how do i take out these 2 bolts? i cant move these metal pipes and they make it impossible to get to, im changing the timing chain gaskets on my 2008 550i.
#how to get bolts out

i can sort of tell whats going on bu not really
if those metal pipes are coolant lines you can probably get away with disconnecting them but youll have to do a coolant flush
if they are AC lines DO NOT TOUCH at all costs doing an AC job is the last thing u want to get involved in
i also cant tell what head the bolts have, if they're an E-Torx then you might have to get a special tool (e-torx wrench), but if they're the standard hex head then u should be able to get a wrench on it
you might be able to snake a wobble extention through there if u try hard enough, look for a service manual for a timing chain job or a tutorial video

Spot on, couldnt have said it better

Yep those are e torx, and they are quite easy to shear. Make sure you have full contact with the bolt before turning and use a penetrant oil of some kind.

GG @wind sinew, you just advanced to level 2! Chat more to level up and earn top roles!

And use a mirror or a camera to make sure there isn’t a lock nut in front of the lower bolt.
hollow sinew
And its the timing chain cover gasket?
yes

all extensions won’t fit we ordered a torx wrench, we were gonna disconnect them and flush coolant but i’m not sure if they actually are coolant so ima leave them
wind sinew
Can you loosen the alternator tensioner to push it out of the way a bit?
So you have more space
hollow sinew
yea i already loosened the tensioner and moved the alternator out of the way
wind sinew
I might try to run a socket extender past all the stuff to the other side of those pipes/tubes, or use an offset adapter
hollow sinew
even my e torx nut is too big to fit in there by itself only thing that we’ve gotten to fit is a wrench
i might order an offset adapter and try that though

Is this one of those instances where disconnecting some motor mounts and lowering the engine will help? @hollow sinew
Do the steel lines go to the block?

You should definitely follow those hard lines to see what they are, so you can at least establish if disconnecting them is an option
What gonzo points out is likely, although I have that same concern, the lines might move with the engine and you’d be in the same spot

it might help but i’m doing this in my garage and don’t have anything to do that with
the steel lines go and curve around and under the block, they aren’t connected that i can see but the only way to move the engine out of the way of the pipes would be to lift it out the car

tutorial video doesn’t have any problem getting to the e torx bolts on the side of the cylinder head on the passenger side
Driver side he just slid the alternator out the way and used an extension

Possible a wobble extension might do?
Gives a small amount of pivot at the end which might be all that is needed

this is the video i was following
he doesn’t show him unscrewing those 2 unless i just haven’t pushed the alternator all the way out of the way
managed to get a bolt out but hopefully these pictures help with showing how stuck it is
i can’t push the alternator further down i just redid the steps and it’s still in the way
and the 2 pipes do connect into the engine block as well

Ur gonna have to remove that line, whatever line that is, pray to god it’s coolant and not AC, or push it out of the way as u unthread the bolt by hand
hollow sinew
yea i might have to or im just going to have to figure out if i can remove the cover with the screw in by just slipping it out
only thing is is that i have to torque it down when putting it back on but its only around 7.5 ft lbs so that shouldn’t be hard
hollow sinew
just figured out they are ac return lines

Bruh ok do not touch them and find another way
