318 stroker oil leak :(

Cam plug in backwards, let me get a pic of mine and you'll see the problem. The first is of my new 360 and the second is from a 1970 318 that is factory original. It's my small parts motor. I made that mistake on a 70 340 years ago. I had the same problem you have and pulled the trans to fix it. It sucks laying on your back trying to get the old one out and a new one in. I think the cam bangs against the cup and lets it leak oil.
