Oil pan fun

Yahoo Message Number: 105044
Well I discovered an oil leak evidenced by oil on the garage floor. This great coach has a steel skid plate and so I removed that to find the leak. Cleaned everything up spic and span and found that the leak is in the composite material oil pan. I also found that there had been a repair to this pan sometime in the past and it was this repair that is leaking.. Since I bought the coach new I can confidently say that this repair was not done on my watch. I talked to Cummins and they said the skid plate was installed by Country Coach and so I have to believe that it was CC that damaged and repaired the oil pan. Cummins, as you might expect, NOW disavows the composite pan in favor of a steel one. Cummins SW in Albuquerque sent me a long list of all the parts needed for substitution to steel. It is long and expensive because it entails much more than just the pan.
Here is my plan: tomorrow I will dump the oil and further clean the bottom of the pan; then I will repair the pan in order to complete a trip planned to begin next week; of course this means a complete oil change; upon return from the anticipated trip I will order all the necessary parts and have a local diesel truck shop make the switch to steel; this of course means another oil change. Because this coach is for sale I wanted any prospective buyers to know that no expense will be spared to complete the necessary switch to steel and anything else that may be required. If anyone has "been there-done that" all input is welcome.

been there too

a patch on the composite pan will not hold, the cracks are soaked with oil. i think it cost me around $1000 for cummins to replace it. .

Yes and no! The CC repair has lasted for 12 years. However, they may have repaired it prior to introduction of any oil although that is kinda remote. They obviously installed the skid plate and mounts for some reason though. My repair is intended as a one trip deal only situation. Upon return home a steel pan will be professionally installed. I estimated today's cost at about $1600 since the parts alone now are just over $1000.

You are very lucky my pan only lasted 5 years. The fixture that comes out the back of the pan that contains the temp sensor worked itself loose from the pan eventually cracking the pan causing a leak. There is a long list of things I had to have done to make the new metal pan interface with the exsisting CC design. So I feel your pain. If you were going to Oregon this year I would say let OMC or Cummins NW in Cohburg do the work. I had to have RM Cummins do the work.

PS. Make sure who ever does the work warrants the work, because replacing the pan gasket is not duck soup.

Had the same problem with an 07 allure with the Cummins engine. The composite pan they use is garbage and a major issue here, however, I found that replacing the pan bolts/seals stopped the leak.

Sorry you guys had this issue. I have a 2007 ISL and it has a steel pan. Never knew that Cummins ever used a composite oil pan. Was this on early year models? Mine is the 425 clean diesel with DPF so wonder if that is the difference.

There are some great resources for used oil pans (steel) at the semi truck recycle yards, a lot cheaper than going to Cummins I bought mine for 195 bucks at G & O truck parts in Jackson ca. Gasket was not cheap but got it all done for less than 450

I likewise have a 2007 Siskiyou summit 42 foot and it does have the composite pan which I have replace the bolts and Seals to stop the oil leaking. Any further problems I'll put on a steel pan. It is an early production 400 HP non smog engine. I bought my coach new, & I believe it was the last coach Country Coach Sold before they went bankrupt. They did stiff me on the warranty however, I purchased an extended warranty since that time and I have a warranty now through 2018. best thing I ever did!!!

My 1998 Intrigue's 6CTA 8.3L 325 had to have the oil pan replaced, the previous owner had it done at Cummins in Saint Paul MN in 2013. It was replaced with another composite pan and (I assume) all new bolts & seals & gaskets. It is still in good shape and not cracked or leaking; at least not yet. I'm going to change my oil next month when I get it out for spring so I can give it a closer inspection then.

I can understand the benefit of a composite material oil pan after having to replace the steel oil pan on my Ford Powerstroke pickup (which entails pulling the engine completely out of the vehicle) when it rusted completely through from our Minnesota winters. But since my coach is no longer driven in the winter, if I need to replace the oil pan again it would be with a steel one if possible.

I did call them and they didn't seem to know very much indicated they didn't have very many Cummins ISL parts come through. I will check with Cummins and country coach

The oil pickup tube and associated parts are different on the steel pan, and as you might expect, they are not cheap from Cummins. Don't know if anybody else would have those.

I'm wondering if they're all interchangeable with the ISL 400

Hi Group. I have been having a problem with oil residue (spots) on my tow vehicle. The locale Cat dealer recommends that a aftermarket mist filtration system. This converts an open crankcase ventilation system to a closed crankcase system. Has anyone heared of this or done this install?

Sorry about the highjack of this message, but I can't post a new message.

Bo, I had the ISL in a previous coach converted to a closed system as you describe. Cummins did the work in hopes of solving the same issue you are having with your engine. In my case the problem was not solved. There are many other possible sources of light oiling of the towed vehicle and the rear of the coach. I once had a plugged vent on a rear axle causing oil to be forced past the drive axle hub seal. The problem in the case of my ISL was ongoing leaks at the oil pan seal. That problem was eventually solved by the replacement of the pan isolators with a new design. All this took place in 2004 or 2005.

Good luck with your problem.

Thank you George. I have found a leaking seal on the power streeing/Coolant pump. I'll have to adress that issue first.
