Alternator bracket oil leak

Has any been able to replace the gasket behind the alternator bracket by simply removing alternator. Also bolts that hold braket on may be loose, so does anyone on here know if bolts are accessable by just removing alternator. ? Thanks in advance.

Most likely if your gasket is leaking, it is not a loose bolt. One of the bolts is behind the motor mount bracket. The bracket along with the alternator, power steering pump, & fender well must be removed. You are looking at around an 8 hour job. The good news is that the gasket only cost 1.50.

Just finished doing that as part of a crossover pipe replacement (weep hole problem). Fun stuff...it's cramped in there, but at least you have the air-cooled alternator.

You have to remove the alternator, unbolt / move the power steering pump (to get it out of the way and take weight off the bracket), lift the engine and unbolt the driver's side motor mount. Then, you will be able to remove the alternator mounting bracket.

Found my leak. Upper timing cover is leaking. Does anyone know if I need to remove valve cover first to replace this seal

Thanks

Here is the TIS. You should not have to remove the alternator bracket.

+1 on the TIS...but the link to the DIY does not go hand and hand with the E65/66 models. Almost but not quite same.

looked like a whole lot more room on the e46 pics,it took me 2-3 hours to get the last two bolts out (top front of bracket and 1 behind motor mount)just couldn't get a tool on them,car was on axle stands,a hoist would have helped.I have the TIS but the theory is quite different than the practical and here in n.z. you can't just go down the auto store to hire a special tool (bmw) for fan clutch.

Personally has stated this job 3 time and only on 3 time I was able to remove bolt holding engine mounts. My advise do not take anything out prior removing 3 bolts from underneath.For this u need take driver wheel off and jack the engine from the bottom just little to take the pressure of the bolts. You can reach them using u-joint and different extensions also u need 10mm (i may be wrong on size) star socket . I have air cooled alternator. If u have the same than u do need to take a fan and steering pump container out . It is straight forward job,but time and nerve consuming job.

can i drive my car out of town until i the alternator bracket gasket,vacuum pump and oil pressure switch replaced. the dealership said that it would be fine. just make sure my oil level is good in my car,which i keep a check on it. i dont have oil leaking on the ground anywhere but i do have to add oil like every month to a month in a half to my car.

Yes should be fine just keep checking your oil each time you stop.

I started removing the engine mount bracket put can't take it out. It is loose so I will try to remove the one large bolt that is holding the alternator mount in place. Do I need to remove the fender or lower the subframe in order to be able to get this job done? Thanks.

You can take the inner guard off,it helps a little,guard and subframe can stay on.
all the bolts need to come out of the engine mount so you can move it out of the way to get to the bolts behind it that hold alt bracket on.I removed the 1 top bolt if you look down between the engine and the guard there's 1 torx bolt.then you can jack up 1 side off the motor to give you more room,check the DIY section(Wilson009 and Keif) good write up and photo's

Alternator bracket oil leak

Thanks. I will do that tomorrow. Very tight in that area so I was just checking to see what others did. I have the motor mount bracket off after trying for two days. Now I only have the last 16mm bolt left to remove. Hopefully I can put it back up without issues. I am taking my time since I am not in a rush. Thanks to all you guys for always posting very good information. I will post some if my pics soon.

I am half way through this job. I finally got the last bolt off today and sprayed brake cleaner to clean up the oil all over. I will start reassembling on Monday. Hopefully it will be easier to put things back together than taking them apart. I have some pictures I will try to post.
