Does anyone know how much oil actually makes it's way up to the top of the rocker boxes? The reason I am asking is I am finishing up my engine rebuild project and I am getting what sounds like excessive valve train noise. I pulled the rocker covers and started the engine to see what is going on. The valves are not hitting the piston, and I have adjusted and adjusted the pushrods, and the rockers are not hitting the covers. When looking through all of this, I noticed that I am not getting much oil to the top end. There is some, just not a lot as the MM would suggest, Is this right? Also any thoughts on the excessive noise? Thanks!! | ||

Unless the motor is at high revs for some time you'll see very little oil making its way up there. As far as the noise issue, you'd have to elaborate. | ||

It sounds like the normal HD noise, just louder. Normally I could hear some tapping in the top end and just figured it was the typical Harley valve noise of the tapet rockers and the valves moving. Now I have S&S roller rockers, Crane adjustable push rods, and Fueling lifters. The springs are Zippers 625 Pro-Street kit, w/titanium top collars and the valves are Stainless Steel valves. I have adjusted the push rods several times (loosened and tightened some) to see if that was the issue, but the noise is still there. From what I can see, nothing is hitting anywhere, it's just a louder clacking noise that should be. | ||

Roller rockers are usually noticeably noisier than stock. | ||

That's what I was kind of thinking, but I had someone else come over and they thought something was wrong too, so I guess this weekend I'm going to have it looked over by a HD mechanic friend of mine to see what he thinks. I'll keep ya posted as to the results. |
