1999 S70 T5 CVVT Question

[bmdubya1198]

My cousin's 1999 S70 T5 has been down for several months now. We originally had to replace the timing belt because the water pump went out, and now it's escalated to the CVVT being the issue. After doing several different things to try and get the car running again, I've narrowed it down the the CVVT.

After reading around, I decided I would check alignment of the camshafts from the rear of the engine. When I removed the rear cap for the intake cam, everything was properly aligned, as it was on the sprocket. On the exhaust cam, however, it was about 90 degrees out. I turned it to where it should be, and I noticed that the sprocket did not line up properly. I wasn't too concerned about that at the time.

Anyway, I hadn't given it much thought before, but there is a "click" sound coming from the exhaust cam, and you can feel it in the wrench when turning the engine. After I aligned the cams, I turned the engine by hand again, looking at the rear of the cams. When it clicks, the exhaust cam clicks back a little bit.

So after reading around some more, I think the CVVT needs to be reset. I was looking at this procedure here...

Will this work? Obviously, someone had removed the exhaust cam before, probably to replace the cam seal. I think it was a combination of their shoddy work and my cousin and I turning the engine back and forth while replacing the timing belt and components.

My next question would be, after locking the camshafts and removing the CVVT hub, should I replace the sprocket/CVVT hub so the factory mark lines up with the notch in the engine cover, or should I make marks like this video and put it back how it was? Would it hurt anything to do that?

I would be more worried about bending valves if the cam timing was set up that far out, use the locking tool at the rear of the head to lock the cams and put the timing belt back on correctly once you have the lower crank pulley timing mark aligned.

The marks on the front of the cams pulleys don't really mean much if the cams and crank are locked in the correct positions..

The car hasn't been run since the timing has been out. The car was running fine up until we did the timing belt.

We still need to get the cam locking tool, but I had aligned the cams from the rear of the engine, and that's how I noticed the exhaust cam was "clicking" backward every 1/2 revolution or so of the motor. I made sure the crank was aligned as well, and it has been every time I have adjusted everything.

So, I assume I should just leave the sprocket how it is, and make my own reference marks?
