Camshaft Service Video

The camshaft controls when your engine’s valves open and close. This service video explains how its lobes keep valve timing synchronized with piston movement so the engine can breathe, burn fuel, and release exhaust gases efficiently.

As the camshaft rotates, each lobe presses on a lifter, rocker arm, or follower. This motion opens a valve at the correct moment, then lets it close before combustion continues.

Common signs of camshaft wear include a ticking noise from the top of the engine, rough idle, reduced power, misfires, and poor fuel economy. These symptoms can also come from other valve-train or timing problems, so testing should come before replacement.

Worn cam lobes reduce valve lift and disturb engine timing. A technician may inspect oil pressure, scan for fault codes, check valve movement, and compare camshaft and crankshaft signals before confirming the cause.

Alvin’s summer heat can keep oil temperatures high during long drives. If the oil is low, old, or the wrong viscosity, its protective film may weaken and allow faster wear between the camshaft lobes and valve-train parts.

Domestic SUVs, Asian commuter cars, and European vehicles traveling on Highway 35, Highway 6, or toward I-45 often face long highway runs mixed with school-zone stops. These driving patterns make smooth valve operation and proper lubrication important.

Genesis Auto Repair can diagnose ticking, rough running, or lost power before recommending internal engine work. Learn more about engine diagnostics and repair when these symptoms appear.

Drivers from Pearland, Manvel, Friendswood, and across Brazoria County can visit a mechanic in Alvin for help. Call (281) 968-7411 today if the noise or performance loss is getting worse.
