I will enter the study if it is still going on, although I am not sure if my engine has the original paint. I was actually looking here to see what color to paint my engine when I came across this post. my car is B382002229 LRXFE Jal 662244 engine number 7445 B19KC color code 86. This info is from my tac 936. not sure if the motor is original, maybe you can say when I give you the numbers.
