Oil Pressure Gauge Maxed Out

[EPIC CAJUN]

OK, had a dealer oil change done last Thursday as part of my 2 year service crap they offer. Well over the weekend, I noticed several times while driving the Oil Pressure gauge will max out for a couple seconds then return to around 40% where it usually stays. This is occurring well after the engine is at operating temp.I know the gauge will move along with the rpm when cold. Is this something normal for this engine? (hahaha yea right) Could my gauge be bad? Im waiting for parts to come in later this week for my drivers seat fix so the truck is going back in a couple days. I called the dealer and they said to watch it for a day or so and if it keeps doing it to bring it in.

 

Has this happened to anyone else?

Condition/Concern

The customer may comment that the oil pressure gauge jumps from approximately 40 lb. to 60 lb. three times within the first few minutes of driving as well when the engine revs past 3700 RPM.

 

Recommendation/Instructions

The 4.3L (L83), 5.3L (L86), 6.2L (LV3) engines are equipped with a two stage oil pump.

The oil pressure gauge jumping three times is caused by a test routine the engine goes through during the first few minutes of driving to insure that both stages are operable.

The oil pressure gauge going to 60 lb. over 3700 RPM, is the calibrated engine speed the oil pump goes into the high pressure stage.

No repairs should be attempted.

This is normal operation for these engines.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Thanks man. Sounds like that is whats going on. Even though I wouldn't call 30 minutes later within the first few minutes and my rpm's were at 1500. But this still makes me feel better.

Completely normal.
