A few 4.6 issues (noises and oil psi)
i have an after market oil psi gauge and when i go above 3 grand my stock dummy one drops down in the red but my aftermarket one is between 60 and 95 depending on hot or cold motor, why does this do this?
also ever since i broke my stock harmonic balancer and tensioner pullie from the belt slipping off (after installing a used working altenator) ive had an annoying and a lil bit nasty rattle sound at the high rpms, but when that stuff broke i installed underdrive pullies and a brand new tensioner.
please give some suggestions i need to fix these before it starts to get cold.
