Another good weekend, I finished building and loading the pistons in the liners. Installed the cam, counter shaft, oil pump, end plate, timing gears, oil pump drive gear and front cover.:) Finally starting to look like an engine again, next weekend is loading the liners.
Cross Head piston assembly:

Nice progress. When you get it done you'll have a basically brand new engine. Gaining plenty of knowledge at the same time.

Found an old 6.4 video, so I uploaded a cabin noise comparison for fun.:) Detroit was 60.5 at idle and around 75-78 at 2000 rpm.

Happy times, got the head assembled and torqued down. Injectors, lines and rack are in as well. I found a bent rack control arm that I missed before. I've straightened it now and just testing it to make sure it's free. Not far off getting it finished up.:)

Looks so much more complicated as compared to a B Cummins. Can't wait to see a first start vid!

True, it's really not anymore complicated, just different.:) I'm dying to hear it run as well.

Had a good weekend on the Detroit. Installed the rear housing, front, rear crank seals and sleeves, shimmed the governor down from 3200 to 3000 rpm. Flushed the oil cooler, oil pick up tube, washed and installed the oil pan. Next weekend it's the blower, oil cooler, Jake heads, tune up and engine start.:)

It's alive.:) Finally got it tuned up and quick test run up to check for leaks. Very happy with the results, super responsive now that I have the new cam and pistons in it. As well, I worked on the governor and fixed a few issues I noticed. Very happy indeed.:)

Another fun weekend on my 4-53T. Changed the out my K27 bypass actuator for another unit that now opens at 15 psi instead of 30. This will hopefully lower egt's and help light the k31. Mounted up the turbo's and made a new fuel shutoff system using a second gen solenoid. Just a couple of items left and the engine goes back in the frame.:)

Happy times, she's back in the chassis.:) Repaired a high spot on the cross member and then put the engine back in. I'll soon be converting diesel fuel into noise.:)

Got the truck turned around and most of the hardware re-attached. Did a quick start to test for leaks and no leaks found.:) Started working on putting the Turbo breather back on the valve cover. The N style I made had no baffles so a lot of oil would puke out the breather. It shouldn't puke anymore now that it's a new engine, but better safe than sorry.:) I should have the cover finished and get the rig rolling by the weekend.:)

Start and leak check.:)

Bringing back up your AN fittings on your AC system. Do they seem to be working out ok? Are you running any ORB fittings in your system? Making some parts up for my expedition ac system and just making sure you are having good luck. I had to make a custom line adapter that bolts to the compressor so I could get the lines pointed in the right direction and I cut ORB fittings for the lines to adapt to, from there ill go to AN stuff.
