What is a good number at idle and a good number while running down the road for an engine with 175,000 miles? I just installed a mechanical gauge and I am thinking that the numbers are a bit weird. When I fire my truck up cold I get 57 psi at idle, and rolling it reads 60-65. After it is at operating temp I see about 25-30 at idle and 46psi while driving. These numbers seem high to me and I was wondering what you guys though.
Thanks,
Russell
