Re: Oil pressure gauge
If that is what you are refering to, then i think your ok.
When I start mine cold and go right away or wait just a little bit, it makes alot of noise but doesnt feel like it has much power, kinda like reduced engine power.
Same thing on my other car, chevy, probly like this on all gm if not all brands. I think its supposed to be like that as a safety until the engine warms up, thats what i think.
Re: Oil pressure gauge
The loud noise you hear on engine startup is what they call the "dirty hose" for the PCV system and the vacuum in the engine is causing the loud rushing noise.
GM did a bulletin on this for the 3.5L engine, that tells the dealers/techs it is a normal condition for this engine.
Honestly, not exactly sure why it happens only upon startup. However, I did find out it might happen at other times too. It happened to me coming down the Lasal mountain loop road into Moab for about two hours, and drove me crazy, and then it went away.
(ME TOO)
Re: Oil pressure gage
So yea, it will take few min. to warm up. Just the face on got me confused. Who reads car manuals, LOL!!!
