I bought a used motor. I am replacing all the gaskets, water pump, and oil pump. I took the timing cover off and the chain is out of tolerance. I took the number one spark plug out and spun the motor until I felt pressure blowing up through the spark plug hole. I such a screwdriver down in the cylinder and rotated the crank to get it on TDC. The rotor is pointing at the number 1 on the cap. When I look at the timing gears the crank and cam are at the twelve o’clock position. Is this correct? And what is the deal with the 15 pin count.

What year? What engine?
