My chevrolet silverado from 2006 has the engine rebuilt.

Customer Question

my chevrolet silverado from 2006 has the engine rebuilt. during the rebuilt, the shop advise me to eliminate the oil cooler, since the damage to my engine could be linked with that. i approve it. i do not have any issue with temparature now but i notice that, just from start, the engine move (one small bar) in the temperature gauge in less one minute. it used to take longer, at least 3 minutes. it is normal? could come some problems in the future? this engine is the 6.0 chevy.
what are the normal oil pressure readings with engine warm at operational temperature but in idle?

Hi, my name is Jay

The normal oil pressure below 1000 rpm with warm engine is only 6 psig. At 2000 it should be about 18 and at 4000 rpm it should about 24 psig. The rate the engine warms to operating temperature should take about 5 minutes and what you describe is okay as long as it does not overheat.
