Engine stalls and serving tick over 2.5 diesel

ANSWER : If the ticking sound seems to be dependent on temperature, I might suggest taking a look for an exhaust leak somewhere. Small exhaust leaks will normally begin when cold and diminish as the engine warms, but in my experience, I have seen exhaust manifolds and pipe connections that will respond in the opposite, like you are describing. I’m not sure if this is the case in your situation, but it is another credible place to look.

ANSWER : This may be an issue related to what is called an idle air control module. This is a module that regulates the amount of air that is allowed into the intake system as it is mixed with the fuel before being injected into the motor. When this is not working properly, this will cause the car to stall as you describe. I would suggest having an expert from YourMechanic come to your home to definitively diagnose the stalling issue and make necessary repairs.

ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

ANSWER : About the only safe way to see if and how it runs, would be on an engine run stand.or engine dynomometer. Something an engine rebuilder may have. They would set the engine up on the stand, connect power, fuel, cooling, and run the engine. Try an internet search for any local shops that have a dyno or run stand and ask how much they would charge. Find out how the engine was stored. It should be treated the same as if it were still in the vehicle and the vehicle stored for a long time. Oil should be changed. A little light oil squirted into the cylinders through the spark plug holes, cranked with fuel and ignition disabled to allow oil to circulate before starting. Things like that. If you are going through a private seller, you may not have any recourse if something happens once you buy and install it. Going thorough a salvage yard may get you at least a short warranty and they may even cover a portion of the labor involved to swap the engine again should it have issues.

ANSWER : Hello. If the Check Engine Light has come on, then that means the computer has detected some sort of issue. I would rescan the computer to see if the same code has returned, even after cleaning the sensor. If cleaning the MAF did not clear the code, then it is likely that the MAF sensor needs to be replaced. When changing out the MAF be sure to replace it with a high quality unit (an original equipment piece if possible), as a low quality,or low budget MAF can sometimes cause issues. Usually a MAF sensor replacement is quick, and aside from clearing the code, it can help keep the vehicle running at maximum efficiency.

ANSWER : Hello, thanks for writing in. I would check the engine oil level and level sensor first as low oil will cause the engine to cut out. If the oil is fine then it sounds like a loose sensor connection. The most common one that would cause this is a bad crank sensor. There are a number of other issues that can cause this so it needs to be checked right when the problem occurs to see if it is losing power to the ignition or fuel systems. If you are going to have this stalling problem checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

ANSWER : Hi there. If the crank sensor is used only for misfire detection and NOT spark timing, the vehicle should start and run with the engine light on. Usually the crank sensor or the reluctor ring may have been damaged and needs replaced. The reluctor ring could have missing teeth or sheared off the key-way. The last thing that would cause this is a short to ground or the ECM has a failure. Check the crank sensor and make sure that the harness is plugged in. Check the reluctor for any damage to it. Replace what has failed. If everything seems to be working correctly, then check for any loose grounds that could cause a battery disconnect to the computer system. If all wires are good, tight, and clean, then the ECM may need flashed (reprogrammed) or replaced. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from YourMechanic, that can assist you with your vehicle not starting.

ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service.
