Hi bro...
Does it sound like a ticking watch? or more like a dropped marble?
And I take it that its only audible at idle...?
Would be good to let us check it... better be safe =)
Take care!!

Hi Edric, that the pinging is only appear when my engine is warm up. Your team have commented that it could due to valve lash is slightly tapping. Can you advise is it dangerous and not good for engine?

Can you advise is it dangerous and not good for engine? Hi bro, yea my mechanic told me about it. I wouldnt term valve lash as dangerous but it could ultimately cause the valve oil seal to start leaking. It is indeed not ideal for the engine but the cost involved in removing the cylinder head and measuring all valve stems costs alot.. (same as a top overhaul) Thus, it may be more cost effective to monitor engine oil levels. And if sounding gets worse (valve stem rattles) then do a top overhaul. Meanwhile use nothing lower than w40 engine oils to ensure proper lubrication. Its just my 2 cents. Dont flame me please!!

Dont flame me please!! i have been using Amsoil 5w40 EO. need better oil? the tap is like 2-4 tap then pause and not continous tap. however, when i rev up a bit, the engine do not have irregular tap. just only on idle. oh ya, i did some carbon clearing last wednesday, rpm 3k - 5k for 15-20min. after i reach my carpark, the idle sound is good not tapping. can advise?

Hmm heat from your carbon clearing process would have expanded the valve stems... on minor stages it would have been enough to get it to a nice size to sit nicely.. thus no sound lor... Your amsoil is good enough... =) Remember to monitor it and see if the tapping sound gets more frequent or louder... Cheers and drive safe bro!!

Wah seh!! Bro Devilcup introducing full multimedia vehicle diagnostic method! Although the recording not very clear... but the continuous kuah kuah kuah kuah sound is normal... the random occassional tick tick tick is very much like tappet sound... so yes i think my mech is right... valve not opening and closing properly / loose in its guide... It sounds damn loud... maybe i turned my volume too high... hmm.. well continue monitor... everynight drive home... nice and hot... come out of veh listen for awhile then kill engine... Any louder or more frequent then its time to come in... Meanwhile save up a little bit of money i guess..
