Have Classic Car Questions? Ask an Expert.
Can you check the engine oil level please?
How loud is the ticking noise?
Is it a ticking, or knocking noise?
How many kms on your VE?
Does it matter which fuel you are using?
Could be one of a few things.
Timing chains, piston slap, big end knock.
Accessory pulley alignment, Power steering pulley is the cause.
Have you driven near a wall to hear it better?
Ok, so your noise is "pinging" under acceleration?
Very common, especially for VE.
I would recommend an upper cylinder clean using the Subaru product or Threebond product.
The carbon buildup within the combustion chamber increases the compression ratio, the PCM can't pull any more timing out, and hence the sounds you hear.
There is also a SPS program update for ECM.
I hope my advice has been of assistance to you.
Do you need any further help?
The programming is done at your local Holden dealer, I've done many.
