I just developed the dreaded lifter noise on my 07 5.3 Tahoe. It sounds like a tapping noise. It is on the driver side (most common) and apparently Chevrolet says this is a normal noise coming from the engine. Does anyone else have this and know how to get rid of it? It seems to happen after I have been driving for a few minutes and lasts about 5 minutes.

My 07 is doing the exact same thing. It last about 5 min and goes away. I used some engine restorer from the auto part store and it didn't occur again for a few weeks.

so its not a cold start noise yer talking about then
because mine starts ticking at random i could be driving around all day with no noise then on the freeway all the sudden it starts then all get off the freeway and get to the light and ill listen for it and its gone all the sudden
mine does it at random intervals maybe once a week for roughly 5 min give or take a few

This is the reason I'm getting rid of my Yukon, the noise is unbearable with 214k on ours. If I want to hear the clatter, I'd just drive my Duramax

Do these trucks have the oil filter screen below the pressure sensor that fliters the oil for the VVT hardware? I know GM built earlier engines with the hardware but not the software. I understand that a lot of these engines with higher miles have issues with the filters clogging and leading to valve train issues.

Yes they do. Just cleaned mine and replaced that damn oring at the oil catch pipe. Pressure is now stable

It was ok, but replaced it any way. Tahoe has 200,000 miles on it and oil is still clear

In front of the oil pressure sensor.

That's good to know. I've only got 75K on my Escalade but since it's a $7 part I picked on up and will probably change it out in the springtime while I'm doing other work.

Potato!
At that mileage I would try some Marvel Mystery Oil. It has some unique properties and can quiet noisy lifters. It can be used with synthetic, just add it for the last 1000 miles of the oil change. There's a good forum on their Web site.

I wouldn't change it yet. The mileage is too low. I would just add a cleaner before oil change, let it run for 5 min and drain oil, change, etc.

The screen that we are looking for is under the oil pressure sending switch at the back of the engine.. Here is a UTube clip on how to get at the filter screen. The oil pressure gauge will start acting screwy when the filter is clogging up. Key is to use good oil & filter and keep it clean. This is a 2 part view.

The only reason I'm contemplating it is I don't know the maintenance history for the first 70K miles. I only run synthetic in my vehicles but I don't know if the previous owners took care of the mechanical as well as they took care of the exterior and interior. I'm hoping so.
