I am not sure this is really a problem, but I have been going through my engine and replacing, fixing, and adjusting everything via the factory service manual. Sure enough the engine is running better and starting great, maybe too good however. I noticed that the engine fires up fast, but the oil pressure only creeps up. Before the engine turned over a time or two and seemed to build to oil pressure before starting.

It seems to me that even if the truck has sat for a little there should still be some oil around that there is no real problem for few second before the oil pressure builds up.

Opinions?

 

Don't worry about it.
