Hey guys, i have a 1997, Jeep Cherokee, 2.4L Petrol Manual.

I was driving to the hunter valley from sydney, on the freeway going 110, started making this loud tick noise, sounded like the fan was hitting something, but i checked and nothing was there. After the freeway going 80 – 90Km/h it stopped. On the way back it started again on the freeway, but got louder the more i accelerated and going up hills. It kept doing it once off the freeway, then 15 mins later just stopped :S.

I then drove of 20 mins and started again just before i got home, then left it on idle and it went away :S

Oil, oil filter, spark plugs, were all done about two months ago.

Im not sure if it has to do with the engine getting hotter but i cant figure it out. Anyone have any ideas what it could be.

Regards in Advance.
