What happens if I disassemble my dash cam?
Disassembling the camera will almost always void the warranty but you may have no choice as return shipping (especially China for cheap products) may cost too much money.

How many camshafts are in a double overhead camshaft engine?
A double overhead camshaft (DOHC or “twin-cam”) engine has two camshafts per bank of the cylinder head, one for the intake valves and the other for the exhaust valves. Therefore there are two camshafts for a straight engine and a total of four camshafts for a V engine or a flat engine.
What makes a dual overhead camshaft a DOHC?
Generally, engines with dual overhead camshafts (DOHC) are higher performance engines, they produce more power, and can run at higher speeds. The camshafts have the job of opening the valves that let air into and exhaust out of the engine. The camshaft uses rotating lobes, called cams, that push against the valves to open them.

Are there any cam timing errors in a DOHC engine?
If there are errors in cam timing on DOHC engines, it’s rare that both the intake and exhaust cam will have the same exact error in the same exact direction (i.e. both intake and exhaust cam are advanced two degrees or retarded four degrees). More often, cam timing errors are different between the intake and exhaust cams.
