ACL cam bearings for 1970–1985 Mazda engines restore camshaft support and bearing clearance for the listed 1.6–2.0L applications. Brought as replacement bearings, they address journal wear and help re-establish correct oil film at the camshaft to improve valvetrain stability during rebuilds or servicing of older Mazda powerplants.
