It did me the 1st few times it did that but I am confident it is more of a sender problem than a pressure problem.
I recently had a Melling high volume oil pump installed just in case and it still has the same problem.
I have no ticking at all and it runs fine.
If it really had 0psi there is no way it would still be running.
And it really runs good, I have saw 180mph (on a private airfield runway)

Okey dokey...
I'm not the only who have put thicker oil, -currently use Castrol 10-40 in the summer, and have no more lifter noise.
I'm not going to argue about technical data about mobil, I couldn't care less other than the fact a slightly higher set of numbers helped.
It would be nice if the original poster reports back in the future on whether it helped.
Peace out,

I plan to change the oil soon. I want to let my tuner hear this first to verify my "gut feel" that it is lifter. I am driving on a long trip at the end of next month. I will change the oil before I leave. I ran a can of fuel injector cleaner last night in the remaining hopes that it is a dirty injector.
I'm not totally bummed it is a lifter. I eventually will change heads and cam but the current economy has delayed it a tad. I will definitely report back on my findings.
Thanks all for your input.

If you have to add a higher viscosity oil to rid yourself of a noise within the engine, you are masking the problem.

Another thing to keep in mind is everyone's sensitivity to issues like this (especially sounds) is different. In fact, when I first noticed this sound, I asked a friend if his C5 did the same thing. He swore up and down it didn't. Then I met him for lunch one day. As we were leaving, I made it a point to wait for him to crank up first, and when he did sure enough .. clatter clatter. So ....

^ I typo'd 10-30
I still have the empty Castrol 10-40 oil bottles in my garage. I can snap pictures after work to prove it.
It just sucks that dingleberry has to bash people who are helping. His post offered nothing but snide critcism.

Normally I'd agree, but this is a very common problem. Just Google it. The LSX and Holden boards are full of people talking about the startup tapping. If a lifter bleeds down with hot, water thin oil but doesn't with a slightly thicker grade is that a problem or a design flaw or a loose machining tolerance? *shrugs*

On a side note, I have a pinging that some may think is nothing, but my ear's are very sensitive and I can hear it...

Without trying to sound cocky, I have excellent hearing. I was tested by my last employer, and I managed to test past the maximum sensitivity of their equipment. With that being said, it's a very obvious clatter to me. It's much easier to hear in the cabin than outside though. But if the radio is on at all, it drowns it out.

I got rid of my pinging (and knock sensor code) with a Seafoam treatment and adding a PCV catch can to ward off future buildup.

Yep, pinging under hard acceleration... I'm in the first stages of trouble shooting, have read probably 30 threads here on it...did the Techron in gas tank, cleaned maf, and now I have seafoam in the tank (which is actually helping)...will do seafoam in the intake as soon as I need my next oil change, and will do plugs after too...not getting any knock sensor codes, and remember seeing the silicone on the back sensor when we did the oil pressure sending unit the other month...(which means new sensor from previous owner)...

I have a similar sound in my '04 Chev truck. 5.3L LS based motor but an iron block vs. al in my C5.
Can't really hear it in my C5, mostly due to the louder exhaust. Always use 5w-30 Mobile1.
The truck, at cold start up, sounds like piston slap. Goes away within 15 to 20 secs. Plenty of oil pressure. 30,000mi. 10w-30 oil. Do these motors have aluminum pistons?
