Hi you all!
Got the oil pump pulley problem, and bought me a BGA replacement (with more "meat" on the pulley axle).
However, I don't see how I can remove the pump cover from the engine.
I've removed 8 bolts and 2 bottom nuts, and have some play to the right (driving direction), so the gasket glue is cut.
But, on the crankshaft I can get some vertical play, the oil pump though will not allow vertical play
Do I have to remove half the engine block, since the M6 threaded bottom pieces won't bent, turn or come out with a double nut locking?
As I see it, impossible to get vertical play, and almost impossible to get lateral.
Help!!

Hello, where you removed the bottom nuts from underneath you also need to remove the 2 studs on which the nuts where on... ideally you want 2 new ones, those studs screw in to pump cover. A small mole grips can do the trick to get them out but obviously some damage will incur on the thread of the studs where the nuts used to be. For resealing the pump cover, would be a good idea to drop the bottom oil pan also... and reseal bottom pan after pump and cover fitted. It all depends of your experience not to have leaks afterwards. Note: removing the oil pan you will need new engine oil. Both oil pump cover and oil pan are fixed on with silicone rtv.

I removed the whole bottom, since the stumps were not willing to to come loose. And the engine sump needs no wiping :) Just normal engine oil, no debris, no sludge. After 410.000km that is assuring.
Now what I'm wondering, anything against using bolts instead of the stubs? Making things easier probably prevents the trouble from repeating, #Murphy'sLaw

Unless you know what your doing i would not modify that... you risk overtighten the bolts and crack pump housing. I spent some time thinking why is like that and if you look at the studs... you realize why...
