Re: Leaking 351 clevo at rear
If its coming from inside the bell housing area then its likely to be a leaking rear main seal. You need to try and find out accurately where the oil is coming from if you can. Sometimes it can run from an area on the engine to somewhere else and trick you as to its origin.
Clean the oil up with some engine degreaser then do a small drive and check where the source is if you can.
A rear main seal has a bit of work involved on a Cleveland.
