hey guys,

i have been reading up a fair bit on how pinging/detonation works as a few nights ago....for the first time i took my car into the high rev range for one gear and noticed it was pinging... i nned to know...this is the first time i heard this but i have seen that by the time u hear it, it is to late... this engine has 60,000km on it and i put it in no longer than 1-2 months.. i have not gone past 3,000rpm since this happened... and have booked it in to be tuned and so forth...but..... is it all

No. Your engine can still be healthy. Constant pinging will kill your motor. pinging on the odd occasion/one off pinging like what you have done is not good, but it probably didn't do any serious damage either.

Get a compression test while its getting worked on/tuned, too see if the engine is still healthy just for peace of mind. Just don't let it ping again.

just a quick question guys

what does pinging do to the engine?

hey dude... umm pinging goes hand in hand with detonation.... its when the compression in the cylinder is to great and is exploding b4 the spark and therefor settin things of as the piston isnt ready to take the blow.... ( im pretty sure).. pinging ruins your engine if u consistanly bang it... can go from busting up the rings to melting a piston ( im pretty sure again)

so guys.. from what i have told u... is the car stil drivable ( when i say that i mean i will granny it hard).. or should i just not drive it again until the tuner has a look??.

thanx for the quick replies guys.. apprecciated

engo

its best not 2 drive the vehicle unless need 2. if u need 2 drive it then baby it so it doesnt get 2 the stage where it starts pinging. also with pinging or detonation it is when the air and fuel ignite b4 the spark ignites and if bad enough can try 2 move the piston in the oposite direction and after a while weaken the conrod and worst cum 2 worst the conrod snap and end up through the block.

I've got a question sorta on the same topic here.....

Is pinging the same as KNOCK, measured by the powerfc?

I think i've heard my engine ping, but when i check my powerfc, the max knock was only 20. So would i be hearing ping, or something else?

pretty much theyre the same thing....... but the knock sensor WILL/CAN pick up other noises.. not only knocking.. iv heard many times the knock sensor picking up other rattling sounds coming from the engine... and it would give false alarms to the pfc..

also, it is very hard to hear an engine knocking...... unless if the levels are 80 or so..

its possible that youre hearing some other noises.. maybe misfire?
