Washers. No there wasn't no washers on the original part. Metal to metal There's a YouTube video showed how mine is leaking. Oil comes from around it as they drive it. But there wasn't no washers on factory part that I took of.

Between the bolt and the pipe joint there should be washers at both sides. Seems they were not installed previously or were they stuck to the pipe you removed?

OEM uses aluminium washers to prevent leakages.
Copper washers can be used as substitute.

Well I put aluminum washers above an below. Sat it was before I started. It already had one on top. Must not have seen the one on bottom, anyway. The leak is still there. New line new washers an it leaks just like it did before I started. I wiped off all around where it's bolted down. It's clean. It doesn't leak ideal ing I put on stands. Took tires of. Block it. Put in gear. Doesn't start leaking unless I raised rpm while in gear about 20 to 40 mph. Then it started leaking in that area I wiped oil of. Over an over it still does it like seeping from there. Has any one else have this problem. There's a you tube same thing going on. Thank you for your help

Check for cracks along the threads. Overtightening by previous owner could have damaged it. Try using some packing tape around the washers to see if it helps.

Leaking only at high speed occurs when the pressure is high.
