Hello C. Group
After 2600 miles on rebuilt 413,
# 7
Cylinder has a clacking lifter , then after
Warm up, it continues to tack -tack.
Should I be concerned to pull valve cover and replace it?
Hopefully it won't come apart during the Ashville run.
Engine is lubricated with Amsoil 10/30.
25 PSI on hot idle.
Pull it or drive it.
Your floor.
Thanks
Dave D.
