I just installed a long block 22RE into my 94 toyota 4x4. After completing the intstall i ran the engine for about 30 seconds then shut it down to double check for leaks. I found that the block was full of water/antifreeze. I have no idea what year model the long block was or if it even makes any differance. I am pretty sure I have all the hoses in the proper places,but I am affraid I may have missed something when putting the timing cover on and every thing that goes with it.
Can anyone think of any reason I am getting water in the oil?
Water in the oil usually comes from a head gasket problem (leaking gasket, improper head torque, incorrect gasket); a head problem (warped head, improper head torque, incorrect head), or a cracked block.
Hopefully I have something hooked up wrong or used the wrong gasket somewhere, but the first step is to call the company where I bought the rebuilt long block. The block came with a gasket set and I have a water pump gasket and timing cover gasket left over. I know I installed the gaskets for those items. My question is why did the kit come with two gaskets for the timing cover and water pump? Is there a difference between some toyota engines?
I didn't compare the two water pump gaskets. I wasn't aware there was two in the set until toward the end of the install. I remember nothing standing out as odd when I put the gasket on so I really don't think that is the problem. As far as I can
I contacted the company that provided the long block and they have requested that I bring the timing cover so their tech can look at it. I believe they are suspecting the common problem where the timing cover is worn from the chain rubbing against the cover. I am certian that is not the problem, but to make them happy I will bring it up there. I am debating if I should bring the intake manifold with me when I bring the timing cover and let them look over it at the same time.
If the timing chain rubbed on the block or cover because the tensioner was bad, the damage should have been noticeable when doing the work on the chain and water pump.
You can take the intake manifold as well, but I can't imagine how it could be related to the problem with water in the oil. As you eliminate possible causes, the remaining clues seem to point to a head gasket problem. It is probably worth your while to check on the head torque.
The first thing I did this evening was to put water back in the radiator with the oil plug removed from the oilpan to see just how bad the leak was. I had a steady stream of water flowing out of the oilpan. I can't see how a bad gasket seal would allow that much water to leak by.
I went ahead and pulled the timing cover, water pump, and oil pump. All the gaskets were correct and installed properly. I don't know why the gasket kit had extra gaskets, but I am not complaining now :-)
Thinking out loud: How does the water enter the head? Through the intake? What would happen if I put water directly into the thermostat inlet (the thermostat is removed)....where does it go? If I plugged all possible ports behind the timing cover and filled the inlet with water I should be able to eliminate the timing cover...maybe...I think I will go try that. While I am at it I will take your suggestion and check the torque on the head bolts.
By the way, you can't imagine how much I appreciate your help with my problem. It is nice having other opinions and suggestions to work with.
With the three possible ways water can enter the timing cover and water pump plugged I filled the block with water...(timing cover removed)...No leak. With the timing cover installed and water added to the radiator the leak is there. That points to either improper gasket application or a dammaged timing cover. Would you agree?
My timing cover has no visible signs of wear, but i will bring it up to the shop to let the tech check it out. The only possibility of dammage would be a crack in the cover not visable to the eye, but I don't see how that would allow that much water to pass. I am thinking I hosed up on the gasket application :-( On the bright side...if that is the problem I will not have to buy a $200 timing cover :-)

*************
Coolant enters the head through the block. There is no coolant in the intake manifold.

************ I imagine some of the water would flow into the radiator, the rest would flow into the block.

************ Just for grins, grab the crankshaft pulley (if installed) and see if there is any fore-aft play in the crankshaft. If there is play, check to make sure the crankshaft thrust washers (horseshoe-shaped spacer washers) have not fallen out into the oil pan. Excessive crankshaft movement might have damaged a seal or the timing cover itself.
******* When I removed the pulley to pull the timing cover there was no noticable play. In fact it was harder to remove this time for some reason than it was the first time i pulled it. The washers are still in the shaft.
********* Even though the thermostat is housed on the intake manifold, no water flows through the manifold? There are two pipes that bolt to the intake manifold. One channels exhaust and the other...I thought...channelled coolant (goes to the heater).
**Another Topic** What should I use to clean the white foamy oil/water from the head before installing the valve cover? Would WD-40 do a good job due to its water displacement qualities?
Now you have me thinking... It has been a long time since I looked at a 20R so I can't recall the head and thermostat setup. That said, I'm still pretty sure that coolant is not circulating through the intake manifold
I took the cover to the shop this afternoon and was told it was fine. Brought it home and tried to mount the cover and noticed it didn't want to sit flat on the front of the motor. After a few minutes of evaluating the situation I found the reason for my water leak. There are two tube alignment sleeves that are pressed into the block. When I swapped the timing cover over to the new engine one of the alignment tubes was stuck in the cover and I didn't notice it. It just happened to be the one located next to the water inlet for the block. Now I just have to put it all back together and cross my fingers. Hopefully I will have it running by the weekend.
