Good Morning

Well, my severe oil leak is GONE !

Put on 400 miles this past weekend and not one drop of oil under the coach,
after the last trip the entire underside from the trans back was wet with oil.

Turned out to be the trans vent, I think I would be the only person that could
install the vent fitting, add a hose and run the hose to the underside of the
coach and create by accident a PERFECT venturi system. All I did as put a
prescription pill bottle over the end of the hose, drilled a 1/2" hole in the
cap, stuck in the hose, done. Literally not one drop of oil in the bottle
either. I did check all fluid levels before leaving and did add 1 qt of trans
oil so all fluids were at correct levels.

Thanks for all of the help guys and I apologize if I sent any innocent
bystanders on fire drills like Jim K.

Ray, when I was at Miguel's, a couple of years back, he told me that they had had the same problem a few times. Don't run the hose too far back or it might just do what your's did. Never a drop from my little short line, so far.
Glad you got it taken care of.

Ray,

That's incredible!

When you get the opportunity could you take a picture of where the vent hose
is located and how it is attached.

Regards,
Rob M.

I really have a hard time believing that a vacuum was created with just the end of the hose hanging loose. I still think it was just a matter of the transmission being overfilled. As I asked in a previous reply, did you add oil just before the trip in which you had the leak?
I put a vent hose on mine and ran it to the right side. It never dripped a bit until I added fluid last year. It then blew a fair amount of oil down the underside of the coach. I added a catch cup as you did and it has not dripped since. But I believe that it just got rid of as much oil as needed before I added the cup. But I am leaving the cup in case I overfill again.

Hard for me to believe too Rick, I started both trips with the exact same amount
of fluid in the trans, 1st trip I lost 2 qts, bottom of the entire coach was
full of oil, 2nd trip with the bottle on, not one drop lost and not a drop in
the bottle.

I think my coach is possessed !

Thanks Dan.

I do have a couple of minor oil leaks I need to fix, got a new oil filter/cooler
adapter gasket from Jim K, I need new valve cover gaskets too, that should take
care of the oil leaks.

Are there any special valve cover gaskets recommended for the 403 ???

I have a hard time believing that too. I think I have had this problem and I am wondering if that hose could siphon oil from the tranny. What is on the inside of that vent? Is it a tube going down into the area of the pan maybe? If it were a tube then all it would need is a little overfill and the right conditions (?) to get the siphoning started.

the bottle could stop the low pressure pulling on the opening of the hose that is going 60 miles an hour
and hanging slightly backwards that could cause a wing foil like sucking on the tube. It would show up
as the oil would have to be towards the back of the vehicle starting and not going farther forward than
the hose position hanging from the transmission. A- being the hose position, B- being the area behind it
the way the wind would blow and C- the area forward of the hose position to the front bumper.
If area C is clean toward the front bumper then this would prove that the hose is doing it to a high degree.
If area B is clean after the bottle towards the rear bumper then this builds
the evidence that the hose is doing it. I have a small amount when parked that seems to come out at times
over night or as i am parked.
i notice some stain on the ground under it from solar eclipse ratios of the sun by the earth
commonly called day and night. Minor amounts but there.

the butler may have done it as well.

I think i will put a bottle on mine now that you have started this. This saves the evidence.

Manny always stated put a little plastic bottle on it.

I am interested in where to attach it and the right size and design. thank you

faithfully,

Mickey

The way my luck goes, if I spent $5 million trying to design a siphon that did
this I would never get it to work, but by shear chance I may have cut the hose
to perfect length, routed it and hung the tip down perfect...... I need to run
out and buy some lottery tickets !

Still hard to believe that sticking a Rx bottle on the end changed it.....makes
no sense to me !

I think you should do some more testing. Next trip, remove the bottle and see what happens. I would try it on mine but seeing that I am retired, I do not have as much spare time as you. You will find this out when you retire.

the volume of the trans case changes temperature, even when it sets in the sun, i suppose this

pressure change as well, can also help the possible event. the electrons of the masses increase radius.

Wow - can I testify to that!!!!! Lets see, GMC, railroad museum, welding class, machine tool class, pool, 20 acres, 6 vehicles other than the GMC, 2 Harleys, firewood, Her Royal Highness Queen Chloe the Goffin's Cockatoo, organizing the shop and barn, dealing with the in-laws for LL, and I'm sure I missed something. At this rate I'm gonna have to go back to work so I can get some down time.

Here's a thought. Is the dip stick sealed or vented? (I can't remember which.) If vented it might not take as much vacuum as you would think to get air flow through the trans and to carry trans fluid along with the air flow.

Armand,

It vents the chain case.

See MM X-7525 Page 7-6 Transmission Figure 6 - Case Oil passages - Rear

IIRC when asked what would cause oil to vent Manny noted - overfilling the trans and/or a sloppy chain as both would sling oil
around the chain case ID.

Regards,
Rob M.

I'll check that Steve....really weird, like I said, I think my coach is
possessed.

Did you read my email on the boat ??

Yep, and I replied twice but my ISP does not like your name.

I think you should start a thread on your boat problem and how Dick Paterson, unbeknown to him, had the answer to your problem. GMC's could also have this problem.

Steve,

According to Manny the OEM dipstick is vented; there can be a problem with the custom remote ones that are under the hood next to
the oil dipstick if they're not vented.

The remote one on Double Trouble wasn't vented so I decided to drill a hole in it so it would be.

Dumb ass that I am I decided that since it is a well known fact that water gets past the hoods like crazy I would drill a hole in
the BOTTOM of the tube so that water couldn't get in it. It worked great until the first time I needed to add fluid. Sure the water
couldn't get in the hole cause it was on the bottom but trans fluid damn sure could get out when I added it! DOUH!

I wound up wrapping some duck tape around the tube to stop the problem.

Regards,
Rob M.

Here's a thought. Is the dip stick sealed or vented? (I can't remember which.) If vented it might not take as much vacuum as you
would think to get air flow through the trans and to carry trans fluid along with the air flow.

Rob, that figure (MM X-7525 Page 7-6 Transmission Figure 6 - Case Oil passages - Rear) shows two arrows for some reason and no real detail. Do you know if that is just an opening or is it somehow connected lower in the transmission? I am real curious about this because my former transmission kept losing oil - sometimes really fast - and it finally killed it. No leaks will be tolerated this time.

Armand,

The dotted line between the two arrows represents a drilled passageway.

I found another picture that may clarify it a bit: Page 7-60 Figure 88 - Pump Cover Plate Screws

Look to the right of the word "PIN" - it appears that there is a small "flap" that covers the end of the tube.

Regards,
Rob M.
