Which cars have interference motors

The following lists will allow you to determine whether your vehicle has an interference engine or not. If the timing chain or timing belt breaks or gets loose, it will skip a few teeth on the crank gear or cam.

Suffice it to say that the rotation of both the camshaft and the crankshaft fails to synchronize. With an interference engine, a malfunctioned timing belt can cause the pistons to strike the valves.

This is because pistons will continue moving, which will most likely hit valves in a completely open position. Unfortunately, this scenario can damage the valves. However, the worst-case scenario is the possibility that the engine will get extremely damaged. If the timing belt or timing chain breaks, assess the damage as soon as possible.

Moreover, you can bring your vehicle to a car care shop for a leak -down cylinder test or a valve-gap check. In most cases, there is a bent valve if there is a large valve gap. You can also have your vehicle checked for cylinder damage. And if you bring your vehicle to a car care shop, the mechanic will use a borescope camera to assess your vehicle.

The camera will be inserted through the spark plug hole. Thus, this way, they will be able to check if there are damages inside the cylinders.

There is no standard repair process for bent valves. This is because repair options vary, depending on the type or severity of the damage. For instance, if the cylinders and pistons are damaged, there is no other option but to replace or rebuild the engine.

If the cylinders and pistons are in place, but several valves are bent, there might not be any need to replace or rebuild the entire engine. Instead, you can have the cylinder head rebuilt and the bent valves replaced. TDI 1. His high quality car buying tutorials offer help to the car buying public.
