1997 Ford F150 4.2L V6 - HYDROLOCK
Hello.
I bought a 1997 Ford F150 4.2L V6 from the company that I work for. I got the truck for $200.00 before I found out that it was hydrolocked from a gasket leak. The truck has 144,000 miles, but other wise it is in great shape.
I am preparing to rebuild the engine. It is winter and I do not have anything else to do, so what the heck!!
My plan is to tear it apart and see what is messed up. It starts (after draining the coolant out of the cylinders) and runs. It is a little ruff and knocks pretty loud, but does not shake too bad. I am hoping that it will just be a couple of bent rods as the worst. a couple of new parts, new bearings all around and of course new gaskets for the whole engine.
If anybody out there has done this before and has any advise, it will be greatly appreciated.

No matter what it cost you for the new engine, you only paid $200. Now you'll have a truck with a new engine. It should be good for another 100,000 miles. What could go wrong? Considering it's a '97 w/ 144,000 miles; you'll just have to be ready to fix whatever else breaks on it next. Radiator, fan, electrical, emissions control, exhaust, transmission, brake system, and whatever else. That, and do all the deferred maintenance. What could go wrong?

Well guess what???? We got the motor out of the truck and tore down. All that we found was a bent piston connecting rod and some piston damage. The machine shop
said that all was good with the crank and block. We do not even have any bent pushrods. I am thinking that we got very lucky!! So I am looking at around $700.00 for a total rebuild cost. That includes all new gaskets and bearings throughout the motor.

Nice, just remember to change the timing cover gasket, that was the major cause of H-lock on these motors. Get the gaskets right from Ford, not the Felpro ones. In the future if you notice the coolant level in the overflow bottle going down but there is no visible leak, you are looking at a possible h-lock again.

Had that problem
My 4.2L hydrolocked at 140K. #2 piston pushrod broke in two. Rebuilt myself, but this seems to be a common problem with 4.2L up until 2000. Looking to motor swap with a 4.6L or 5.4L. I have a 5 speed manual, and I believe they will bolt to a 4.6, but i'm not sure. Any help?
