Is your 2.2L engine losing oil pressure or making unusual noises? This might be your oil pump crying for help! This replacement oil pump from OELINE Autoparts is designed specifically for 1996-2003 Chevrolet Cavaliers, Pontiac Berettas, and GMC Sonomas with the 2.2L engine. The part number is OEOP05778, and it cross-references with OEM numbers OP328 and M248, so you know it's the right fit. It's brand new, comes with a 1-year warranty, and is a direct replacement - no modifications needed. Replacing an oil pump is a bit more involved than some repairs (you'll need to drop the oil pan), but if you're mechanically inclined, it's totally doable. This is a critical component - without proper oil pressure, you could seriously damage your engine. So if you're seeing low pressure on your gauge, hearing rattling from the bottom end, or just doing a complete engine rebuild, this is the pump you need. Much cheaper than engine replacement! Install it with a fresh oil change and filter, and your 2.2L should run smoothly for years to come. Don't ignore oil pressure issues - fix them before they fix your wallet!
