""alternator bracket oil leak"""

Image and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicImage and video hosting by TinyPicHello everyone...
last week picked up 02 e65 with 120k miles...car is in pristine condition in and out...owner stated that his so called""bmw specialist"" has replaced alternator and t shaped gasket,so i took his word for it and my mistake...since it was raining that day i couldn't see any leaks and after scanning the car there were no present or pending fault codes except rear brake pads wore down to minimum...already ordered high perf drilled/slotter rotors fr and back with new pads...brought the car home and first thing in the morning i see oil leak on driver side...already knew its the alternator bracket oil leak
so instead of waxing and cleaning the flagship i started taking everything apart come to find out that guy has chipped of the water pump pulley,broken off radiator blade and few bolts missing.(will post pics and video later)...
ordered parts from dealer including newly rebuilt alternator 1130 plus tax and send my girlfriend pick up all the parts....including oil/filter...coolant..fan..pulley...she came home and baaam guy gave her air cooled alternator..called him back he said he made a mistake so ordered thewater cooled this time and only charged us 700
and today i am putting everything together.....
the threads on this forum helped a lot...since i only specialize in inline 6 and wasn't sure how this is going to go but its not that bad even if you don't have engine hoist or bmw special hoist....i will post pics and videos down the road...but for now all you need to do is release the driver side motor mount don't need to realease the passenger side,drop the powersteering pump but don't disconnect and put jack lift under the engine and lower/raise the engine it self depending on which bolt you are trying to remove from motor mount...be sure to put enough force so the torx socket is not going to slip after motor mount is out there is 17 or 16mm bolt holding the bracket and after that bolt is out bracket is out.....took me about 3 hrs to do it in my garage and by 3 hrs i mean just disassembly....after that washing all the parts from oil and cheking for leaks if any present but engine looks like new so thats good news....job itself is very easy and i couldn't believe dealer wanted to charge around 4k or more....gasket costs 1.40...
just take your time and its pretty forward to do even if you are not that technically inclined...
to me it doesn't make any sense why would anyone put a 2 small holes in the block that are hardly used here in states only used in gulf as oil cooling option but i guess designer didn't have anything better to do.....hopefully his kids are not working for bmw

hopefully ill get it done today....so in couple days ill post pix and videos

saturday installing brakes...last night bought staggered 20's with new tires for 500 so i should have the flagship on the road by monday..and finally enjoy her....

good day

Well I don't know weather to congratulate you or "PRAY" for you. To buy a 7 series with worn down pads, bolts missing an chipped water pump is enough for me to "RUN" as fast as I can in the opposite direction. As for oil leaking....well... maybe you could have let that slide . Your next worries would be that it's a 02, which was the 1st year they switch over to the E65, E66 body style. With that being said it is important to get that car with "ZERO" issues at time of purchase. Its apparent the previous owner(s) did NOT take good care of it based on what you said. If I were you I would be checking, actually replacing valve cover gaskets, Timing case gaskets, CCV, plugs, spark plug tubes, bushings, trans flush, check battery sense your already messing with the alternator, oil an all filters. Then go from there. There is tons of info on here which I see you are aware of. I wish you the best. Welcome to the fest.

thank you...i am not worried about the car...i scanned everything with my genesis tech force scanner and everything is good...history on the car was excellent until the last owner...he bought it not even a year ago and couldn't afford the repairs so he was trying to get rid off it and of course covered up the alternator oil leak and his specialist has done little damage to few parts...already have all new parts..good thing it started leaking the next day this way i am going over everything and fixing it....
transmission is smooth and strong but i will change the filter and fluid and check all the solenoids...my 02 525i with steptronic had 192xxx miles when i sold it for 9500 cash and tranny was mechanically perfect...only issue was trans fail safe but i found the problem to be egs not tranny it self after trouble shooting the solenoids,checking all the wires from and to egs and tranny and ground wires....after egs problem it shifted perfect not one dtc and talked to owner who bought it from me and he is happy with the e39....brakes are nothing plus i rather have drilled/slotted rotors than oem ones...they should arrive tommorow....there's one problem with logic amp one side of speakers is crackling but i will fix it my self...electronics is my specialty plus worse case scenario there are few on ebay for good prices....
suspension,bushing,balljoints are like new....timing chain covers were done and vcg were done too....so hopefully no more problems down the road and if they arise only thing i can do is fix em.....

good day

I have this job planned for when I get back home in a couple of weeks. As well as cyl 5-8 valve cover gasket. Did 1-4 last month. Hopefully 5-8 should be a bit easier.
I was gonna jack the motor up with a trolley jack as I don't have an engine lift either.
Did you have to remove the anti roll bar completely or just slacken off the mounts and tie it out the way?
I have dynamic drive but was just planning on taking the mounts off and tying the roll bar out the way.
Keep up the good work. I shall be watching this post with interest!!

btw how is your leak? is it bad or just dribbles slowly?
congratulations on vcg job....
i have a dynamic drive too but i just removed it with anti roll bar and tied it with zip ties and same thing with power steering pump......its not complicated just takes a little time for the first time as you try to figure out the best and easiest way to do it with out engine hoist and special tools.....actually i had a guy give me a hand since i was under the car and he was under the fender driver side turning the ratchet and i was holding the extension with e torx socket....those 4 motor mount torx bolts are the worst because if the socket slips then you have problems....i think its better if you have someone help you when removing those 4 bolts....i will try to post more pics and videos later on...good luck with your project coming up in few weeks...i am also interested and will watch your progress...good day

Thanks for the info buddy. It's leaking bad enough to mess up my driveway.
I'm stuck in Singapore until end of the month so will keep an eye on this for any more tips.
Cheers.

I just did this job myself a few weeks ago! Its a PITA to have done it for the first time. Next time it should be a piece of cake if I make it to a next time.

thats right its a PITA...btw did you use permatex gasket maker around the new gasket?? also did you just press the feed pipe back inside the alternator housing and water pump? i bought a new feed pipe and was thinking putting a little oil to make it go in easier...thx

Yes I still do.. Sometimes it works sometimes it doesn't. I believe the solder came loose or is coming loose that why I it works on occasions.

do the alternators have oil in them? I thought they were electrical generators with copper windings. Is the oil coming from somewhere else and dripping past the alternator?

no they are sealed and no brushes inside..different from air cooled alternators....oil is coming from behind the alternator bracket itself...t shaped gasket
