Spartan tuned with oil leak - Advice needed
Need some advice here, 2008 job 1 6.4l with ~16K mi. Spartan tuned since 5K mi with only the 250 tune run. The truck has not been driven hard and was primarily tuned to stop the oil dilution problem due to the regen. Small amount of oil leaking from the rear of the motor. I have read that it could be a number of things including the bed plate. Before I return this truck to stock and take it in for warranty is there anything special I should do to enhance my chances that they will not even suspect that a tuner was used on the truck and potentially deny the warranty claim? Sadly the DOC looks new.....
Anybody know any good dealerships in MA or NH?
Thanks in advance!
