98 Dodge Ram question(s)

I think what is meant is to check for intake leaks. The magnum intakes have a habit of leaking through the valley area into the intake itself. {if you've got oil fouled plugs at the rear position, this is a sign of the leak] There is a kit sold that fixes this problem. There is a test also. I believe there is a ramchargers web site with the info. common problem.
