I find this. The flange bolts were tight, but I could easily rotate the manifold by hand. Rear manifold seal leaking oil. I did the bypass not long ago, so this is probably residual - but still - that's quite a bit isn't it?

Something else going on here that I'm missing?

 

Pretty nasty. How many miles do you have on it?

 

Just shy of 27k.

 

When I finished the manifold swap I installed the updated HD Stage 2 tune, then went for a quick 15 mile ride to get it hot, then check for any leaks etc.

Sure runs better.

 

My manifold looked the same. This happened before you did the breather bypass. I'm sure your new manifold will stay clean.

 

Makes you wonder why so many are anti-bypass doesn't it?

 

I guess they believe this is acceptable.
