Re: can i turn over a packard motor with diesel instead of oil to clean out oil passages?

If it is that dirty, I suggest NOT running the engine with a solvent capable of cleaning oil passages to any great extent. The crud has to go somewhere and if a chunk is dislodged and redeposited where it blocks a smaller passage damage will occur. If you decide to go ahead then removing the pan and cleaning afterwards is a must. I'll spare you the details but a dirty V8 was given that cleaning method and what was a dirty but nicely functioning engine was quickly turned into an engine needing new bearings.
