Advanced Racing Engines High-Vac Cam Seal Set for Toyota 2JZ Engine Intended for use in 2JZ Engines equipped with Vacuum Pumps or Dry Sump Oil Systems. Designed to hold crankcase vacuum where OEM Seals fail. These are the same style seals we use in our competition level engine builds, which operate at or above 20in/hg of crankcase vacuum under load/power. Constructed with an aluminum shell and double Teflon seal lips, our seals will keep oil inside your engine, while keeping outside air and contaminants out even under the most unforgiving conditions. Some applications will not maintain crankcase vacuum under high boost and/or with methanol fuel simply due to too much pressure getting past the piston rings. The good news is, our seals don't let anything out either! They are stronger than OEM, and deal with crankcase pressure just as well as they hold up to crankcase vacuum! It should be noted that these seals will not magically yield a large amount of crankcase vacuum in engines with blow-by issues. Kit includes (2) Cam Seals. For best results, pair this product with our Advanced Racing Engines High Vac Front Main Seal, and Rear Main Seal.
