I am almost finished refreshing my motor, and while I was setting the valve lash, I noticed that some of rockers shoot oil out while some of the others just kind of dribble out. They all seem to be oiling good, but why does the passenger side squirt oil and the other side doesn't?

 

not sure why but it's common and not a sign of a problem

 

I just set my valve lash last week and can confirm I saw the exact same behaviour.

Weird isn't it.

 

Lazy oil molecules?

 

yeah that's it
