Fits 1997-2013 LS-based engines (up to 2018 on L96 engines).
One of the most common causes of low oil pressure on high mileage or aged LS engines is the oil pickup tube O-ring at the oil pump inlet. These O-rings harden with age and heat, eventually allowing the oil pump to pull air in past the seal. This kit from Melling includes both styles/thicknesses of O-rings used on the LS engines as well as instructions to identify which seal you need to use, eliminating the need to identify or guess which O-ring you have before ordering.
