Sloooooow work week. Decided to strip down the front of the truck now instead of doing everything when the new turbos come in. Did a leak down test on all cylinders number 3 and 4 were the worse of the bunch if I recall it was....

Now this motor has years of passes with George and around 80-100 with me. I can not complain one bit on our findings. Cylinder walls looked good, pistons and rings seem fine just need a good cleaning. No leakage was detected from the rings, most all of the leakage came out of the exhaust ports. Head does need a valve job and since it is off it is getting ported and polished by HotRodDiesels. I was hoping to have more to do this week with the truck but we can not do much more until the head is done except for tapping the block for studs and little BS.
Doing Studs, Bigger Injectors, 64/480, head job, PP exhaust/bowls, custom turbo piping and a serious under hood clean up. Also got a billet output shaft but I think that is going to wait until later because of all the parts it involves to get the damn thing in. Funds or there lack of now has put that aside for a while. Here are a few pics so far.
Anything funny you experienced guys see on the piston tops? I saw no contact dings on the tops everything is just dirty, no telling when the last time this head was off.
