I believe that you are right: your drive belt is broken. Unfortunately, this happens to everyone at some point. The best course of action is just to replace the belt. I don't believe anything happened to any internal engine parts...
If there is engine knock after running low on oil and it does not go away after putting oil in it, then the damage is done. The engine bearings are bad and more than likely ruined the crankshaft, rods, pistons....
Hi there. The noise could be from the lifters not filling up with engine oil until the engine is warm or the pistons have too much clearance causing a condition called "piston slap". Check to see what brand of engine...
An engine is a large air pump. It is best to remove the spark plugs (https://www.yourmechanic.com/services/spark-plugs-replacement) and crank the engine over with the ignition and fuel system disabled. This will blow out all of the water from the engine. This...
Of course, first confirm that the plugs are correct for the engine. The wrong plugs, and/or missing crush washers, can cause interference with the piston. If the plugs are correct, the cause of the mechanical interference can sometimes only be...
Hello - If you have lost all the engine oil through the oil pan, there is no doubt broken internal engine damage. Most likely, this is a broken connecting rod (https://www.yourmechanic.com/question/car-knocking) or piston. Attempting to restart the engine would be...
The amount of oil usage you have would cause a large cloud of smoke out the tailpipe. If you see smoke out tail pipe then you most likely have piston ring damage and not sealing on piston walls. You should...
Hey there. In the context of engines, interference timing refers to the use of a timing belt rather than a chain (https://www.yourmechanic.com/article/what-is-the-difference-between-a-timing-belt-and-a-timing-chain), such that when this belt breaks, the camshaft and other internal parts (like valves) will cause major damage...
Hi there. It sounds like there could be a fault somewhere in the camshaft position sensor (https://www.yourmechanic.com/services/camshaft-position-sensor-replacement), crankshaft position sensor (https://www.yourmechanic.com/services/crankshaft-position-sensor-replacement), or engine computer circuit. Check all fuses and relays (https://www.yourmechanic.com/article/how-to-check-fuses-by-rocco-lovetere) and replace as necessary. The computer will not enable...
You may not need brakes but should get them inspected to see if they are worn down or just noisy. If you are having to replaced the brakes every 4000km or six months, then you have issues with the calipers...
Hello, thank you for writing in. When the engine is locked up, it means that it is stuck in place for one reason or another, and it will not rotate like it normally does. This is directly related to the...
Hello, thank you for writing in. Testing for oil burning usually means opening up the engine to see if the pistons and exhaust manifold show signs of oil. You can also check your spark plugs to see if there is...
Hi there. Check the spark plugs and make sure that they are creating enough spark to allow the fuel to burn. If there is great spark and the engine acts like it does not want to start, then there could...
Hi there. If you see a hole in the bottom of the engine and oil is coming out (https://www.yourmechanic.com/services/oil-fluid-leak-inspection) and the engine will not crank over, then your vehicle has thrown a rod due to hydro locking a cylinder. The...
Hi there. The noise could be a heat shield that is loose on your engine causing the loud vibration noise and it will appear to be a rattling noise. If the rattling noise is more choppy and not fast and...
Hi there. You will have to remove the timing belt (https://www.yourmechanic.com/services/timing-belt-replacement), exhaust manifold, intake manifold, all vacuum lines, the cylinder head, and the oil pan to gain access to the piston removal. Drain out all of the oil from the...
Fuel is introduced into the combustion chamber at the top of the piston and any gasoline found in the oil pan has to travel passed the piston to get there. The piston rings must be worn very badly and this...
The only way to determine the failure mode of the bolts is to send the "assembly" to a forensic laboratory equipped with a scanning electron microscope. If the bolts were loose, there would have been noticeable vibration and noise prior...
Unfortunately, there is no way to tell without doing some more testing (https://www.yourmechanic.com/services/car-is-making-a-noise-inspection). The timing and small details about the noises you are hearing may make a huge difference in diagnosing the issue. Lifters will make more of a "clicking"...
Hello. Oil can only get in to the cylinder one of two ways. Oil can get past the piston rings from worn or seized rings on the pistons. There is even a possibility of broken rings. The other way oil...
