ok spark plugs changed, now i didn't noticed the buging or misfire thing, i hope i will never do again, but when it was buging or misfireing it did felt less powerfull, once its gets hot then it feels less powerfull a bit, fortunetaly/hopefully the miss stroke is gone now, but i still thinking on the o2 sensor because the machine in the repair station showed that the fuel air mix was going up and down. so if its less powerfull when its hot is that the o2 sensor?
all spark plugs was kind of white.
idle good, runs good, but feels like something holds it back, just like a poor fuel mix...

i hope that im not annoying.

i might be working for this bmw garage in Spain in the near feature, where i usualy go if i need a press for bushings and things..... possibly doing the worst jobs, but it will helps the forum.... and my knowlage as well
i wish:)
thanks

you can messure voltage on sensor, but to be shure you need oscillograph. If you O2 sensor is completly dead you will see it with multimeter...

I had the same timing guide breakage.  Amazingly a piece about the same size ended up in the pan, it has to squeeze through a pretty small hole to go from the timing case back into the pan.

To get the big bolt off, I took a piece of 1/2 plate steel, drilled 6 holes to match the pully bolt pattern, bolted it on, then welded it to the engine stand, then to actually break the bolt I put my 22mm impact socket on the bolt to protect it, then used a big pipe wrench to break the bolt.  Impact socket ended up with few scratches, but nothing to major.
