How much Toyota goodness is in the engine? MLS head gasket? DOHC? VVT-i? Oil squirters? LOL. Autocorrect made oil squirrels! That’s a new one on me! Does ih8mud have a Squirrels-in-a-Toyota-Engine video?

Gasket set was Toyota.
No vvti.
No oil squirter.

Congratulations getting it running! Will it make an appearance tomorrow at the meeting?

Pretty sure he headed to Utah yesterday. Pappy don't mess around when it comes to a test drive.
 
Back in civilization and the usual Moab diner fix.

Back at it. Today was AC day. I worked on cobbling AC hoses, and installed a different high pressure line. My 22RE had the service fittings on the compressor. The new compressor doesn't have service fittings, so I needed them on the line/hose. The setup from a 1988 truck was the ticket. I just needed to adapt them to the manifold on the compressor. Hoses were mocked up so I can take them to Action Hose on Monday and get real hoses made.

Another project was to swap out the supercharger pulley for a smaller pulley. The boost is a bit conservative (around 4psi), but that was on purpose. I didn't want to install a 5th injector and controller. I'm very happy with the power, but a tiny bit more boost couldn't hurt. I think I added 20hp. I also installed larger fuel injectors going from ~298cc/min to 325cc/min. When I can get it into the budget I'll install an air/fuel gauge.

Last improvement, I decided to remove the balance shafts. LC Engineering made a kit to do this. Unfortunately, it created another problem that will get resolved next week.

It's one thing after another.

1. Before Lockhart I was getting a knock sensor code, but only in the morning. Once the engine warmed up it went away. While Robbie had the engine I had him install an aftermarket sensor (couldn't get the OEM, at the time). I drove back from Scottsdale, and in Gallup the CEL came on. While Sandia Toy was dealing with the oil pressure (next) I had them install an OEM sensor (not a Denso product, BTW). I drove it for two days, no problem. Confidant, I packed for Ouray ... and I didn't make it out of town. The issue wasn't the sensor, or the circuit. It was the ECU. Replaced the ECU and life has been good. I actually bought two.

2. Oil pressure. When Robbie did the balance shaft delete it jacked up my oil pressure. Like 100psi jacked up. LC Engineering said folks run that all the time after deleting the shafts, but they did recommend removing the outer spring on the pressure relief valve. I did that, but pressure is a tad lower than I would like (40psi@3000rpm). After doing some homework I'm going to install the spring from a 2RZ (2.4L), which doesn't run balance shafts. The spring I'm running now is the inner spring (of two). The 2RZ spring is the same diameter as the 3RZ outer spring, but half way in height between the 3RZ inner and outer spring.

3. . I did make it to Ouray for one night. The truck runs great. I wanted to drive up the two passes between Durango and Silverton. I did need to shift into 3rd on the 6-7% grades. But, I was keeping up with traffic in front of me, and I wasn't holding up traffic. On the open road this truck is shift into 5th, and forget about it. I've owned this truck for 36 years and I'm having to relearn how to drive it.

3. While Robbie had the truck I had him get rid of the cable heater valve and install a servo valve from Vintage Air. He also decided to remove one of the molded heater hoses and replaced it with generic heater hose. Now I don't have heat. I've confirmed the valve is working. I think their might be a kink in the hose. I can't see it so I can't tell what is going on. I need to remove the starter to see the hoses.

Sweetness, glad things are getting sorted out, all be it slowly! Is it time for a cruise control or a bike shift lever cruise control?

I was looking at the cruise setup on a 92 4R yesterday. Not sure how I could make it work.

back in the day, I think I used a 10 speed bike shifter to control the throttle plate as a college kid cruise control. I attached it to the shifter and it worked a treat as a hand throttle while working the clutch and brake pedals.
 
Something a little bit more fun ... and easy. I made a bracket to bolt down the air box a little better. To make this box work I had to cut off two of the mounting points. It's also attached using one of the mounting brackets under the fuse box. The bracket I made holds it down nicely from the front. The two bolts in the box are attached to rivet nuts made for plastic.

Fixed, thanks to Ryan. Apparently the heater slide on the dash controls two valves. The heater valve under the hood, and a blend valve under the dash. Solution was to move the slide to heat.
 
I am in the vicinity! Yesterday I came up US191 from ~Alpine,AZ to Blanding,UT.
