Hey IDI guys, new update:
I Did the compression test today. The numbers in order from 1-8 in psi are;
Seems fine to me. The cylinders that have >415 compression may have leaky valve stem seals making them have higher compression. It seems like it will run just fine though, and they are all healthy. I’ve been told they need a minimum of 275psi to fire.
I borrowed batteries and cables, removed the starter and put it back in. Worked great. I am still going to build a couple sets of cables soon.
We cranked it for long enough that anywhere that would leak oil did, and it looks like I need to reseal the IP housing. The main seals appear to have been replaced and are fine, as are the valve covers and oil pan.
It is looking like I will do the following and then install the motor. In addition to some small tinkering, I will pull the valve covers, torque the heads, new thermostat, radiator hoses, water pump, glow plugs, and oil cooler seals, reseal the IP housing, install new motor mounts, delete the ats turbo pedestal and valve cover tube (not sure exactly how…see below) and re-torque all the essential and non-essential bolts. Also need to swap the transmission adapter and flex plate.
Did I miss anything major? It ran without knocking, and the compression seems healthy, so mechanically the motor seems fine. I will reseal the leaking spots, and replace the common failure points, but we’re there any I missed? Not gonna do intake seals or head gaskets, main seals or valve stems. Like I mentioned the main seals and oil pan, etc have been done.
Anything else major I should do?
Any advice on deleting the ats turbo parts? The shaft is worn out so I can’t run it with the turbo on. What is the best way to seal up the intake manifold and valley pan once I remove the pedestal? The air filter housing clears the pedestal, but there isn’t enough room for a block off plate, though it may still be a possibility. I think I’ll rout the vent tube into the exhaust.
Let me know any ideas and advice you may have. You guys have been a great help to me!
