I have checked the timing with a timing light and EGR
Looking at the front of the car, the engine would rotate clockwise. When I aim the timing light at the vibration dampner, I see 10 at the TDC mark (for the sensor) and the OT mark is to the left of 10. So If I am not mistaking: It's 10 degrees advanced Before Top Dead Center (BTDC). Is this within specs?
I have applied vacuum to the EGR valve and it holds vacuum good. When I pull the vaccum line, I hear a popping noise which tells me the diaphram is not raptured and the EGR is good.
