Let's look at some pistons. One of these pistons got a little warm. Can you tell which one? Hmmm...

Head had aluminum frosting sprinkled with ring bits. This will need reconditioning.

Cylinder 5 and 6 are really hard to get to. Instrument panel has to come out to get to the dog house cover. Make sure you label every little connector.

Liners come out with a liner-jack. Make sure you install the new ones carefully. Check and recheck everything.

Heating the pistons is necessary to remove and install the wrist pins. Nothing warms the heart like a cookie sheet of pistons going into the oven.
It's best to do this while the OCD wife is out of the house for a few hours.

Install the rings while watching the game.

Here's a fuel/fuel tank cleaner I made. I'm to cheap to drain and dispose of 40+ gal. of diesel and the tank needed rinsed out. I remove the drain plug, drain the fuel into a container. The pump sucks the fuel out of container, filters it, then sprays it out of the hose while I direct the stream of clean fuel at the interior walls of the tank. The fuel drains back into the catch container and the whole process repeats until the fuel and tank are clean.

Nice cast work on that left piston BTW

very impressive on everything. I suspect you have done this at least once before....

Nice fuel tank flusher. Did you make it? Also very cool.

Thanks for sharing

Thanks for the complements. This is the first time rebuilding a NHC250, however, I have over 250 text messages from a good friend who has done this type of motor hundreds of times (no exaggeration ) and he helped me with the valves and injectors with his magical touch.
I made the tank flusher from a Harbor Freight pump, a whole house water filter, and misc. pieces. Note however, that the filter is good for particulates down to 15 micron, but NOT water. Just sayin.
