UPDATE: Variable valve timing head replacement, how hard is it? V70-XC70 2007

All,

I've finished this job last night and there is much rejoicing.

I took my time in getting the timing right.

The first attempt had the crank being off by 1 and half teeth after I spun the engine twice by hand, the CAMs however were still dead on, though I wasn't happy them as they were not quite where they should have been.

I removed the belt again, reset the crank correctly, while the CAMs were still locked and did the belt a second time. This time everything was spot on. I rotated the crank twice and everything was exactly where it should have been.

I finished installing everything and started the car.

It took awhile, about 15 seconds for everything to finally fire up, but when it did it just purred like new. I was impressed and now look forward to getting it on the road and really usable.

I want to thank all of you who aided in this endeavor. Without your knowledge on the dual VVT, I may have bitten more off than I normally would like to chew. Having the CAM locking tool was key, and it made all the difference in the world in putting the valve cover back on, and Jeffs suggestion of not removing the hubs and just placing the seal on before you put cover on and not after, was also a great suggestion. Normally I would not have done that as its not the correct way of doing it, however I do like to work smarter and not harder, and this way was definitely smarter as I saved a lot of time getting them on vs. pressing them in.

Once I get around to it, maybe this weekend I'll post some pictures of the car now that its running.

Regards,

Matt
