Blew engine 1 up.
Blew head gasket.
Blew engine 2 up.
Replaced radiator.
Replaced 3 alternators (all caused from washing the engine compartment).
Engine 3 on its way to failure.
Four wheels as good as anything including a Jeep Wrangler.
Slow, slow, slow... but gets you to where your going unless you spray down the engine prior to leaving.
Besides the engine the rest of the truck has been really reliable.
Engine not made for trailer pulling.
Not comfortable.
Noisy on the road.
Bad place for a cup holder (above the radio).
Bumper falls apart if used for towing.
Royal pain in the butt to put differential lockers in.
If used for heavy fourwheeling the engine will fail.
The 22re is a great engine, but with any mass produced vehicle, there are lemons out there, but the 22r/22re has a much better track record than probably 90% of any of the other light truck engines. Although it isn't as powerful, it is much better on gas and much more reliable than the 3vz-e V6 that goes into the early '90s Toyota truck.
If this is true, then you got one an EXTREMELY rare lemon, or more likely, it was completely out of some fluid. If used for heavy four wheeling, or any other kind of abuse you can dream up, the 22r will go practically forever. That is maybe the best engine ever put together.
The 22R-E in my truck was very well-maintained (by me) and suffered only from minor valve rattle. It's a great engine.
I have owned 3 Toyota trucks - all 22ror 22re engines. With the exception of valve rattle they have all been bullet proof! I can relate to the difficulties after washing the engine bay with another vehicle I had. If properly maintained and treated reasonably well, they last a very long time!
I have a 1992 Toyota pickup with the 3.0L engine, and I work at a detail shop in the summer so needless to say I wash my truck a lot, and I have never had any problems at all. Is it just in the 2.4L models that you have this problem?
