Hi ,

I have a 2007 mini cooper - n12 engine and working on it now.

Timing chain failed and no compression on #4 cylinder , removed head and found this

I sent the head to a machine shop for valve job and
I just got it back and about to install it.

I put the timing tool and I noticed #4 cylinder exhaust valves are open.


When I firast removed the head with timing tool attached , I thought all valves were closed ?

Can anyone confirm #4 exhaust valves are suppoed to open with timing tool attached ?
TIA

 

This should be fine.

 

Thx
I just finished it up , adaptation reset , valvetronic relearn , vanos reset are all done.
Starts up fine with one code
2891 - DME : Inlet camshaft to crankshaft correlation

Can't find any more info regarding this code.

What is this code ?

 

did you clear the code and it returned? if so, did you make sure the vanos sprocket are on the right cam? also, check the timing one more time, it might've moved a little.

 

I am getting dtc 2891 - inlet camshaft to crankshaft correlation
Checked everything and all look good.

When I do vanos adaptation again , sometime the value is out of range.
After perform the adaptation , it runs nice and smooth.
Let it sit for a while and next cold start , it cranks longer like 4 -5 seconds then it starts with this code again. Dtc 2891.

 

Sorry I'm new with mini. how do I do this? adaptation reset, valvetronic relearn, vain reset are all done.

 

I used my Autel scanner , maxisys ms906bt
Ista or Inpa will be better choice but I have my scanner anyway.

By the way the problem was solved.
My amazon timing tool was not a such a good one , I had to retime it with feeler gauge.
there was a bit of slack at intake cam holder.
