1922 Model 35 rear main seal advice

[Guest JosR]

Wanted to say thanks to all the good folks and their great advice which helped me totally rebuild by tired 4 cylinder. I took the kids for a ride yesterday and boy what a difference with good compression! The only area I will have to address is a nasty oil leak out the rear of the engine. I thought I did a good job by packing some old rope seal material into the block grooveunder the crank and using the felt seal provided by Olsens gaskets, but it drips about every second. I have posted a pic for reference. Any advice? Thanks, Jos
