Question about 1994 Toyota Pickup

Changing the Head Gaskets

I have a 1994 toyota pickup truck (22-RE) with a blown head gasket. I have removed all hoses, electrical connectors and bolts. I can lift the head and intake manifold (still connected) off of the block. The only thing keeping me from finishing the project is a wiring harness. It runs from the Right (passenger) side of the truck through the intake, splitting off to the injectors among other things, and back into the firewall on the left (drivers) side. The intake will be very difficult to remove so is there any way of removing the head with the intake still attached? Any help would be greatly appreciated. thanks

Hi Dirk, its easier to remove the harness, i gues your problem could lie with disconnecting the injector connections, to disconnect them there's a locking stainless-steel ring which needs to be moved halfway on one side and then the connector pulled out. and also check for a large connector that can split the harness.

  2. Remove the spark plug wires. Disconnect the PCV hose.
  3. Remove the four nuts and grommets located on top of the cylinder head cover.
  1. Remove the cylinder head cover and the cover gasket from the cylinder head.
  2. Discard the gasket and replace with a new one.
To install:
  1. With a wire brush or gasket scraper, remove all the old gasket material from the cylinder head and the cylinder head cover gasket surfaces.
  2. When the cylinder head surfaces are free and clean, apply beads of sealant to the cylinder head in the locations shown in the accompanying illustrations.
  3. Install the new cylinder head gasket in the cover. Make sure that the gasket seats evenly.
  4. Place the cylinder head cover with the gasket onto the cylinder head.
  5. Install the four grommets and nuts. Uniformly tighten the nuts in several passes to 17 ft. lbs. (23 Nm).
  6. Connect the PCV hose. Connect all removed vacuum hoses, connectors and electrical wiring. Connect the negative battery cable.

I have already checked the heater core........that is not it. Could it be ingesting water through the part under the throttle valve that has two small water lines running in and out of it?


is the motor the 3VZE, if so replace the head gaskets, even on the 22R motor, it sounds like it is about time to replace the head gaskets, usually about every 100,000 miles it is time to replace the head gaskets, is the coolant getting into the cylinders and burning and white smoke that smells like antifreeze coming out of the exhaust?

Check for bubbles in the radiator when the engine is running,if bubbles are evident then head/head gasket is at fault. Also could blocked 8mm bypass hose from thermostat area.( also check the basic like thermostat operation and radiator for both internal and external blockage.

1994 toyota pickup blown head gasket. is that an easy fix? can i do it in my school autoshop and or driveway?


So the first question is ... is it really a blown head gasket? Could also be damaged head, block, etc and the timing chain can wear through it's housing and allow coolant into the oil. If it is a blown head gasket then why did it happen? Is the head warped, coolant passages corroded, or ?? Here's link to
a '93 manual to give you some idea what you're dealing with. http://personal.utulsa.edu/~nathan-buchanan/93fsm/ Can you replace the gasket in shop or driveway ... depends on what sort of
complications you run in to. You may want to have a valve job done while you're there, maybe
time to do the timing chain, etc. Give it a try.

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

Water in all 4 cylinders


oooo, not good, Head needs to be checked for cracks. After a failure, REMEMBER the gasket is not the culprit, or cause, but a victim. Head usually needs to be fly cut, if not cracked. Take head to machine shop for checking.

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.
