Are there any problems with my Cummins L10?
Are there any problems with my Cummins L10? Cummins L10 problems.... Have a 93 L10 - 300 (non celect) upon startup it smokes and runs rough, once warm it smooths out and no smoke exept on load. Strangly when i use the block heater it does not smoke for the first 5 mins of start up but then starts to run rough again and smoke until warm....??? could the thermostat cause this? Is the Cummins M11 the same as the L10? Re: Cummins L10 owners, good and bad about the motor? While the L10 is a mechanical engine with 330hp...
