Ttick, tick, tick from the engine
 

As pevious posted under: Hammering / knocking noise on 4.0L6 '99 Cherokee
it seems, I am much closer to finding the source of the noise now.
For the last hour, I have spent listening to the engine at idle,
air-con and auxiliary fan off..
No mistake, the noise is coming from the engine, around
cylinder 5 or 6. The noise is also clearly audible around the
left wheel house.
It cycles on and off. It goes like: tick, tick, tick....increasingly
loud for about 10-15 seconds, stops completely with a few
seconds silence in between, and starts again. The cycle lengths
are not completely even, with variations of within a few seconds.
Some cycles are louder, some cycles softer, and sometimes, there
is a longer brake in between the cycles.

What could that be?

Thanks again. I feel, I am much closer to solving this riddle now.

Regards,

Robert

It sure sounds like you have a lifter that is not staying pumped up.

I don't mean to insult your intelligence, but, do you have air conditioning?
