my 2004 745 i has 104000 miles, starting leaking oil, the dealer mechanic said they found a crack in cylinder head on right,tried but could not close or seal it, and said need replac. e cylinder head for $$$$$. They denied damaging it while doing other repairs in same area
Car drives ok so long i put quart of oil every few hundred miles( initially every 600,now every 200 miles!). Any advice or thoughts why it happened and how to fix, other than replace the cylinder head for $10000 !!:

u can get a WHOLE used motor for under $10K

i am sure u can source a source a head from a junk yard for under $1000 or around there. whatever. still not $10k!

and u can find somebody to put it in for another $1000

edit: found a cylinder head for $439 with FREE shipping

but its the left side, dont know which one u need!

Thanks Seven11! Unfortunately I am not much of a DIYer... so if anyone knows of any good/reputable mechanics that can do the cylinder replacement in the inland empire region (SoCal)I am all ears.

Thanks again for your help!

No Problem!

any good mechanic should be able to change a head for abut $1000 or less.
