2001 Jaguar XK8 car won't start due to possible timing issue
2001 Jaguar XK8
I set the timing according to JTIS
I have used the tools required and I made sure the VVT was fully retarded.
Car won't start. I removed the head cover and discovered the cams are upside down
Is this a bad VVT issue... How do I resolve?
Does anyone have pictures of what a fully retarded VVT looks like?
I have disassembled and reassembled this car so much I'm clueless on whats done right..or wrong.
Thx in advance for your help

The driver side cams don't rotate at all... Is this normal?

Kearnice, Do you think it may have jumped timing before you started with your repair. If so, then you could have low compression due to bent valves. Try the oil in cylinder trick and see if it comes up on the low side, if not , get the head off and verify what is going on. A new or used head would be much cheaper than a engine.

The engine over heated and "popped" 3 valve seats. I had both of the heads rebuilt as a result. During the several dis-assemblies and re-assemblies I got compression test results as high as 150psi on the passenger side so I think there's life in the engine IF I can get the timing set correctly. Its been a major challenge for me to get it right so far.

I put the VVT bolt back on and tightened it to 125 Nm
I then rotated the engine by hand to ensure the chains would eliminated slack but alas...the chains were off by one or two teeth.
How do I address this?

I rotated the engine clockwise. Two full rotations
This didn't appear to eliminate the slack
