More info : The engine was built a few years ago by an engine shop. The engine is in the car. I am looking at what is coming up to the rockers. Confirmed that the rockers are installed correctly : the rocker arm notch is toward the front of the car on the driver side and toward the back of the engine on the passenger side. Ran a small wire down the oil passage... it didn't go down easy... Thanks!!! Will check out the info provided later...
