730D fuel leak

Brian Jasper co. Ia · Jul 15, 2017

I have the really bad kind of fuel leak, it's leaking into the crankcase. I also noticed when I pulled it to start it was hydro locked and what it spit out of the muffler smelled like fuel. Makes me think I have a nozzle tip that may be leaking while sitting. I take it it's time to go through the pump and nozzles. Any recommendations on who to see in the central Iowa area?

The two cylinder pumps I see in for repair it's common for the internal gaskets to leak on the pumps, and also the injector inlet fittings. Although I'm not in Iowa, I do have the Woodring & Wise two cylinder test stand to verify the pumps and injectors are balanced well and don't leak while on the test bench. Have a 70 set on it right now..
