2010 5.3l Vvt And Low Oil Pressure @ Idle

[Jims Imperial Blue Crew]

I have a 2010 Crew Cab with the 5.3L, VVT and 25# oil pressure @ hot idle.

 

Is this normal for the VVT application?

 

My 2004 Silverado with the 5.3L(non VVT) had 40# @ 600 rpm hot idle.

 

Thanks for any input. Jim

10 psi for every 1000 rpms....thats all you need, from what i've read the GMT-900s run at a little less oil pressure then the 800s at idle...the guage is not dead on accurate, its more or less a dummy guage to tell you that you have pressure

Thanks for the input-looks like its normal

about the same here also...2010 chevy..5.3 and about 20 psi at idle 39 at highway speeds....I don't really think about that 10 psi per 1000 rpm...the gauge would look like a tach...I'm old school and anything under 50 at highway speeds gets My attention. I'll watch it while under warranty

50!? psi!?! jesus my oil pressure dosen't even hit that high when its in the negative outside with dino oil....

Mine runs 45psi at idle (i think the centre of the gauge is 40, mine's in kpa so 275kpa+ and 60 at highway speed 70psi if i'm in the 4500rpm range). I don't know what the gauge span is in the u.s. but mine is 0-550kpa. For the longest time chevy has said the oil press at idle should be 6+psi and 24+psi at hwy speed. That may have changed in later years when vvt came out but im not sure.

I'm a little bit relieved to hear others have about the same thing. I have a LY5 in a 2008 that has 25-30 lbs hot oil pressure assuming the gauge is a true linear scale. It runs over 40 down the road. My idle oil pressure has been one of the reasons I have been hesitant to get a tune for my truck. The AFM lifters are the other reason...

50 is not alot to ask for...You must be a youngster...My GTX and Superbee both start at 80 and run consistently at highway speeds of 68 psi.(warm) Idle on both is 45.

I don't know much about "new vehicles" but good oil pressure did mean good rings and compression.

there is no such thing as a 5.3L with VVT

 

you may have AFM, but you don't have VVT

The 2010 5.3L does have VVT.

[redvett]

NickV is correct, the first engines to get VVT will be the 2013 trucks. They will also be DI injected too.

Not sure what your source is about 2013, but they're wrong. The 4.8 and 5.3L are VVT engines NOW.

I got 2010 and its vvt... So 2013 is false
