How to adjust the valves of the Aowei 11-liter 460?

First, locate the top dead center of the first cylinder and adjust the intake valves of cylinders 1, 2, and 4 to 0.3MM. Then, rotate the crankshaft one full turn to the top dead center of the sixth cylinder and adjust the intake valves of cylinders 3, 5, and 6 to 0.30MM. Next, starting from the exhaust valve of the sixth cylinder, adjust one exhaust valve every 120° in the order of 6, 2, 4, 1, 5, 3 to 3.00MM.
I remember adjusting the valve clearance on the Aowei 11-liter 460 engine is a technical task, based on my decades of experience as a machinist. First, ensure the engine is completely cooled, having been stopped for at least half a day. Then remove the valve cover and locate the adjustment bolt for each valve. Use a feeler gauge to measure the clearance—intake valves are generally between 0.25 to 0.30 mm, and exhaust valves between 0.30 to 0.35 mm, but always refer to the engine model manual for specifics. When adjusting, gently turn the bolt to ensure the clearance is correct after tightening, being careful not to overtighten or leave it too loose, as this could lead to abnormal valve wear or engine seizure. After adjustment, reinstall the cover and start the engine to check for any unusual noises. I recommend checking every six months, especially for vehicles used for long-distance travel, to prevent carbon buildup or oil deposits from affecting performance. Neglecting these small details can lead to major failures like power loss or cylinder seizure, which would be a costly mistake. In short, thoroughly reading the manual before starting is key.
