Hello.
Take a compression test on the engine, these are the results:
Cilinder 1: 220 psi
Cilinder 2: 216 psi
Cilinder 3: 220 psi
Cilinder 4: 220 psi
The nominal pressure for this motor (5A-FE) according to the workshop manual is 14, 0 kg / cm2=200 psi And the minimum of 10, 0 kg= 142 psi.
Could this 20 psi difference cause the spark knock?
