Default advice on ls1 problem

Hey need some advice regarding the following tsb?? my question is below..

Just saw this come out...
Thought you would all like to see this...

--------------------------------------------------------------------------------

1998-2002 Chevrolet Camaro, Corvette
1998-2002 Pontiac Firebird
2002 Cadillac Escalade, Escalade EXT
1999-2002 Chevrolet Silverado
2000-2002 Chevrolet Suburban, Tahoe

Condition
Some customers may comment or technicians may notice needle bearings being found during an engine oil change. The bearings may be found in either the drain pan used or on the magnetic oil pan drain plug.
Cause
One or more rocker arms may have experienced a bearing failure.
Correction
Inspect all of the rocker arms for bearing retainer cap failure. If one or more defective rocker arms are found, replace all 16 rocker arms. Refer to the Engine Mechanical sub-section in the appropriate Service Manual.
If no condition with the rocker arms is found, refer to the service history for previous rocker arm repair. If previous rocker arm repair was made, then the engine may not have been thoroughly cleaned of loose roller bearings. If no previous rocker arm repair was made, then look for another condition.
Remove the oil pan and clean out any additional bearings found within the oil pan. Refer to the Engine Mechanical sub-section in the appropriate Service Manual.
Install the oil pan. Refer to the Engine Mechanical sub-section in the appropriate Service Manual.

Question : I have ordered slp rockerarms , ls6 springs, titanium retainers and valve savers , but my question is I am going to clean the oil pan of the needle bearings, but do you think it is likely that some bearings can remain that could cause problems, would you keep this car?

Thanx!
p.s. Car only has 30, 000 miles. and my car is just out of warranty, and although they admit above it is a defect they wont work with me on this

This has been out for a while on this board. Too bad the dealership wont fix it for you. If you remove the oil pan completely and clean it out as well as replace the parts. I dont think you will have any other trouble. :nono:

I agree with vetterdstr, as long as you're removing the pan, and cleaning all needle bearings out, you should be OK, just make sure to look really close to make sure you get them all, also look around the top of the cylinder head to make sure none have lodged in the valvesprings, etc.

You never actually said you have bearings in your oil pan. Do you?
