Camshaft Overhaul: Inspection

Check bearing surfaces and lobes for wear, galling, gouges and discoloration (overheating). Measure lift, bearing journal diameter and runout. Replace camshaft if not within specifications. See ENGINE SPECIFICATIONS tables at end of this article. If bearings are replaced, ensure oil holes are properly aligned. If installing new camshaft, add EP Lubricant (1051396) to engine oil.
