The automatic timing advance unit is a component in vehicles with diesel engines. Of course gas and diesel engines both work on the internal combustion principle, but they are quite different,...
Are you familiar with the EGR (exhaust gas recirculation) system in your car? If not, this is something all modern cars have. The purpose of this system is to greatly reduce...
In order to help reduce the amount of engine emissions cars have what is called an EGR system, which is an exhaust gas recirculation system. The way it works is that...
Hello, thank you for writing in. There are several issues that would cause issues while reversing and in drive. Start by having the vehicle scanned for diagnostic codes. This can be done at most automotive parts stores, or it can...
Codes do not conclusively identify faulty parts. Any part referred to in a code that is suspected of being faulty must be separately tested, that is diagnosed, in order to determine if in fact there is anything wrong with the...
Hello, and thank you for writing in. A knocking noise may be coming from the engine or the exhaust. Without pinpointing the exact location of the repair, it is very difficult to compare your options truthfully. An exhaust leak will...
Coolant leaks can be external or internal. If the coolant is leaking internally into the cylinders or crankcase, that will require a fairly significant repair. If the coolant is leaking externally, unless the leak is at the head gasket or...
The noise will be identifiable, and the origin pinpointed, if you request a vehicle noise diagnostic. Ticking noises are usually due to valve train problems and, in turn those problems can be caused by low oil pressure. Knocking, if from...
Hi there. Depending on the sound of the knocking noise and where the noise is coming from on the engine will determine if the engine needs replaced or not. If the noise is near the top of the engine, then...
Hi there. It sounds like you may have a serious issue starting with the engine. I would check the level of the oil first. If it is very low then that may be the cause of the noise. If the...
The knock sensor is located on top of the engine beneath the intake manifold which must be removed to gain access. With regard to diagnostic trouble code P0325 that code does not mean the knock sensor has failed. All that...
Hello. Most of the time this is caused by an issue with the timing chain or chain tensioners. The front of the engine would need to be disassembled in order to locate where the noise is coming from. Most of...
Typically, if a short circuit occurred while replacing the battery, or the battery was installed (momentarily) with reverse polarity, or wires were left disconnected, all of the resulting electrical problems, that is the ones you are observing, would be present...
The noise that you are hearing from the engine could be one or more lifters ticking. The lifters use oil from the engine to create a hydraulic pressure in them to keep them in contact with the valvetrain. If the...
The noise that you are hearing could be one of the rod bearings are knocking in the engine or the flex plate could have a loose bolt making the torque converter bounce around. I recommend seeking out a professional, such...
Hello. There are a lot of things that can cause this. If vehicle was having trouble getting to that speed then it may be a transmission issue or it can be something like a catalytic converter that is failing. If...
Hello. I would start by checking the engine oil level and pressure. Typically when this engine makes a noise like this it is due to a failure in one of the rod bearings or in the valve train. If the...
Since you were running your engine low on oil you may have damaged all the crankshaft and camshaft bearings along with piston and cylinder damage. You would need to have the vehicle inspected by a mechanic like one from YourMechanic...
Hi there. Wen the engine was overfilled by an additional quart of engine oil, then the engine was trying to lock up as the crankcase pressure was too high and the pistons are pressing against the oil. I recommend draining...
Hi there. Grab a flashlight and look under the vehicle for where the coolant leak is coming from. Either there is a gasket, hose, or freeze plug that is leaking causing the coolant to leak or the engine has cracked....
HI there. There are different symptoms that create smoke that emits from the tail pipe. Here is a description of the different smoke for you to check: Smoke Types Blue: Blue smoke is an indication that the engine...
