I have finally found my leak. Rear heater core and all of the carpets were soaked this morning. In the middle of removing all carpets trim pieces and rear assembly. Hopefully this would help.

 

The only way to know 100% if you have water in your oil is to send a sample and have it tested. If its a small amount you may not notice it in the oil until it is to late. if you catch it early you could repair it. you can look at oil and tell if it there unless its a good bit. A test will tell you everything about the inside of your engine especially if you do one every other year or so. You can find them for aeound $25 with shipping. hope you find it

 

Good Job Kiloil......

George--just make sure you keep it topped off until you find the leak. Like you were also saying, these leaks may or materialize when the engine is up to operating temp. I also wouldnt exceed the cooling system pressure rating on the radiator cap. Just pressurize it up to what the cap says.

And--also try getting the motor up to temperature, BE ULTRA CAREFUL and pop the rad cap and then pressurize when the engine is hot--see what you find.

AND--it would be possible that you wont see the leak from the bottom because the bottom timming cover has a small like resevior built into the bottom of the cover. This catches oil/water so it doesnt foul the belt. If you cant find it you are going to have to tear into that motor and find it before you blow the motor.

And like the others have said--that water pump--you have to take a look at it!!

AND--get air tools to remove the crankshaft bolt.

 

Look under the passenger side of your truck by the frame rail. Find the two hard lines that deliver coolant to your rear seat heater. Are they corroded?

I drove the car with the plastic timing belt cover off for a week and found where my anti freeze was leaking from . Using tracer dye and 150 miles later I see very small trace of the fluorescent dye around the water pump housing towards the passenger side... The seepage was so small that the antifreeze would evaporate before it would hit the ground. I think it would only leak when the engine is cooling down/heating up - two different metals expanding and contracting at different rates causing the oem gasket material to fail.

However, it not bad for a water pump gasket to fail after 185k miles... To think the water pump bearing and seal is still holding!

And to think I almost gave up on it!

 

Don't forget that the OEM pumps on the earlier years was just FIPG. Then Toyota redesigned the pumps because of the leakage problem and the new pumps came with a metal/rubber gasket. So consider yourself lucky if one of those original FIPG jobs lasted that long.

 

I hate to jump this thread, however I need help ASAP.
I plan on replacing the head gasket in my 93 and will be using an Altrom gasket kit.
Anyone who has info on the gaskets, I would love some feedback.
Thanks,
Kurt
