Success, I hope.
Yesterday, using the suggestions provided by those on this forum along with process of elimination steps, and a second set of eyes from some folks and our winter park,I believe the elusive leak has been solved.
1. All fittings, filters connected to the hydraulic oil cannister in the engine compartment were checked and found to be tight.
2. The big o cummins motor was started and run for about 40 minutes @ 1300rpm and reached about 170-75 degrees.
3. No joy as I noticed about 8-10 "reddish" colored oily feeling on the ground in the same general area as before. Crap!!!!!
4. I had siphoned almost 14oz out of the obvious overfill from the hydraulic fluid cannister before starting the engine so was certain it wasn't that. The fluid also appeared "brownish" in color anyway.
5. ATF trans fluid? Hope not and it wasn't.
(Before starting step #6, we waited an hour or so for the engine to cool)
6. When we dug behind a jumble of wires around the bottom of the hydraulic fluid cannister, a black rubber tube was in the jumble and was an overflow tube coming from the antifreeze tank. It was moist on the bottom opening and just above where a lot of "reddish" liquid has dropped.
7. I then carefully loosened the radiator cap and after the gurgling stopped, I looked in the fill tube and the "reddish" colored antifreeze with the same feel as the drips on the ground, was no more than 1 inch from the top of the fill tube. Maybe a little overfilled. Let it cool over night.
8. Checked this am and the level has dropped maybe an inch. After siphoning off about 3/4 gal, the level seems to be where it should be.
9. Thanks everyone for ur help. It makes owning an rv more tolerable when Murphy's Law pops up.
