Hello house, kindly assist me make clarifications.
My Toyota camry 1996 engine number is carrying 2 engine number close to each other, an example below

4T1SK4ZE9
SU890966

I haven't had the time to do this checks, not until I was about to sell, worst of it is that the engine number on the paper is quite different from the above engine number, probably the engine was replaced. From the above which is the real engine number or the both are same
