It did not get a complete rebuild. No pistons or liners. Extent of head work, don't recall. Knowing how meticulous dad was on details...I'd be surprised if the timing and valve adjustment was off. Will have to dig through his notes as he even kept a record of all the bearing clearances during assembly.

The "nailing" is random harsher diesel knock "cracking". If it was consistent I could narrow it down by cracking injectors. Replaced some leaking crush washers on the LP, pulled the relief spring on the pump and found it compressed to 21 MM stretched to 27/8 and now showing 13 psi at the filter head.

Have read enough threads about people finding compressed DV springs to consider it a legit concern. Wouldn't be surprised if there is internal pump damage as it was low on oil and had poor maintenance when we got it.

Need to flip the cab so I can easily access the side of the pump and check linkage and try to figure out why it won't shut off.

Raw fuel, know that smell. Trying to start the ole IH3500A in -20*F without a block heater.


Free....not likely.

This is not my first, or only Diesel, just my only old MB.
More familiar with setting timing and DVs on my P7100.
