Good afternoon,
we have a A990 tribute with a stroked 426 Hemi where the oil preassure is behaving very suspicious. At idle it does hardly 8-10psi, at 2500rm it starts at 40psi but drops to 20psi after 1min of running approximately. The external oil pump has been replaced & checked, removing the oil pan indicates that the rorating assembly is brand new with just a few miles on it. I also tried 2 different gauges, both show the same fluctuation. Next stop would be to pull the engine and take it apart...but before going down that rout i thought i ask if that rings a bell for anyone who has had a similar issue in the past? Thanks for help in advance
