Noticed a slow oil leak coming from oil pan on ISL 400

Yahoo Message Number: 67705
I noticed a small puddle under the coach on my ISL 400, after 2000 miles dip stick just down 1/4 in. So i crawled under and noticed the rear of the pan there is two or three fittings and a hose connected. I could move the fittings and hose everything including the large bolt flush with the. The slow leak appears to be coming from the area between the pan and large bolt. Seems to me I read these pans are fibreglass, I put a wrench on the fittings all were tight except the large one next to the pan. So not wanting to cause any problems, I am wondering if anyone knows how these bolts are seated to the pan? I was wondering if this large bolt was stripped? Not sure how it connects to the oil pan.

Jerry, Hi, yes your pan is Fiberglass. Its hard for me to explain but its a combination of carefully tightning the large nutt, then hold the large nut and tighten the inner bolt.
Inside this combination is an "O" Ring its possible during Oil Changes that the "O" Ring got abused. The Cummins "O" Ring Pt. #3939919. Of course to replace this "O" Ring you would have to drain your Oil completely.
I would try carefully tighten this combination, turn on engine get the oil warm, then let set overnight and check for leak. My 2003 Allure with same pan does not have the "hoses" you mention, just the drain "nut/plug" at rear of pan.

Thanks, Mike 03 Allure 1st Ave. #30898

I had a leak at that fitting this summer. Here is what the shop wrote: "drained the oil, removed fitting and hose, tightened fittings, reinstalled fittings and hose" One hour of labor at $75 and $6 to top off the oil.

Where do you get work done for $75 an hour?

Although your question was likely rhetorical, I will answer it anyway.
I had the work done at Jacksons Garage in Celina Ohio. I was down that way from Michigan having some work done at a couple of RV shops when I noticed the leak. It is a 10 bay or so garage with various affiliations. It appears they work on principally grain hauling trucks as this is a major corn and soybean farming region and most all the grains are trucked up to Toledo for great lakes/ocean shipping. And they probably work on some farm equipment too. They got me in right away and clearly didn't rip me off as an out of towner. It is nice to know that there are professional service shops sometimes a bit off the beaten path that are providing service at more reasonable rates.
And I can't say enough for the shops where I had the RV work done. One was From Trees to These in Decatur Indiana who installed my thin screen TV's including all the cabinet mods, put in adjustable and roll out shelves throughout and put in some sliding trays and shelves in the basement. The other shop was Cruising America RV in Celina Ohio. They are two guys who used to work for American Coach. They installed an autoformer and and auto gen start that would also operate the AC's (mine was for low battery only) and a bunch of other minor stuff. And both of these shops were very reasonable price wise too.
I will be back down there this Spring for more work in final preparation for full timing (washer/dryer, satellite dish, etc). It is good that we have shops here in the midwest that can work on a country coach and do so at good labor rates.

Thanks for asking.
