rburks, The job was done at a local shop, so I have no idea if the copper washers were replaced. They didn't charge me for washers, so I'm sure the old ones are in there. They said every o-ring was brittle and they suspected the shop that installed them 6 years ago did not use genuine Cummins brand o-rings. I really need my own shop area and to learn how to do this work myself. This event cost $1200.00 and 14 days without my truck. Thanks for the input everyone, you guys were spot on!

Update: Just got off the phone with the shop who said three of the injectors are bubbling fuel up around the edges thus adding fuel to the crank case. They said they have never seen three injectors fail like that at the same time. They should have the sticks pulled tomorrow and hopefully it's the o-rings and not an issue with the head. Now that you mention it rburks, I did see a ton of smoke when my son pulled out, but I figured he turned the programmer on. Only saw it once though. The injectors and o-rings are only six years old at the most, so I'm a little angry about that.

My 98.5 cummins has been in the shop for 8 days now and each day reveals a new problem. Took her in after a few hard starts where there seemed to be a loss of prime. The day before the shop appointment the oil pressure gauge suddenly dropped, then went immediately back to normal. I was a mile from home so I decided to limp her home, the oil pressure dropped to zero and then jumped back to normal as I pulled away from the intersection stop. Acceleration seemed to keep the oil pressure in the normal range. Anyway, I ger her to the shop who seems to start throwing parts at the problems. They replaced the oil pressure sensor and said the injector connector pencil o-rings were leaking causing loss of prime. After these repairs the problems continued and now they want to cut my oil filter apart and check for metal which I can understand. I just got off the phone with them and was told that fuel is entering the crank case and the oil level is way up on the dipstick. They are planning on pulling the valve cover tomorrow and checking to see if fuel is coming up around any injectors and draining away to the crank case. This still does not address my oil pressure issue unless the fuel thinned motor oil is causing the erratic readings. I trust the shop and they are very well though of in town. I would like to hear your thoughts and for any ideas you all might have.

Mine did the same thing a few weeks ago. Tried to pull away from the house and had no power brakes or steering. Shut it down, restarted and still no power. Inspected my belt and all pullies were spinning with no squeals. Tried to pull it forward a few feet (closer to the driveway and tools) when power brakes and steering returned. Shut her down and noticed my PS reservior had overflowed. Replaced the fluid and have had no issues since. Any thoughts?

I've received three banishment notices, but I'm still able to post, so I guess it's all good!

Things that make you go hummm? I live 60 miles from DieselAutoPower and am wondering if they would only bill me $45.00 to tune in the parking lot. I guess I'll call them tomorrow and find out. I need to set my tire height also as I'm 6 mph off according to the charts. Question to the board: Even in warm weather my grid heater cycles every few seconds. I have removed the IAT sensor to clean, but it was spotless as I have no exhaust brake. Should I replace the sensor, as I had to replace the MAP sensor a few years back? I get tired of that annoying click and light dimming when the heater cycles off and on.

If I can find some lexan what is the best took to cut it with?

My sump has only been on a few weeks, and yes I plan on going off road again. I'll have to be a little more careful now as I'd hate to rip it off and be stranded. I have not measured, but from just eyeing my truck, the sump and airdog are at the same height. I now have two things to worry about under there. I'd do it all over again to avoid low psi alerts when the fuel sloshed around.

I had the quarter tank issue at 3/8 tank and hated the alerts from my Edge every time I came to a stop. I had a Hellman sump installed a few weeks back and LOVE it. I have had no low fuel psi alerts since.

I couldn't agree more. I usually carry a longer one when traveling long distances.
