6.2 oil pressure at idle

[Freddotron]

Hey all, first post here.

I've got a 2018 sierra that's been making a whining noise for a few days and tonight I just noticed my oil pressure at idle is somewhere around 10psi if my math is right. I dont think its typically that low.

I suspect the pump is going bad and I've got a check engine light on as well. Only 52000km on it.

It's going to the dealer tomorrow but do you think I have done any damage to the engine by driving like this?

Yes, you could have.  I wiuld use roadside or auto club to have it towed to the dealer.

 

Please keep us posted,

Change your oil.

What has the dealer told you about your issue?
