Does this shop know what they are doing? There is no compression on any cylinders? Zero or just low? If there is no compression then I would say that the timing chain is not timed correctly. If it was too far off then they may have bent your valves. If you know the bottom end is good (pistons and rings) then they need to recheck that they installed the chain correctly and have everything timed right.
I was thinking about this some more. You bought the head new? This was with new valves and seats. If someone sent me a head that I had to take to a machine shop to redo I would send it back, like over night give me my money back. I'm not trying to be a smart a$$ but if they did that bad of a job on the head you don't want it on your car. I would not want to be driving down the road and one of the seats come lose. I have built many a engine and only one did I use a machine shop that did not do their job, it cost me a lot of time and money.
So some one does not know what they are doing either the person that built the head or the shop that installed it.
I guess the only other thing I can think of is somehow the head gasket got screwed up but no compression on any cylinders. something smells like a dead pole cat.
Let us know what happens, it may help another mini owner.
Actually Dave, he spent 200+ at the shop to find Nothing wrong with the Head, and had the shop re-seat the Head anyways.. then reinstall the head and still NO compression.
The cam phase will cause no compression in all cylinders.. he said the original problem was the cam .. I would check that before dissing on the already checked head work. BUT... this site will never change as long as the trolls are still here !
