My oil pressure keeps dropping on the gauge, i know im still getting pressure and oil as i looked in the valve covers. When i start her up the gaude says im around 40 but when i start driving it drops to 30, 20, 0, then the 'check gauges' light comes on. i replaced the oil pressure sender thinking that went, but it is still doing it. i have a new oil pump too, any ideas?

 

Would you describe this as fairly good pressure when cold and gets progressively worse the hotter the engine gets?<O</O

How many miles on this engine?<O</O

the engine itself is fairly new i replaced it last winter approx 20000 miles on it. and the hotter it gets the worse the problem gets.

 

install a mechanical gauge and then you will know. After all you have done, it may be the instrument cluster but a mechanical gauge will assure you none the less.

 

Yep,

Put a good mechanical gauge on it. If you're still showing that pressure dropping way off when it's hot, you've got lower end bearing trouble.
