Opel Zafira B 2006 Z22YH cam crank waveform

Post by liviu2004 » Mon Jan 06, 2020 7:43 pm

Anyone having a cam crank correlation waveform for Opel / Vauxhall Zafira B 2.2 Z22YH?
Cam is hall, crank is inductive. Not the same as 2.2 Vectra C waveform.

Have this car here with suspected jumped timing chain. Max cylinder pressure 5.8 bar, intake event at - 0.8 bar, big vacuum pocket by expansion phase.

Hi.
Here's for you.
Quite a high mileage car.
But the engine is working fine.
No error.
The vacuum in the receiver is fine.

Thanks, it helps, I can see the exhaust being 1 teeth difference, but I suspect intake cam to be way off, judging by the cylinder compression waveform.

Car is fixed, timing chain guides broken. Garage replaced the kit, engine runs fine now.
