This is sensitive info bro.
Alot of ppl who know will not simply tell u this because of JPJ issues. Alot of JPJ officers don't know how to check and we want to keep it that way and you can be one of them (JPJ, digging info here) =-).
One thing i can tell you is, you cannot just "pop" the bonnet, look at the engine and expect it to be there. =-)
