that is a 1.8L DOHC with HLA, Lifters they usually only click at first stratus, or if oil pressure is low.
it not put in any additive to oil. vast type, who knows what's in it, and the flush is usually just kerosene.
if oil has been super dirty, over 5k miles, then id replace it twice, do it now, then at 3k. see if fresh top quality oil can not clean the HLA'S?
i ask my self what can i do to the top end with out putting mains, and rod bearings at risk.
if it is HLA, noise, and not a bad chain tensioner? Then the HLA gummed up. Most that are , are R&R fix out , apart cleaned, recharged with oil and back in. (big job)
or its pinging, under load. (EGR dead + lean mixtures) i dont think its ping. (knock or detonation)
ive never seen HLA make noise under acceleration. (as hot oil fills them with max pressure, how could they, this condition, is best, why make noise then>) i think its not.
i dont think its ping.
the 1.8 has a knock sensor, and usually prevents all ping , it corrects it long before the humans can hear it.
Is the oil fresh?
is the CEL on , key on, then goes out running?
Scan it, are there zero DTC's stored and running? some DTCS dont glow the CEL, in some countries, so best scan it, regularly.
I think you hear the chain talking, does it make wild noises at cold startup
also it has a hydraulic chain tensioner that the piston inside can leak more , hot, and cause it to fail hot. in fact adding that engine flush will make this worse, (bad idea that)
is the accel, noise there cold?
finding a noise , that only happens moving, is the hardest of all.
got over 200k miles on that chain?
