Hello everyone, i have a 2008 750i
I blew one/both head gaskets. i have called around and repair cost 6k ~ 7k.
90k miles
one suggested it's trash now.

i have worked on 60 and 70's cars but this looks like a wire mess. i don't mine working on the car. and know it's not going to be a weekend job.

i guess i'm looking for suggestions. should i fix/repair/junk

I purchased a online chilton repair manual. it's a worthless publication. example - open hood, disconnect battery, remove cylinderhead.

suggestions for a better repair manual

Blown head gasket usually means the cylinder heads are warped and need precise machining by experienced specialist. Rebuilding motor not cost feasible. Used 4.4 motors for around 2k can be found on ebay.

Thank you all for your Replies. Just for the fun of it I went to the BMW service dealer. 30K just for a new motor, Probably another 5k to install it.

I like the idea of purchasing a used motor around 2 to 2.5K. maybe another 1 to 2K to install.

Just curious if anyone knows if the motor is removed from the bottom or through the motor compartment?

Thank you for your postings. The service manuals are much better than the ones I have

A bit easier to drop motor from the bottom after removing the suspension component and subframe, disconnecting exhaust and hoses/wiring underneath with the car on a 2 post lift. That is how these is assembled at the factory.

To pull the motor out of the engine compartment is when you have no access to a 2 post lift. Hood, front bumper cover, headlights, ac condensor, radiator radiator support core, fan have to be removed. Then jack up the car to remove/disconnect component underneath.

So 2 post lift is a must to do an engine swap,
