Timing won't lineup

niifio · Post by **niifio** » 07 Nov 2016, 13:08

Have turn engine clockwise 3 times with timing belt untouched but timing marks will not lineup. I crank the car and it runs great. Timing marks are M and ^. Need help to change the timing belt.

Hi,

I don`t know what engine is on your Volvo, but check this video maybe you are missing something.

Are you talking about your '02 S60? If so, I believe it has a single VVT hub. You can also refer to my PDF for guidance on timing alignment which is a compilation of details from several sources. My PDF is targeted towards a dual CVVT hub setup, but the principles can easily be applied to a single VVT hub arrangement.

Finally got to read your write up on dual vvt hubs, wish it had been available before I did my cam seals, very good clear cut directions.

Thanks. I just tried to compile all the useful info I found helpful to me while I was in the mode of a vertical learning curve regarding the VVT hubs.

Have turn engine clockwise 3 times but timing marks won't lineup. Crank car and runs great. Don't know what to do. Have watched the timing videos. Any advice why the timing marks won't lineup.

eXACTLY WHICH MARKS DONT LINE UP.?
Are the 2 cam marks in sync with each other but out of sync with crank are all 3 out of whack with each other.
The crank pulley is keyed but the cam pulleys are not keyed .

Also, exactly how far off are the timing marks, try to be specific, one tooth off? 5 teeth off?
What is your history with this car, who did the belt previously.
