3ltr Diesel Tapping Noise
Hello i have the 3ltr diesel engine, it has developed a tapping noise. I have recently changed the oil but, i think the tapping noise was there before the oil change. i Have changed the oil many times before.
The tapping noise is not all the time it comes and goes. When starting the jeep its all quite. Often does it when warmed up.
i thought the noise is coming from the top end sounds like a hydraulic/ tappet lifter noise. The noise sounds close to rocker covers.
Do they have Hydraulic lifters? The engine has only done 125k whats not a lot.
what could it be.
