Isuzu Rodeo 1993 - 188,000kms Loud ticking noise from engine Worse when cold Oil pressure starts high at 4 (loud tick) drops below 2 when hot (softer tick) Tick goes away over 2500revs but comes back when it changes gears and drops revs. I ran low on oil recently but had a service last week and used high mileage oil.

a very common problem with these engines is a clicking sound in the engine, it can be a slight annoying click, to a loud knocking sound. I end result is usually the same, replace your timing belt and tensioner. I researched this problem when i bought mine, and it was knocking. i replaced the timing belt, (which was loose) and actually took the tensioner apart and cleaned it (not recommended for the mechanically challenged). new tensioners may be tought to find. when i put it all back together, it ran smooth and quiet.

I definitely agree with badmartian thats the same exact thing my trooper does. Our ticking was loud and obnoxious by the way embarassing when going through parking lots. Anyways I did some research and was thinking of a valve adjustment but cant since troopers have hydraulic lifters so the best way was to try to clean the gunk off these things. What I did was put heavier oil in the car 20w-50 but you can go with 10w-30 if your not to sure. Then add a bottle of Lucas Oil Stabalizer which runs around 7-8 dollars a bottle and a high mileage oil filter and that will seriously stop the ticking well it did for me for around 2000 miles and come back which means another oil change. Or you could do what I do and add another bottle of oil stabalizer not lucas maybe a smaller bottle like STP runs about 1-2 dollars and that should run your oil a bit longer. But yea when you change oil I suggest you adding Lucas Oil Stabalizer works great for me Im still using it and its cheap and you get alot of it for half the price of other ones. So yea good luck

SOURCE: I had the valve cover gasket changed on my 1996

on a v6 ? Low on oil? rear cam plugs leaking? The lifters are on the end of the rocker arms and may get clogged. I have had some luck running 0w30 mobil synthetic for about a week or so with a new oil filter [Not a fram filter] and after that put 10w30 synthetic oil back in and a new filter. Check for oil leaking at other locations. If the noise is at the front of engine near water pump it may be the hydraulic timing belt tensioner.

low oil pressure is causing your ticking. oil pump pick-up screen may be clogged
