    When you had the head off did you have it dye checked for cracks and checked for warpage?

Blown head gasket will cause this so will a warped head, unproperly torqued bolts on the head, or even a crack in the block.

This happened to me, it was simply the head needing to be magnafluxed, and that showed hairline grooves that warranted a head-resurfacing.....the block can also be checked using this method. http://en.wikipedia.org/wiki/Magnaflux

Did you replace the timing chain when you did the head? The timing chain guides are plastic and they tend to break leaving slack in the timing chain and it rubs the channel behind the water pump inlet even a small pin hole leak can result in alot of water in the crank case.Remove the front cover and check this.

No, This is a warped head or a blown head gasket and I would say the head gasket is more than likely the problem.

91 toyota 4x4 22re overheats on highway, but not at idle.


original issue sounded like thermostat but now that you have lost power i would have to say thermostat, blown head gasket, and warped head

to check thermostat find and remove place in pot of boiling water the see if it opens, then to ice water to check if closes.


the only way i know to check headgasket and head is to check oil and water. oil will have water in it, and water iw have oil in it

Overheating and water mixed in with oil


Absolutely correct. Have cylinder head dye tested and checked for warpage before re-using. Do not run the engine any more than necessary ( into the garage or onto flatbed on it's way to shop) or you risk doing damage to engine bearings.

Radiator keeps over pressuring out of cap


I hate to tell you but most likely your head gasket is blown. But first have your 13 psi cap pressure tested. If the head gasket has blown out in between the cylinder and the water passage , engine compression will enter your coolant and over pressurize the cooling system. This could be caused by a pin hole in the head gasket and that is all. also make sure your head is not warped. The 22re has a cast iron block and aluminum head causing the head to expand at a different rate than the block. causing the gasket to wear and leak. Good luck.

Blown head gasket??? 1992 toyota pickup 22Re


sorry i still think its a gasket problem,or water ports---but without bringing it to yard for me to have a look its a bit difficult and iam in spain.These *** motors use a smaller rad cap with two seals in ,so it can draw the coolant back in on cooling,but iam of the opinion that its drawing in a slight water ingression causing the idle problem.Go on give it a birthday and pull the head off and check its level and not warped ,also the water ports are not dissolved to any extent.

1994 toyota 22re 4x4 pickup fuel injector wiring diagram


the color of the plastic plug does not matter... You will have two injector plugs with white/red and yellow wires - those two go to cyl#'s 1 and 3.
the other two plugs will have white and blur wires.. those two plugs go to injectors # 2 and 4.
