i have a 36 that I can not get the oil stop from leaking from the eng. the seal looks good but willnot stop leaking I have heard that you can convert it to a rope seal. does any one know what has to be done to do this?

Are you sure it is not the pan cork seal or the rear cam cover ? Do you have the drain pipe in place ? If yes is it scr*w*d in too far ? If it is scr*w*d in too far it acts as a dam and causes a leak . Another cause is a rear main that is a little loose - especially the back half . No simple cure all answer on this and the stock setup works fine if all is in good order .

I have taken the pan off and the cork is fine at the rear of the pan and I checked the rear main and it had 1*5th ( did this with the engine still in the car),I also made pressure pot and preasureized the oil system in through the oil sending unit with the pan of and every thing looked fine oil did not look like is was coming out where it should not have been. I also put a fitting into the drain hole on the clutch housing and piped it into a gal can. I did fint that the oil was coming out of the chutch area. when I had the pan off, I took the rear main cap off and the lower labyrinth seal looks fine. Roger Oliver

How much oil pressure are you running ? Did this issue start out of the blue or has it always done this . Do you have the pipe in the threaded hole in the rear main cap ? If yes does it reach down to the oil ?

yes it reaches into the and I found a new pipe from little dearbourn and they are shipping it to me and the hole is not pluged. this all started when I got the car from a shop in Mn they got it from a estate, so there is no tracking it down. I got the car home and decided to change the oil not knowing the history of the car. it did not look as if was leaking any oil then, I changed the oil and I put 4 qts in and it did not show on the dip stick so I put in 2 more thinking it was a 6 qt. drove it a half mile and oil was all over. drained 2 qts out, and it will not stop throwing the oil. the dip stik was me.

Capacity is 5 quarts of oil . What weight oil are you running ? The pipe should only be turned in about 5 turns or so . If it is scr*w*d in too far it WILL cause a leak . Look closely at the rear cap and pipe and you will see why . What does 1-5 clearance mean ? How did you measure this ? The clearance on the rear half of the rear main [ behind the groove ] is real important with a labyrinth seal . Your oil pressure is not the culprit .

i have 1.5 thousands measured with plastigage. i think i might have found the trouble, who ever put this eng together never put the pot metal seal in the bottom. but when i went to put one in it would not fit. i think some one inter change the main bearing cap with a different one. i am in the process of trying to find a different bearing cap.
