Broken Hub Tab on e46 M3

This white convertible belongs to a fanatic and is based in Tzaneen.

Car came in for the normal vanos and rattle kit repair and valve clearances.

We started off with doing valve clearances before moving to the vanos work.



Interesting deformation of non OEM air filter.

Head ready for final clearances.
You will notice that the retainers have been removed and as we finalise the clearance we re insert them.
We are simple folk and anything that can make life easier and not confuse us is welcome.

Clearances finalised and retainers inserted.

Unusual dirt on vanos unit. Our suspicion that the base plate seals must have had a leak were subsequently confirmed.

On removing the vanos unit this is what greeted us.
I was absolutely in a state of disbelief......I have read about it and have seen pics of it however I did not expect to see one this soon.
Clearly the oscillation that occurs with the tabs does put them under extreme stress and it then becomes a matter of time before something gives.



Oil pump disc which we will save by re drilling.
