390 -rear main seal replacement
By James - 02/23/2003 8:04:37 AM; IP 217.44.83.202
Hi
I've got an oil leak at the back of my 390 (1968 GT). I did a search on this site, and found previous posts. so this is what I spent a whole day doing, upside-down under the car:
1) Dropped the oil, removed the pan
2) Loosened all of the caps, removed the rear one, removed all of old seal.
3) made sure grove/lip side is facing front of engine, poked new seal into block, around the crank. left 3/8" sticking out.
4) with corresponding gap, put in main rear cap, with loads of RTV black, and bolted it all up.
5) Put everything back, filled with oil, fired her up, AND IT STILL LEAKS !

Any Ideas what I did wrong? I remember a little rubber shaving off the inside of the seal as it went into the block - but that was from the inside!
I did have a bit of a problem with one of the side seals also.
I did my best to clean all surfaces with water and detergent.

any help is appreciated - thanks

James
