I have a rvr x with a 4G63 engine in it lately there is a noise like top end so all i do is not runing it cold over or close to3000 revs ones it is warm 2000 the oil pressure light is not coming on or flicking it is on when i start the engine im not so familiar with this motor so pls help

Low oil pressure will make hydralic lifter tick (which comes from top end), so it would be consistant with your other symptoms. You need to figure out if your oil pressure is actually low.

But these engines are not known for loosing oil pressure, so I have no idea what could be wrong.

How many miles on this engine? What oil are you using? Have you changed the type oil resently?

the engine got 234,000 km on not alot what makes me thinking the lifter s i did check there i am sure its not from them the noise is coming from lower on the gearbox side of the motor oil i changed to multi grade i dont know what for one was in before i dont have the car so long

was just thinking about the balancing shaft where is it driven from and what kind of bearings it got in any help pls

These engines have two balance shafts, they are both down at the bottom of the engine. A front balance shaft is driven by its own timing belt/pulley set-up, the rear balance shaft is driven through an oil pump (the timing belt sprocket on the bottom right, as you look at the front of the engine).

Balance shafts spin 2x the speed of the engine, so their bearings fail fairly often (much more often than the regular bearings), especially for people who like to rev their engines high (above 5-6k).

To check for this failure, you will have to remove your timing belt, so this isn’t an easy thing to check…

thank you alot i will check there around and will let you know since i am in botswana i dont want to start stripping before i got some spares what are most properly the cause of the proplem so i am not getting stucked with a half stripped engine
