ticking noise

lifters possibly.

 

As above. Good chance its your lifters. This is often worsened with an aftermarked cam if it has an agressive profile. What type and grade of oil are you running? Running a different reputable brand or grade can often help this since its only intermittent.

 

My cars got a tick in the far left cylinder aswell haha. I suspected a lifter aswell, even though i got all of mine replaced with the cam install.

Check your oil pressures hot/cold in conjunction with the Holden specs

Check your oils etc.

If that's all good, (this is sourced from Steve @ Mace), he said you can cheat by putting a higher ratio rockers on as they put more force onto the lifter, which (in short description) stops the ticking.


^ I'm not too sure on that stuff though, you're better off asking Steve about that - So don't take my word on it.



I know this might sound weird, but it could be your injectors too.



edit: How many K's has your car done? If it's over 100,000 I thought running higher than 5/30 was more recommended. I ran a lighter oil in mine by accident, and it definitely made a loud ticking noise from the injectors. - Which got louder.

 

Just to elaborate on what DevilDRake's mentioned, you can also linish down the rocker pedestals or run slightly longer pushrods. This will put more lifter crush on the lifter, often curing a lazy lifter. I suppose it might be something to consider prior to changing lifters

Cheers,
Steve

 

My car has only got 95xxx on it

 

my ute does this i reckon its the hydraulic lifters it goes away after the oil pressure bulids up well 4 me anyway

 

it's the PVC

i bet it only happens when the engine is slowing down
if it were an engine problem you'd hear it all the time

 

Ah a cam, then you may need longer pushrods depending on the cam base circle (reduction in size)

 

It only happens when it is idle

 

Haha like mine, i hear it.. all the time.. With music and everything down obviously.

 

Yeah man thats wen u hear it bloody annoying
