[Tony]

Good Afternoon,

soes anyone have access to GM's tsb's? This is a very current one
that won't be on alldata for a while. I have the info listed below:

============

02-06-01-038; Engine Knock or Lifter Noise (Replace O-Ring); 2001-03
Cars and LD Trucks with 4.8L, 5.3L, 5.7L or 6.0L V8 Engine (VINs V, T,
Z, G, S, N, U -- RPOs LR4, LM7, L59, LS1, LS6, LQ9, LQ4)

============

I have been following the piston slap issue with the 6.0L vortec
engines. I was wondering what the latest fix is...

Thanks

Tony

I saw this too on the GM teklink site, it will be a long time for details to
be available, check with your dealer they are required to supply you with
this info. Or maybe discuss it with them to see if it applies to a problem
in your engine, they probably just received this also.

This one isn't related to piston slap:

"Some customers may comment on an engine tick noise. The distinguishing
characteristic of this condition is that it likely will have been present
since new, and is typically noticed within the first 161-322 km (100-200
mi). The noise may often be diagnosed as a collapsed lifter. Additionally,
the noise may be present at cold start and appear to diminish and then
return as the engine warms to operating temperature. This noise is different
from other noises that may begin to occur at 3219-4828 km (2000-3000 mi).

Cause:

The O-ring seal between the oil pump screen and the oil pump may be cut,
causing aeration of the oil.

Correction:

Inspect the O-ring seal and replace as necessary. Use the applicable part
number listed below. Refer to the Engine Mechanical sub-section of the
appropriate Service Manual."
