Planning a major engine repair like a head gasket job on your Toyota Corolla, Matrix, Pontiac Vibe, or Celica? This AUTOSITY full cylinder engine gasket set has everything you need in one box. It's a complete kit designed specifically for the 1.8L engine found in models from 2000 to 2008. It replaces OEM numbers like 7-4232 and TO3030325. The gaskets are made from high-quality, non-asbestos materials – think graphite or MLS for the head gasket and viton for the valve stem seals – so they'll seal tight and last. The kit even includes the necessary bolts and RTV adhesive. It's a direct fit, so no drilling or modifying is needed, which saves a ton of time. This is a serious job, so we highly recommend professional installation if you're not an experienced DIYer. But if you are, this kit is a reliable and affordable way to get your engine sealed up right. It even comes with a crazy 50-year warranty against defects!
