Visual defect detection of valve guide bushings using the example of a set of so-called "bronze" crap valve guide bushings from Stinger sport, which they cobbled together for me from 3 sets, including the factory one. Valve guide bushings are a rather important part of the cylinder head. Bushings require increased manufacturing precision to eliminate skewing and misalignment of the valve relative to the seat. When repairing, and especially when tuning the cylinder head, it is necessary to pay special attention to the quality of the valve guide bushings. Defect detection must be carried out in order not to insert all sorts of crap into the engine, which is now being riveted and sold by all sorts of Stinger Sports, and not to lose money, time and nerves. The long-term, reliable and trouble-free operation of the timing belt of your engine directly depends on the quality of the valve guide bushings.
