Knocking sound from the engine but it stops every once in awhile
My car has 175000 miles.
My car has an automatic transmission.
Most of the time, an engine knocking issue is caused by low oil pressure or low oil levels causing metallic components to hit each other without proper lubrication. It could also be caused by loose cylinder head hardware, such as intake valve guides or rocker arms that are loose. The best way to know for sure is to have a professional mobile mechanic complete a car is making a noise inspection.
