I think i will purchase a screw extractor set and see how that goes. I mean, it cant be such a bugger can it? Its a small bolt :eek:
 
yup, i got a blowtorch handy.
Got myself some mole grips, some magic juice and some screw extractor just if they come in handy.
Ready for the job today, but might need to let the magic juice do wonders first.

Magic juice= not vodka :rolleyes: It is some quite expensive stuff in order to loosen up theese sort of issues
 
And don't try to turn it out from the start but use a"rocking" turn between loosening and tightening if you know what I mean, soaking the threads while you turn so the oil gets down the bolt. Difficult to explain but hope you understand.;)

understood.
Its actually what i did, but the bolt didnt feel like having it.

So today it will come out screaming soaked in magic juice.

Need a new bolt tho. Is there a special part number or is it just to go into any hardware store and buy exact same bolt?

The part number isSTC2347 it's a flanged head bolt but any M6×25mm bolt with a washer should do, copper slip the threads when reassembling.;)
 
Don't the threads go into a cast iron engine block?
idk, isnt the bmw m51 (2.5dse) aluminium? the whole shabang? I'm very unsure as i cant really tell the difference between 20 years old greased up aluminium and cast iron. I dont sit with to much knowledge, barely know what im doing :D

I've drilled trough the bolt, and have soaked it with some magic juice and will tap in one of theese special hex stick and screw that thing right out (hopefully) btw, can recommend the Milwaukee M12 FDD-0 it drilled quite nicely trough the piece. (also drilled my new thermostat (bleed hole, at 4.5mm 12o clock), and checked that it worked in a pan of water, this one opens at 79degrees and also opens abit wider i'd say than the old thermostat.

Forgot to say thank you @tomcat59alan for the bolt partnumber! so thank you for that! :)

it also seems like the old thermostat had a oneway valve mounted 12 o clock, whilst the bleed hole (someone had drilled it previously i see) was 6 o clock.

I hope it goes well tapping in the rod thingy and extract the remains, with hopefully undamaged threads. If not i must probably drill with a slight larger bit and use a bigger bolt, but i guess that aint the end of the world/engine...

Cast steel crankcase :)
 
Well, plan didnt work so used a bigger drill bit and went over the threads. About a milimeter or 2 to go and it should fit.. might just chop off some of the bolts length tho
