rear main seal

[blkstangman88]

is there a certain way to install the rear main seal? i installed one, make it flush with the steel like the shops told me and a week after installing it i have an oil leak again!!!! i cleans the whole and rubbed oil on the seal b4 insertion aswell, am i missing somthing?

you might just have one of those stangs that the rear main will always leak. i've replaced mine 3 times and finally just said the hell with it. it's a very common problem with the 5.0.

is there a sealant i can shove in there? im asking this cuz its now leaking faster then it was b4 i replaced it.

no, sealant won't work there because of the movement of the input shaft.
i've always installed mine using a flat body hammer gently tapping it in all the way around. mine have always leaked on both of my mustangs, i've just kind of accepted it. mine's not too bad though, i usually only have a drop or two on the bottom of the bellhousing.

you probably need a crank sleeve.....your local parts store should have one

Mine leaks as well. As BlueDevil95 said it is a very common problem with the 5.0.

i just notcied my old engine had a small leak (302) and just installed a new rear main seal on the 347 but haven't tested it yet. Your susposedly susposed to use a special insterion tool so the seal is spaced the proper distance from the block otherwise the seal will wear and leak thats the general problem, no one uses the right tool and it leaks, but I somewhat do the same thing cause im not forking over 120 bucks for a ford rear main seal insterion tool just to install a seal one time.
