My 5.9 Magnum build has 650 miles on it. It runs great. I used the valve cover gaskets that were original to the engine and I'm getting a little oil leaking so I bought new gaskets.
While I have the valve covers off should I reset lifter preload? The engine runs great and I'm not getting any drive train noise. I did notice at TDC I'm able to barely spin #1 pushrods. Isn't it better to have a less preload than a little too much?
Thanks in advance!
