Is a Bent Valve Considered a Major Overhaul?

[SanPaislee]

Bent valves are not considered a major overhaul, as explained below. Explanation of Bent Valves: During normal engine operation, the pistons do not come into contact with the valves. However, when a valve fails to close as it should, the piston may strike the valve, bending it. This is known as a bent valve. Not all vehicles will experience bent valves if the timing belt breaks or becomes misaligned. Reason It's Not a Major Overhaul: A bent valve occurs due to the breakage of the timing belt or chain. If the damage is minor, it may only require lifting the cylinder head to replace the valve, cylinder gasket, and timing belt or chain. In more severe cases where the piston is cracked or punctured, replacing the piston or connecting rod may be necessary, but a full engine overhaul is not required.
