I was wondering where you people are finding parts for the 4d55 I just aquiered 2 dodge d50's neither were running when I got them. The injection pump was out on one of them. I took the pump off tonight and noticed the ballance shaft belt was off. The ballance shaft is locked down,pulled the cover off of the ballance shaft and found traces of water. The engine in the other one also has some internal problems its pretty much locked down has a little movement but not much, no holes in the block so I guess thats a plus. My local carquest store can get a rebuid kit for it but nothing in the was a ballance or a crank shaft. Any help would be greatly appreciated.
