Hi everyone hope you are well,
I am having a hard time diagnosing a rattling/ticking/pinging sound from my engine bay, honestly not sure if it's the engine or something else. Noise is hard to describe but imagining a ball bearing bouncing around on metal is pretty close.
Hard to get a video but can try if necessary, here are my observations so far:
- Currently 231k kms, last serviced 229k kms (3 months).
- Not sure if noise has been happening since I got the car, but have noticed it for at least 3 years (about 30k kms)
- Noise occurs in any gear, but most noticable in 4th and 5th
- Sounds like it is coming from directly in front of drivers seat as opposed to in the middle where the actual engine is, but this is just a guess
- Intermittent sound, best way to reproduce is to apply 50-75% accelerator while going up a hill. Less than half or more than 3/4 the noise seems to go away. (However, noise has rarely come during WOT and while engine braking (3k RPM 3rd gear) down a hill.) Keep in mind that there are times when I can apply any throttle setting and hear nothing.
- Noise isn't linked to any particular RPM range, however seems to quieten down past about 4500rpm
- Seems to only occur while driving - can't reproduce while inspecting engine bay.
- Other than this sound, car is running perfectly
- Acceleration doesn't seem to be affected while noise is happening
Things I've checked so far:
Air filter (changed 3 months ago)
Throttle body (cleaned about 10k kms ago when diagnosing misfire)
Spark plugs appear to be all good (about 12 months/8000km old)
Coil packs working normally as far as I can tell (I don't have a scan tool or any CEL)
Valve clearances checked and adjusted 3 months ago
Suspension and engine mounts were checked just after I serviced it 3 months ago.
Only other info I can think of right now is that I run car on 91RON and I've been averaging 8L/100km since I started keeping track. The noise also used to occur when I ran with E10.
Any insight would be appreciated, if I've missed anything please let me know.
Thank you in advance
