United-States No compression on all four cylinders

Could the timing being off result in no compression on all four cylinders?
I have done a leakdown test ( all valves are holding air ).
I bore scoped the engine ( no signs that the valves have hit the pistons ).
Car ran fine until vacuum pump seized up on start up. Replaced seized up vacuum pump. And no compression from then on. (2007 mini cooper base model N12 engine)

I would be thankful for any input!
Thanks

Hi, I would think that the seized pump stripped some teeth off the timing belt, and so retarding the cam timing. You could do a rough check by looking at the valves when no1 cyl is at TDC. Either no1 or no4 should be on the rock.

Tosh, Thanks for the input. I did purchase a new vanos exh sprocket( this sprocket was on the camshaft attached to the seized pump, It looks fine but could be damaged inside). I read that you align the arrows on these vanos sprockets with the cooper colored links on the timing change.
The problem is that the new replacement timing chains are all the same color.
Can anyone tell me how to line the INT sprocket and the EXH sprocket up????

Help would greatly be appreciated!

Thanks Mini People!

Hi ya

You will need the special locking and setting tool to set up your timing correctly.
