Engine has tapping noie. sounds like valve lifters
(1) Answer
A tapping noise from the engine can be from any number of causes, ie: piston slap (excessive clearence between piston and cylinder wall), lifters, injectors, carbon buildup on piston tops etc. I suggest you take your vehicle to your local repair facility for inspection and diagnosis. here is a link to shops in your area: http://repairpal.com/directory?address=95304&car_brand_names=Jeep
