howdy all
i just bought a 1986 jd 310c backhoe , i have found oil in the coolant and when i dropped the oil out of the pan i filled just about a full 5 gallon bucket with oil and mistry fluid. the motor holds 9 qt of oil.
i drove the backhoe home it was about 5 miles away motor didnt smoke and didnt run hot . i found this problem by checking the machine over.
this is what i have done so far
the oil smelled a little like fuel ,i pulled the lift pump ( transfer pump) off with the lines hooded up and pumped it and fuel did come out from the cam rod of the pump. i replaced it
i also removed the motor oil cooler located under the oil filter and applied pressure ( 100 pounds ) didnt really see any bubbles in the soapy water.
my question is
could have the head gasket at one time started leaking and they didnt flush the system out. i need opions here lol would you run the tractor and keep check every couple hours to see if oil level or coolant color changes or go right into the head gasket replacement .
motor runs great ,easy starting cold, no smoke of any color
machine has 8000 hours on it
all opions are welcome thanks
