Will a motor run with bent valves?
Will a motor run with bent valves?
A bent valve could start a fatigue crack in the stem and if it breaks you drop the valve in the cylinder. if the valves are not bent that much, then it can still run with most likely not much problems. If it has bent significantly, it wont run right and can possible break off if it hits the piston and drop the valve.
How bad is a bent valve?
If an exhaust valve is bent or damaged, it will no longer be positioned correctly in the cylinder and the valve head may not create a pressurized seal when it is closed. This will cause an exhaust leak that will almost certainly affect fuel combustion.
What happens to the timing chain on a 2.7 car?
An incorrect repair can disturb this timing and cause the valves to open down into the cylinder while the piston is moving up through it, striking and bending the valves (besides other damage). The 2.7 engine has both the timing chain and the water pump on the inside of the engine.
What happens when the timing belt breaks on a car?
Interference refers to the fact the intake and/or exhaust valves occupy the same space as the pistons. The timing belt/chain keeps that from happening at the same time. If the timing belt or chain brakes, the valves and pistons will hit each other. Valves can bend and/or break and the pistons can be damaged.
What should I do if my timing chain broke?
If the pistons are not damaged, then the least expensive route for repair, would be to replace the entire cylinder head with a rebuilt one as it is less labor intensive than rebuilding your existing cylinder head. If the pistons are damaged, then a complete remanufactured or used engine would be the least expensive route to repair the vehicle.
When to replace timing chain and water pump?
So if you notice coolant on you garage’s floor or if there’s lots of black gunk on the AC housing and the oil pan then it may be time to replace your timing chain and water pump. When the engine fires, it spins the crankshaft located at the bottom of the engine.
