How do I know if my engine is non-interference?
The difference between an interference and non-interference engine is whether there is a gap between the valve that is fully open and the piston that is in the top position. If there is a gap, the engine is called a non-interference engine. If there is no gap, it is an interference engine.
Does the Miata have a non-interference engine?
You should be fine. It’s non-interference.
Do BMW’s have interference engines?
technically they ARE an interference motor- but normally have no symptoms like that except…..
What makes an engine non-interference?
Put simply, in a non-interference engine, when the piston is at top dead center (TDC), it will never go higher than a fully open valve; that is, the piston can never “interfere” with the valves. Conversely, in an interference engine, the piston could occupy the same space as an open valve.
Can a non-interference engine Bend valves?
non-interference engines. A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt, but the engine isn’t likely to be destroyed.
What is the difference between an interference and non-interference engine?
An interference engine is a type of 4-stroke internal combustion piston engine in which one or more valves in the fully open position extends into any area through which the piston may travel. By contrast, in a non-interference engine, the piston does not travel into any area into which the valves open.
Do Miatas have interference engines?
The Miata motor is a non-interference, the valves don’t reach the pistons.
Is BMW M54 an interference engine?
Yes, it is an interference engine, but no, you don’t need to worry about it. Timing chain and it’s designed to last the lifetime of the engine.
Is BMW n52 interference engine?
Your BMW has an interference engine, which means if the timing chain were to fail for any reason, you would have catastrophic engine damage due to valve to piston contact. Everything you need to service your timing chain is included. …
Can a non-interference engine bent valves?
How do interference engines work?
What happens to Pistons in an interference engine?
Interference engine animation. In an interference engine, this can cause pistons that are still moving due to inertia to hit some of the valves that are in a fully open position. If this happens, the pistons can bend or even break the valves. In some cases, an engine might be severely damaged as a result.
When does a non interference engine stall what happens?
A non interference engine “Also Known As A Free-Running Engine”will stall if a timing belt breaks; but further damage might be limited. When the camshaft turns it opens and closes the valves. The valve has to close and open at the exact moment when related to the movement of the pistons.
Are there any Honda engines that are non interference?

What kind of engine does the Eagle Talon have?
All 1G Talons built after April 1992 received a freer revving “7-bolt” engine borrowed from the 1992 Mitsubishi Lancer Evolution’s lighter rods and seven-bolt crankshaft. The Eagle Talon was consistently featured on Car and Driver magazine’s Ten Best list for 1990–1992. The Talon Turbo was on Car and Driver magazine’s Ten Best list for 1989–1992.
