My new ae86 (with a 1st gen map sensed 4age 16v) is making unhealthy noises above 3500-4000rpm.
It's somewhere between a 'whirring' and a 'pinging' sort of noise. if i didn't know better i'd say it sounded like a rattle, but it comes in consistently at the same engine rpm every time, and i'm worried. I know what 'knock' can do to an engine, and i dont know whether this is knock or something more harmless. someone told me it was the valve clearances needing adjusting, but my mechanic reckons the valve clearances are fine.
if it IS pinging, what can i do to solve the problem? the engine is unmodified, and i didn't do the swap from the 4ac myself.
i've been made aware that intake temps can induce pinging, and i've been thinking that a cold air intake can't hurt, (probably help a fair bit actually)... any other suggestions?
I'm already running on BP ultimate (98RON), so an increase in octane is probably futile.
another suggestion is that it could just be a bearing somewhere.
Ideas as to what this could be?
