Outer Limits 4x4 Board

That happened about a year ago but since then i didnt checked it out again. But today i had some problems with the gears (very hard to change gears) so i took a picture so you can see. I believe is not the trasfer oil but the engine oil because the limit of the Engine oil got lower. Did any one of you have the same problem?

Not good at thinking upside down.....

Its looks like its comming from the rear main seal ( engine ). Not a quick fix - so unless its loosing lots of engine oil - ignore it.

Although there does seem to be some other oil on the belhousing, so check that the distributor oil seal isn't leaking and running down the back
of the engine onto the belhousing. This tye of leak is not that uncommon.

Agreed - Looks to be rear main seal, which when it leaks can soak the clutch in oil, making it slip. Check above the gearbox though, around the back of the tappet cover and distributor as Mighty Mouse said it may be coming from above. Ream main seal is not that hard to do, but required removal of gearbox.

Layto....

Ok my mistake forget the previous picture (the other oil stuff is something that i created to clean up the gearbox) here is the real problem (is not from inside the bell house but as you sayed from the engine)



Anyway as you sayed is not a big problem but i am also lucky because i will change the clutch and with in the price of changing the clutch they also change the oil shields with new ones. But any other thoughts could be useful. Thanks anyway.

I've got the same sort of thing with my Rocky, but its the input shaft seal on the gearbox...

Wait til the clutch dies from the oil contamination, and fix it then

Is dead thats why i am lucky that it will be fixed in a minute. I will put more pictures when the job is done.

I very similar problem on my F60 Scat, it turned out to be the rocker cover seal was leaking at the rear. The DL engine is quite close to the firewall was difficult to see, but I replace the rocker cover seal, the problem stopped.
It is always a good idea to keep a eye on both the engine and gearbox oil levels.

If its coming round from teh top of the bellhousing, its not the rear main or gearbox input seal. Think about it, unless that oil is made by Bentzook himself it cant alter the laws of gravity, and will flow down. Follow the oil trail up, most lilkey to rocker cover or distributor seal.

If i find a way to fit my head inside there or a camera i will tell you.

Things like that aren't always visible from the top in the engine bay. For a long time I thought it was the crank seal as the gearbox was not losing oil. When I replaced the rocker cover seal, it stopped. Only when I removed the gearbox for rebuild, I found the trail from the rocker cover to the bottom of the bell housing.

Don't be quick to discount anything as things aren't always as it seems as I found from experience. Gravity will not find the most direct route but the easiest route.

I can be wrong as much as anyone.

Thats why you wash the motor down, then take it for a good run then go over it with a torch and a mirror if you have to.

Layto....

if you look carefully the photo is from the underneath ( unless of course the front diff is on top of the engine..... )

So the oil appears to be comming from the bottom of the belhousing -
which makes everyone comments very relevant. Could possibly be
any of the places suggested.

The oil however appears a little discolored and a bit thinner than gearbox
oil so theres a greater chance of it being engine oil - but time will tell.

i have just changed my r/m/s on my rocky and had oil dripping from the same spot after submerging my car for an hour it started leaking the next day. if your clutch is rooted or worn you mays well change that while the box is out. for a new clutch, rear main fitted about $800 the clutch was $300, rms $30, the rest was labour

Have a another look at the photo, I noticed a oil patch on the sump around the same area. The sump gasket might just leaking from the rear right near the lowest point of the bell housing. They might be connected, is there any oil marks running down the flywheel cover plate? But the where is patch running down the starter motor side coming from?

The oil does look too thin to be gearbox oil (75-90w vs 15-30w?).
