on my 89 f150 4x4 the rear main seal is leakin oil and tranny fluid. dosent seem to be a lot. just drops every now and then. but i was told that its really bad for a manual tranny cause oil will get on clutch and cause to slip. how long will it take to do all this and is there anything i can do besides replace it

 

anybody?

 

Its hard to say. Soon as the clutch gets oil soaked. If I remember correctly from your post in the engine forum you said you use your truck to pull some kind of trailer. That would be a concern. A load on a possibly oil soak clutch isnt good. This is why people who have manuals should replace the rear main every time they replace the clutch. Dont forget the Slave cylinder either. You have to R& R the tranny to fix that and its a cheap part. The rear main is easy to fix once the trannys out.

 

If the rear main seal is not gushing it will simply leak behind the flywheel. That oil will be flung onto the bellhousing. It will then drip down the sides. If it is a lot of oil it will drip straight down from the top onto the flywheel. If the input shaft seal on your tranny is leaking it will simply drip down the bellhousing and out the drain hole. The oil leaking from the transmission is not something to ignore. If the seal is leaking the bearing is loosing lubrication.
