Topic: How to check to see if a motor is hydro'ed?

Anybody know how to check to see if a motor is hydro'ed?  It's an 84 4Runner with probably 200K on the clock.   We haven't tried to turn the motor over yet since the guy I bought it from said it runs barely and really rough. I didn't really want to ruin anything like the crank if it was hydro'ed.

I pulled the dipstick and the oil was black but no signs of water. My dad and I pulled the first spark plug and it looked great as well. The coolant looks fine, nice and green, in the raditor. Any ideas???

Pull all sparkplugs and crank the thing and water will pump out the plug hole.

yup, what he said.

If this thing has been sitting outside in 100 degree weather since I bought it at the end of June, will the water still be inside the engine?  Can it be evaporated just sitting there?  I plan on pulling the plugs and cranking but haven't gotten the chance to work on it yet.  Stupid landscaping my backyard taking all my time

The plugs wil tell the story pretty well.  If there is/has been much water int he cylinders you should be able to tell pretty easily.  While the plugs are out Id do a compression test.

What would the plugs look like if it was hydro-locked?  The plugs looked great, light grey even coating.

Dripping wet.


and since you left it that way a little rusty too, along with the rings, piston, etc, etc. That is if it didn't leak down into the oil-pan.

Yup what he said, Take the drain plug loose and look to see if water drips out.

What's the deal about the coil wire and shirts on fire??
