Iv'e had the Harland Sharp 1.7's in my 99 5.2 for about 15oo miles now and after the first 500 miles I've had a fairly loud whine noise from the upper part of the engine right where the rockers are. The whining starts around 2500 rpm and gets louder and higher pitched the faster the engine turns. I pulled the valve covers and inspected the rockers but they're wearing fine and retorqued them and that made no change in the noise. It almost seems like it's slowly getting worse but that might just be me but the engine is much louder than it was before I put the rollers on. Has anyone else had this problem? Also I run Mobil 1 5w30 and run about 50psi oil pressure engine cold and 30-35psi hot.

 

 

The guys over in the Ram section tend to have more experience with the engine mods like that since there are way more of them, so it might not hurt to ask your question over it the 2nd gen Ram section.
