As I knew from reading the old papers that came with our coach our oil ban drain bolt hole has a helicoil in it.
The edge of the hole is enlarged enough to cause a small drip around the copper crush ring.
If I were home I would have the shop remove the pan and hand it to me and my tap removal place could install a timesert into the aluminum pan.
Logistics in the future would seem to work out to source a pan somewhere and then repair this one.
Almost 2 CB's to replace at the Cummins dealer.
Anyone have any feedback about this? Pan part number? Low profile aluminum
Thanks
Bob
Check those companies that make those drain valves,they may have an oversized one.
Hey Bob -
Our 2002 U320 M11 had a cast aluminum oil pan and did not have a helicoil in it until the oil was changed at a Cummins shop in Mesa, AZ. It was detected by my Mobile oil change guy about 6 months later in Houston. Had a local mechanic, Bo Reese, pull the pan, put in a Cummins SS insert kit and replaced the pan on the block. Total cost was about $800.00. After numerous calls and emails with/to Cummins, they did reimburse the cost of this repair. It was determined that the Cummins Tech that changed the oil damaged the threads and put the helicoil in to tighten the threads so it did not drip oil. He neglected to tell any body but "fessed" up after my complaint. The pan is cast aluminum and the plug is SS, It can be over-torqued which can damage the oil pan threads - hense the helicoil. I forget what the torque ft/lbs - in/lbs spec is but is quite low.
Yours is probably different, but is a known problem to Cummins as they do manufacturer a "Kit" with a SS insert and plug. The Pan threaded hole is bored out, re tapped then the insert is held in place with Lock Tite.
When Bo finished it was better than new.
This happened a few years ago and was documented on this forum.
If I recall a new pan was about $1500.00 .
Good luck. :)
Thanks for the info on the "kit"
