all, need some tech advice, i have a 2006 F350 crew cab, last December, I had a leak between the engine and tranny , the dealer replaced a gasket and said fixed....ok well Feb, 09 another leak in the same place and they replaced the seal again, this time they added dye and to verify that it was leaking....i thought pretty smart......and of course yes it leaked agin this time worse.....so now they tell me they need to pull the engine and replace the crankshaft and a sleeve....they couldnt explain where the sleeve went and what its purpose is........so i m totally confused....

Probably it's the bed plate seal that is leaking. All to common. Mine leaks too but not that badly yet. Still have 11 months to get it fixed.
