I did a quick walk around the trucks (4) in our terminal. Everyone has a little oil around that breather. Is it possible that the breather was plugged with gunk for so long and finally got freed up so the oil could come out? The world may never know.

 

truck went into the shop tues. shop mgr said leak was not normal. most likely a bearing going out. a lot of drivers told me not to worry, that it was normal. if thats the case then the rear has been broke for 10 years & now it's normal. lol. cause no leak for 10 years until now. anyway the shop folks are hometown folks & they will be honest about what the problem is. will post when I get fixed

 

got back out from shop.. a couple of bearing were pitted & really needed replaced. I asked if that would cause oil to come out of vent? he said yes. he said everything else, gears e.t.c. looked good. have not drove but 10 miles from shop, well see next week when I go on road if prob solved.. thanx for replies

 

I can't imagine pitted bearings causing the oil to come out but I haven't seen everything. Seeing how it was ten years old there was a 99% chance they would find some wear on something. I'm curious to see if it fixes the oil thing.

 

I'm skeptical too.

 

they told me the only thing to make oil come out of the vent was heat. if the oil in the rear got too hot it would come out the vent & the bearing going out will cause the oil to get hotter than it normally would. it cost $1045 to get the work done. I hope to have a load mon, the 13th. if I do I will surely know when I get back.

 

If you have a leak in your rear you didn't use enough toilet paper.

 

finally got to drive. drove 380 miles. oil still coming out from vent. I guess I'll just drive it like it is. I cant afford another misdiagnosis. maybe it will not be a problem. the bearings may very well needed replacing. though it did not solve the oil vent prob. the rear has never had anything done to it ever except oil changes since 1995. so maybe I am lucky. thanks for all the input.

 

I'm sure getting it re-bearinged was money well spent even if it didn't stop the seepage. One less thing you'll have to worry about now.
Just keep the oil level with the plug and keep an eye on it. If you don't lose a lot I would say it's just needing to vent. At least it's venting there and not blowing seals.

 

Thanks for the optimistic view Larry. I cannot complain. after 11 years & over 1.2 mil I have gone farther than most o/o's. the trans went 1.1 mil from the factory before I had to do anything to it, & then all I did was have clutch put in & it is still going. got over a mil before doing anything to any part of truck, except the usual wear & tear items. the engine has yet to be rebuilt. so after paying $15,000 cash for it & having it all this time. with no more than I spent on it, I consider myself 1 of the lucky ones. have a great wknd folks...
