ur timings off the blocks timing doesnt match ur heads timing so the valves open up as the piston comes up and hits the valve

How does an engine exhaust valve get bent?
the valve bent because the piston hit it, due to a weak valve spring or over revving the engine
What if valve on a engine is not flush?
you could break the valve on intake or exhaust stroke top of piston could hit it
Is the 2.4 engine in the 2004 PT cruiser an interference fit between the valves and piston?
Valve to piston, no. The interference is valve to valve.
Do valves hit pistons in sportage when timing belt breaks?
No they don't . Mine broke on my 2001 sportage and didn't do any damage. This is due to the fact that the engine is called a "non-interference" motor. At no time can the valve hit a piston (in theory) because the valve travel is not enough to ever hit the piston.
Is the sorrento engine a noninterference engine?
An interferance engine is typically described as an engine with a valve assembly where, the lowest point of any valve's extension into the cylinder, is lower than the highest point the piston will reach. If valve timings are altered incorrectly or a valve spring breaks, the valve and piston can collide, causing massive damage to the engine.
Can a timing chain make an engine lock up?
Uh, yeah. If it skips when a valve is open the piston can hit it, and it'll either break the valve or not, but if it doesn't, and it hasn't hit TDC it'll lock up.
Is a 2000 Dodge Dakota 3.9 liter an interference engine?
Yes, they are an interference motor. the intake valve will hit the piston at full lift and tdc.
Why does a car engine burn oil?
bad piston rings Excessive engine wear - Rings, Valve guides, Valve seals
Why would and engine lose compression?
Valve, valve spring, piston, piston ring, cylinder wall, head, headgasket, diluted oil, stuck injector,
What is zero clearance engine?
In an engine, the piston's go up and the valve's that are adjacent to that piston go up. When the piston goes down the adjacent valves go down. This is achieved by the timing belt or chain and the engine timing being set correctly. If the belt or chain breaks, the pistons still go up and down, but the valve's stop moving. On a non clearance engine, the piston will go up and hit the valves, resulting in bent valves and a now needed head job. In a clearance engine, the top of the piston has an inset cut into it that is just enough room to avoid hitting the valves.
How do you fix valve slap?
Do you mean piston slap? Noise like piston slap are repairable only by an engine rebuild.
Why deflected shape of piston in 2-stroke engine?
In a 2 stroke engine the piston itself is the intake/exhaust valve, instead of having separate valves as in the 4 stroke. The odd shape of the piston is the location of these valves.
