If the engine runs poorly, has a misfire, and/or loss of compression after camshaft installation, it may be caused by the hydraulic valve lifters over extending while the cam was out. If the lifters are extended, they will hold the valves open and cause a loss of compression. Our technicians recommend running the engine for 15 minutes, or let it sit overnight to allow the lifters to readjust to the proper position.
