Q: TAPPING NOISE IN ENGINE NISSAN PATHFINDER 2002 155,OO K

asked by on

LOUD TAPPING NOISE FRONT ENGINE - DECREASES ON ACCLERATION

My car has 15000 miles.
My car has an automatic transmission.

Usually, loud knocking noises from the engine are the result of a broken internal engine part or low engine oil. I would strongly recommend against driving the vehicle until the cause of this issue has been determined. I would first start by checking the oil level and topping it off if necessary. If the oil is low, I would then recommend checking for oil leaks with a fluid leak inspection. Once this has been done, resolve any fluid leaks by replacing gaskets and seals as necessary. If this issue is not related to low oil levels, it is very likely that an internal engine part is broken and a rebuild or replacement may be required.
