Break Down Description: Oil Leak - Major. I bought the motor home in Mar 2017. We I got it home I first noticed an oil on the ground under the engine. I had it evaluated at Colton Truck Terminal in Colton CA. They told me it was coming from the back of the HEUI Pump.Advice was to monitor it but since it wasn't that large a leak no repair at this time.I put about 2k miles on it. On Sep 1 We had just returned from a trip from San Diego to Lake Tahoe. The REV was parked in front of my house and we were preparing to leave on an extended 6 week trip. I started it and re-positioned it a few feet, got out and had a full on oil spill under the engine. It looked like a quart or so leaked out in about 5 minutes. It was streaming out not dripping.
Symptoms: Major visible oil streaming out of the bottom of the engine compartment.
Effect: Disabled out of fear of major engine damage
Cause: Broken bolt that fastened fuel transfer pump to the back of the HEUI pump
Outcome:The HEUI Pump and Fuel Transfer Pump are sold only as an assembly. 2k for parts 1.2k labor.
Note: I feel very fortunate this happen in front of my house and not on the road.
Postscript: On Sep 16 we left on our originally planned trip. On arrival in Las Vegas, our first stop, I noticed oil was being sprayed on our tow car along with oil drops on the ground. Needless to say I was more than a little disappointed. I rigged up a catch for the "slobber" tube thinking it was blow by. Drove 240 miles to Ely, NV and there was still some oil drops and some spray on the car. Cleaned up the spay and drove another 120 miles to Wendover UT. Significant spray on the toad and more significant drops on the ground. In checking the engine oil level found no detectable loss of oil. I contacted the main CAT dealer in Salt Lake City UT. They didn't work on the over the road engines anymore but referred me to Larry H Miller Super Ford in Salt Lake City.
These guys were GREAT! Tyler the service writer and Ken their in house CAT expert.This car dealership is an authorized service center for CAT, Allison, and Spartan. In spite of a 4 week work back log they told me to come right over and they would have a mechanic take a look at it and at least tell be where the leak was. Ken really knew the C9. In short order he found the leak.It was a leaking o-Ring in the air compressor oil supply line. He removed it, installed new o-rings and I was on my way. Drove 40 miles to Park City UT and not a drop on the Toad or ground. The oil leak odyssey for us is finally over and we are proceeding on our trip with a peace of mind we haven't really had yet with this motor home. I just can't thank those guys at Larry H Miller Super Ford enough!
