Is Replacing the Cylinder Head Assembly Considered a Major Overhaul?
1 Answers
Replacing the cylinder head assembly is considered a major overhaul. Typically, the causes of cylinder head damage in automobiles include: alloy cylinder heads exposed to high temperatures; uneven tightening torque of cylinder head bolts; extensive burning of the cylinder gasket; and other external forces causing cylinder head damage. The problems caused by a damaged cylinder head are as follows: 1. While driving, you may often feel the engine lacks power and has difficulty accelerating. There may be air leakage sounds at the joint between the cylinder head and the cylinder block or in localized areas; 2. After starting the engine, one or two cylinders may not function, producing a 'bang, bang' sound. The radiator may continuously lose water, with bubbles appearing at the radiator filler neck, or oil droplets may be visible on the surface of the coolant; 3. When checking the engine oil by pulling out the dipstick, the oil may appear milky white. Water droplets may continuously flow out of the exhaust pipe; 4. The engine may overheat. When the cylinder gasket is severely damaged, not only does the engine power drop significantly, but sometimes it may even fail to start. Generally, when such faults occur, replacing the cylinder head is sufficient, and the engine oil should also be changed simultaneously.
