. Perfect timing.

Toyota FJ80 Land Cruiser Storage/Cargo Box Build

Having one successful storage box build behind me for my old Jeep YJ Wrangler, it was time to build a storage box for my Toyota FJ80 Land Cruiser. The storage box I built for my Wrangler was very simple. It was basically a box with one very large divided drawer that was bolted into the cargo area in place of the rear seat. In the storage box, I was able to store and provide easy access to all my tools, spare parts, recovery gear and spare fluids. Having all the above gear stored in a storage box allowed me to carry additional stuff (tent, sleeping bag, food, cooler, clothing, etc) on top of the storage box, basically doubling the cargo space. Gone were the days of having everything piled on top of other stuff. With the storage box, with a little creative packing, I even had room for my dog to ride in the back.

I purchased my 80-series Land Cruiser to be able to carry my family, my dog, and my adventure gear. The only way that this was practically going to happen was by building a storage box for the back of the Land Cruiser. In addition to the extra storage capacity, my needs list included an interior sleeping platform for my solo camping trips as well as having a place to install an auxiliary battery for my FJ80. Unlike the newer models (1993-97) of the 80-series Land Cruiser, there is no easy way to install the second battery on a 3FE powered (1991-92) FJ80 without heavily modifying the engine compartment components.

Troubleshooting the Toyota FJ80 Land Cruiser Center Diff Lock (CDL)

When I purchased my 1992 Toyota FJ80 Land Cruiser, the previous owner informed me that the four wheel drive system did not work. I knew the transfer case was a rebuilt unit so I figured it would be something simple such as a switch or a relay. Little did I know that I would spend hours trying to troubleshoot the problem. Hopefully this article will walk you through all the diagnostics needed to check the complete center diff lock (CDL) electrical system so you can figure out the problem much faster than I did.

You might ask, why did you spend hours diagnosing the problem? My answer is, I don’t like to spend money replacing parts when the part being replaced was not the problem. I’ve been a victim of paying people to do just that. Never again.

As in all repairs on the Land Cruiser, you should purchase the factory Toyota Repair Manual and the Toyota Electrical Wiring Diagram for your specific year of vehicle (order the factory manuals at techinfo.toyota.com). A Chilton’s or similar service manual won’t cut it when you are diagnosing specific issues. Invest the money in the factory manuals. It’s worth it if you (or your mechanic) does any diagnostics or repairs on your Land Cruiser. Purchasing the correct manual will pay off only after a few repairs because you will be diagnosing problems and not throwing parts at the problem until it is fixed. The reference for this article was the USA version for 1992 model year Toyota Land Cruiser. Even though there are similarities between all 80-series, there are differences between the various years of Land Cruisers and world markets so be aware of this when making repairs to your Land Cruiser.

Toyota FJ Cruiser Wheels on my FJ80 Land Cruiser

Toyota FJ Cruiser Wheels on my FJ80 Land Cruiser

Ever since I purchased my Toyota FJ80 Land Cruiser, I knew I wanted to replace the factory Toyota 15 inch alloy wheels and 31/10.50 BFG AT tires with larger tires and wheels. The primary reasons for wanting to complete this upgrade included:

• The “C” load rating of the 15 inch tires were being pushed to their limits with the weight of a fully loaded and accessorized 80-series Land Cruiser. I didn’t want to trust them very much longer on a 6000 pound vehicle.
• There are very limited tire sizes that will fit a 15×7 wheel. I wanted to run narrow 33 inch tall tires.
• I wanted to increase the ground clearance by a inch or more. Every inch in the vertical direction helps with a 112 inch wheelbase.
• The 31/10.50 tires looked very small in the abnormally large wheel wells of a 80-series Land Cruiser running the medium weight Old Man Emu (OME) suspension. Even my wife thought the tires looked small.
• In the future, I want to install a full float rear axle from a later 80-series Land Cruiser which requires a minimum of 16 inch wheels to clear the disk brake rotors and calipers.

With that in mind, I was planning on eventually acquiring an inexpensive set 16×8 black steel wheels and purchasing some narrow 33 inch all terrain tires to fit. My plan was to hold off on the tire and wheel purchase until I had the opportunity to regear my axles from a 4.11 to a 4.88 or lower ratio.

Toyota FJ80 Land Cruiser Rear Door Window Regulator Repair

When I purchased my Toyota FJ80 Land Cruiser, I knew there issues with the power windows. Except for the drivers door, all the windows rolled up and down, not perfect but they worked. Then one rainey day last Fall, I rolled down the rear door window and pop, the window would not roll up any more. Luckily, I wasn't too far from home.
