Just wondering if tightening the valve springs up a little bit will give it a little more RPM?
404 diesel motor
 
To late I adjusted them! An it runs better already ! All the valves seem to shut right now then before. Can the oil pump be one tooth or two off will that cause it to push a little oil out the exaust?
 
Ummmm no..... Oil being pushed out the exhaust is either worn piston rings, improper injection timing, injectors with low crack pressure, and likely either a missing thermostat or a non operating thermostat.
 
Sounds like you don't need to be working on your own tractor. No offense.
Probably bad injector slobbering out the exhaust.
