Finding TDC on a 7AGE

[oldeskewltoy]

I FINALLY got my hands on an assembled 7AGE and the owner allowed me to check TDC by using a piston stop. You CAN'T do cam timing... if you don't KNOW where TDC is......... well... here it is



Above is TRUE TDC... as measured by using a piston stop. 2 teeth off AT the CRANK!

I always figured that Toyota changed the position of the TDC dot on the 7A oil pumps and crank timing pulley. I figured (correctly... in many cases) that people had no idea where true TDC was because they were using a 4AG timing pulley, and using a 7A reference........

ahh good one. This should be added to the info when building a 7age.
