Hey guys
Just a question, what kind of oil pressure should the 4JB1 have at cold idle? Hot idle?
4th gear 50kms and full boost?

I have just started using genuine filters and notice a higher oil pressure 7-8 on the gauge until its hot, then sits halfway.

Whats normal? As i dont remeber it sitting so high.

Cheers in advance

most diesels have high oil pressure while the engine is cold.
Normal for every isuzu I have seen
