I found a 332 locally that I jumped on knowing it had a couple of issues. It has a large amount of blow by and runs rough. I have done a compression test and one is out of spec by a slight amount. The hour meter says it has 700 hours and works. The compression doesn't concern me but what does is the fact that the oil has fuel in it. I changed the oil to delvac 15 40 and just running it for 20 minutes or so the oil is diluted again. It blows diesel fuel out of the dipstick at idle. I took the injectors out and cleaned them and reassembled. I put fresh diesel fuel in after dumping the old along with a new filter. On mechanically injected Cummins and volkwagens they had a seal around the injection pump shaft behind the gear that ulsd fuel would dry out and cause fuel to leak into the oil....Is that the case with this as well? That would explain the fuel in the oil but not the running rough. Any suggestions?
