I also agree that the intake cam looks off by a tooth, I thought that before even reading matt's reply.

I think you should check your compression every time you change your oil if you run your motor hard. It doesn't take that long to do and its cheap insurance. This helps if you know how your engines compression normally check out, you'll be able to spot a potential problem easier. With that cam possibly being off a tooth it would also show on a compression check, as your numbers would be slightly lower for no other explainable reason. Usually compression numbers rise as an engine ages... to a point. Then they dwindle back down as the rings begin to stick/wear out.

Is the belt old? Have you changed your timing belt recently and ensured the correct tension is applied to the belt? Have you accidently over-revved your engine?

x2. up doesnt look like its exactly up.
