My cruiser is in pretty good shape with about k on the clock.

But it has a persistent piston slap in one cylinder. It's around miles each way, much of it on remote, hot highways and back roads no off road on this trip though. Does piston slap just slowly get worse over time until you have a constant loud knock with lots of blow-by or will it kinda go all at once right in the middle of the Mojave dessert?? Last edited: Aug 21, If it really is piston slap, then it could be fine for along time.

There is a big lawsuit with GM over the bad piston slap in their V8 engines. I have never heard a 2f having piston slap but guess it is possible with any engine. I would get an opinion from someone that knows engines and see how bad they think it sounds.

Is it a rod knock or piston slap? If you have piston slap you will have worn rings on that cylinder. Have you done a compression test? Rod knock would have resulted in a blown engine by now right? I did have a comp test done 6 months ago, here are the numbers: 1 2 3 4 5 6 Number six is where I hear the noise so it fits I have worn rings and a bit of slap going on. The latter is possible as the engine seized a while ago not sure why and I freed it by removing the head and whacking the piston crown with a piece of wood.

It worked! Bearings may also go, mainly because it's such a simple engine it doesn't have an oil sump. Any lubrication comes as part of the two stroke oil mix. Thus I don't think the rotating bits are ever going to be very well oiled. I appreciate that it's had a hard life, but it's essentially disposable so I shall buy a new one when it breaks. The question is how long can an engine in that state run for? It still goes fine, just sounds horrible.

Depends what it is. Some of the newer and faster cars have up to 12 chambers. Even though cars have many chambers, combustion can only happen within one chamber. There is a lot of heat created in the combustion chambers.

The pistons are lightweight so they can move easier. Nowadays, they are often made from aluminum alloy which allows them to move up and down the cylinder easier. Back in the day pistons were made from cast iron.

This material was used because it could handle the extra heat. Within this system, there are the pistons and the piston rings. If these rings start to wear out over time, you will notice that smoke will be emitted because they are starting to fail. Another part of this system is the oil ring. This part is a combination of two rings. It is used to wipe unnecessary oil from the cylinder wall.

If these rings wear out, oil will start to leak into the combustion chamber. This could lead to very bad problems in the future. If you have pistons that are failing, often your check engine light will turn on.

This will turn on to notify you that there is an issue somewhere throughout your car. If the car has a diagnostic system, there will be an error code.

This error code will help you detect what the issue is coming from. The error code will show which cylinder is misfiring. Sometimes there could be a false reading because of a broken sensor. These sensors are critical in telling the system whether there is an issue or not.

The sensors will notify the diagnostic system and then that system will turn on the engine light. Why do misfires occur? This could happen for many different reasons. Some of these reasons include bad ignition coils, bad spark plugs, a dirty fuel injector, or a bad spark wire. Those parts will cause blue smoke to be emitted by the exhaust system though. If this blue smoke is produced, it can be bad of the environment and bad for you to breathe in.

This smoke often has harmful gases. Snapped Timing Belt: Do you know what a timing belt is? The timing belt is a critical part of every car. It helps fine-tune the movement between the pistons and the valves. So you might be wondering what happens if the belt snaps? Well, the pistons and valves will crash into each other.

This is not good for your engine system. It will cause more engine issues and you need to get this problem fixed as soon as possible. Worn Piston Rings: Wear and tear occur over time with almost any part in your engine system. The piston rings will start to wear out over time if they have not been replaced or properly maintained in a long time.

When this happens, air will flow in between the spaces of the cylinder and the piston. Oil will also start to leak into these spaces and travel down to the firing chamber. If this occurs, this is very bad. The car will produce white smoke and take in a lot of engine oil. You will damage your engine system if you let this go on for too long. Always take your car into a mechanic if you notice an issue with your car engine.
