Re: Needle bearing in Oil Pan
Needle Bearings Found in Oil Pan For
1998-2003 GM 4.8, 5.3, 5.7 & 6.0L VIN V, T, G, S & U Engines
The AERA Technical Committee supplies the following information regarding needle bearings in the oil pan for 1998-2002 GM 4.8, 5.3, 5.7 & 6.0L VIN V, T, G, S & U engines. Needle bearings have been observed in the discarded oil during routine engine oil changes.
The cause of this condition may be one or more rocker arms, which have experienced a bearing failure. To resolve this issue inspect all rocker arms for bearing cap failure and replace all 16 if one or more failed component is found.
If no abnormal condition is found with the rockers, check the vehicles service record for previous rocker arm repair. It is suggested if a previous repair was made, then the engine may not have been thoroughly cleaned of loose roller bearings.
Hope this helps,
