Hi T....Your commentary on how to do a successful basic rebuild is as well said as I've ever read! I wish I'd read it before I did MY rebuild! I believe the Toyota engineers designed your engine to run at 4,000 RPMs ALL DAY LONG.... it won't hurt it to tach it up. Gnarls.
A number of people who routinely rev their 22R engines up high seem end up with rod knocks.
Sounds like you are having early Toyota truck fun! If the fan is rubbing on the fan shroud, you should look to see if the driver's side motor mount is broken.Gnarls.
Been back home for a few days, and the truck has been nothing but great. As expected. Talk about power increase at sea level, I easily lost 20HP when I was up at altitude. At least, that's what my rear end Dino says. I can't describe how great this thing drives, perfect amounts of power and torque. Really makes this a perfect daily driver. The brakes leave a ton to be desired, but I won't clog the Marlin forum with stock truck brake rebuilds, no one cares. Radiator apparently seeps out the bottom, which doesn't make sense considering it's a fully Tig welded radiator. I can do some Tig on DC, I've heard some say helium sometimes works on DC with Aluminum. I'll have to see. Air cleaner did its job wonderfully, I pulled it off the other day to see if any dust had made its way past. Nope, perfectly clean. I'm at about 12,000 miles on the rebuild now, first startup was December 29th of last year. We may hit 15K on the first year of driving the rebuild, that's a LOT of miles for me. What better truck to drive, she always brings me home.
Hey T…..On the brakes, if your truck has the adjustable proportioning valve, you can adjust the leveling bar/lever. I had to make an extended bar to get the valve to open more to the rear brakes. This made a huge difference in braking. I adjusted it to lock up under sudden very heavy braking, which is not good on the streets because once in awhile when the rear wheels locked up, the back end wants to come around. And, the big tires will howl as they skid. BUT… for my rock crawling I needed more braking at rear end. Also, when we did overnight or long weekend runs, I loaded up the bed and the extra braking at rear tires was very noticeable. I also found that ceramic pads for the front calipers work better, even though they tend to chew up the rotors quicker. Thanks for this bit of info. My truck DOES have an adjustable proportioning valve, and I have yet to mess with it. I believe the brakes are just worn, the shoes have material just not a ton. Cracked both the rear drums getting them off the axle shaft, they froze on there good... And I am still running them! I am planning to just do all the brakes on this thing. Rotors, Drums, shoes... Pads... Even wheel cylinders. Well, thats the plan. On the radiator, I’m curious if you found the leak and is it really just poor quality welding or fabrication alloy. Yeah… elevation increase from sea level with that carb’d engine will lose about 4 HP for every 1,000 foot climb. Gnarls.
In short, the offenhauser is trash.
how come this isn't on your thread Gnarly? CB
