lifter ticking on cold start My '01 tahoe 5.3 has a loud tick on cold start up. It goes away after about 20-30 seconds. It has around 100K on the engine, and use mobile 10-30. Is this going to hurt the engine, should i do some kind of flush or what????

I think I have the same thing on my '96 Blazer. I am chalking it up as a "lazy" lifter. It goes away so I am not too worried about it. Just going to replace a qt with 20-50 next oil change.
