New cam chest - funny noise

New cam chest - funny noise
I just rebuilt the cam chest on the 05 SE Electraglide due to front lifters going bad, (roller faces were pitted) . I used a screamin eagle cam plate/oil pump and adjustable pushrods along with S & S lifters and 551 cams. I replaced the inside bearings with the new torringtons that came with the cams. I aligned the oil pump by rotating the rear wheel and slowly tightening down the bolts. For the first 150 miles it sounded fine,but as it came to idle after it was warm I heard a faint sound that almost sounded like how the lifter was acting before it failed causing the replacement. The sound only seems to be there at idle and sometimes not even then. Oil pressure at idle is 30+ and going down the road it is at the 3/4 mark. As soon as it cools down I will look at the lifters but if is not them I guess I will take the cam cover off and have a look. When the front lifters initially went bad it was suggested that they might be oil starved, but everything looked clean on the inside. I'm not sure what I should be looking for. I'm guessing the failure rate of new lifters is almost nil. I did have the rocker covers off and the rockers out when I was originally searching for the problem. Could it be something up there? It really doesn't sound like it is coming from that high but I want to make sure I'm not overlooking anything obvious.

While they might have had enough oil to lubricate them they might not be getting enough oil to pump them up. I might be way off but its something to think about. I am not sure what port you would tap to flush to see if you have something like a small piece of gasket or silicon blocking it. Good luck.

Are your S&S lifters HLT2 lifters? With the travel limiters in them? If so, these are inherently noisey. I have them, and they sound like solids. That's not what you described, with an intermittent noise, but if those lifters have the travel limiters in them I don't think you're ever going to get them to be silent. At least I haven't been able to.

Sounds like the problem.
