I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.
this car has a timing chain, not a timing belt, and issues with the timing chain are fairly rare. however, it should be easily confirmable with some engine tear down - either the chain slipped/broke and caused easily identifyable damage, or it didnt.
normally if the sensor is installed correctly and working correctly, you would get a warning if the oil got low.
Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
Thanks for your answer. I would also like to know If the oil sensor was not fit back properly what effect would this have on the dash computer? Would it fail to alert me if oil was low? Also would low oil cause the same engine damage as a slipped/broken timing chain?
Please do not forget to CLICK ON a positive rating. thank you
if the oil sensor is not working properly or not installed properly, then you might not get a dash warning for low oil. it will not have any other effect on the dash computer other than possibly not signaling correctly
low oil and a broken timing chain cause different damage.
Thanks again for your interesting reply. I saw the engine today and the technician said the engine damage was done on the top where the followers are (dont know what that means) and that the camshaft hit the metal of the sump and there was lots of broken bits. He said he had to now check the bottom of the engine to see where the problem originated from. From this information would you say this damage was caused by timing chain or lack of oil?
I would say timing chain issue but I can't be positive based on what you've stated
as the original question has been answerd, please kindly select a positive rating, thank you
Thanks again but apologies I still need to be clear, you say oil and timing chain cause different damage. What would those differences be?
if you had no oil the engine would roast and score and sieze and show signs of lack of lubrication
if the timing chain broke, there would be a broken chain for one, then benlt valves and damage to the top end
