Exclamation Oil Pan Gasket replacement question?

I got a 1999, 528i, E39. about 190km

I recently did my oil on it, about 4k ago, and my mechanic noticed a leak in the oil pan, and from the looks of it the gasket needs replacement. Now it's time for new oil, and a gasket replacement. There is a sub frame that runs across the gasket. I got couple questions regarding the installation process, need some helpful advice. My hands grow out of right places so I know my way around the car/tools, going to be a DIY for me.

1. Is there enough clearance between the sub frame bar, and the oil pan, to just slide the pan out? Instead of lifting the engine.

2. If not, I know I probably going to have to lift the engine an inch or two, I got access to a mechanic shop where I work(dealership) , so I'll take it there to work on it. As for lifting the engine, what do I have to take out, (shroud, fan, radiator houses, what else?)

3. Any tricks of the trade would be greatly appreciated.

The morale of this lesson is: if you think you have a leak from the Oil Pan Gasket, think again!
I thought I had the oil Pan Gasket leak, it turned out the leak from the Oil Housing Gasket and the 2 "Freeze Plugs" in the back of the Oil Housing:

http://www.bimmerfest.com/forums/sho...d.php?t=414315

PS: Replacing the Oil Pan Gasket in the 6-cylinder engine is a bear (dropping subframe etc. very labor-intensive; in contrast the same job is a piece of cake on the V8).
So I'd suggest that you do the the Oil Housing Gasket and the 2 "Freeze Plugs" first.

SOMAXIM,
Did you change your oil pan gasket? If you did please tell me how you did it since I have to replace mine and would like to know if it it feasible for me to change it myself. I am good with cars but on the BMW I always have afterthoughts.
Any help will be appreciated.

How many miles do you have?
Make sure you go over my post #2 above.
In my case it was not the Oil Pan Gasket but rather it was the Oil Housing Gasket.

Ya make sure you do what in post #2 says, i am doing it tonight. Also tighten the bolts arround the oilpan, sometimes one could be loose, as well there is a power steering hose with the connector right near there, tighten it up, mine was leaking and dripping on the oil pan, as for lifting the engines it's not that simple and you do have to lift it up inch or two to replace oil pan gasket. MP ill help you out with what i know.

1. Yes, do the Oil Filter Housing GASKET, it is cheap $5.

2. And No, be very careful tightening the oil pan bolts, very easy to strip them!
Look up the torque values and use a torque wrench.

My best advice is read post#2 above, then follow it up with checking for oil leak. Don't tighten the oil pan bolts YET!

You have to flip PAST the first page of results.

That's the whole point. I can do the search for you, and I'm sure I'll find an oil-pan gasket R&R, but, YOU are supposed to do that search first.

My suggestion is to do the search (and read past the first page of results). If after a half-dozen pages you still don't find an oil-pan gasket R&R, then it does not exist (or, you'll need to THEN ask for help).

Personally, I'd be shocked if you don't find one there (I glanced at the results and saw what you're talking about even before I posted that link but that is what searches are all about).

I repeat:
If you don't find the DIY you need, I'd be very surprised.

OMG seriously! the only write up is for a 540i. if you spent so much time writing all of that and doing a search on your own then send me the link. Dont automatically assume i didnt search. I searched OK! I didnt find anything so i asked. The only result that would help at all is for an e46 and even that one isnt clear enough for me to want to attempt this.

Im not incompetent so dont treat me as such. if you dont want to answer my original question just dont bother writing anything at all and let someone that does want to help me with my problem help me. Dont try to school me on how to use the internet ive been using google since 96' and trust me im no amateur at this. Furthermore if you consider yourself such n expert at googling you wouldnt include the year in your search because it just gives you useless results. The correct search would be "e39 528i oil pan gasket diy".

Thank you

I found this from cn90 in seconds with my google search (there were more but let's start with this); does it help you?

See also the attached BMW TIS for my model year car (yours is there too but I only downloaded mine).

This is from M52 Motor for E46 so you can get the idea:
http://forum.e46fanatics.com/showthread.php?t=665810

STRAIGHT Fromt Mitchell Repair Book:

Thank you this does help. I went through the results on your search (9 pages worth) and still didnt see that result. But anyway. Is this doable without having a hoist?

I personally, had oil pan leak for last year, wanted to do it, but never got around to do so... from the research that i have done, and mechanics i talked to all suggest lifting engine an inch or two, however everyone who i asked wasn't 100% sure. As for BMW dealership mechanics they said that they don't replace oil pan gaskets, they are made so that they don't leak, and if they do it's just a drop or two. I got 210k on mine now, and the leak is the same as when i bought the car. All i did i started using a bit more thicker oil, which helps with leaks, as well i tightened the nuts on the oil pan a little (MAKE SURE TO USE TORQUE WRENCH) or just very lightly 1/10 of a turn at most, not to over tighten. small leaks are fine, honestly the oil level stay exactly the same from oil change to next oil change, i lost like 50ml tops.. prob not even. Now if it is leaking like crazy then you would have to change the gasket, but it's a headache.

I see this in the steps:
"Attach Engine Holding Hoop (00-0-200) and Sling (00-0-204) to engine carrier. Raise engine as far as possible"

This intimates a hoist isn't needed so much as an engine sling. Presumably you can jack the engine up a bit before you sling it (because it will settle I would guess).

I've seen those inexpensive steel rectangular hollow bars that slide inside one another with legs on the end where you can hold up the engine with a cable - they might work.

Still, you should heed cn90's word ALWAYS since he's one of the best of the best here. At least consider doing the OFH gasket first and see if it fixes anything.

CN90, i have replaced the oil housing gasket, as well tried to do freeze plugs, they looked bone dry to me, as well they are different from the diy from post #2, so i didn't bother doing them, As for oil housing gasket i agree with cn90 it does help, however didn't fix my problem.

Your car is 1999. The "freeze plugs" seen in my DIY applies to only 1997-98 cars.
So you are OK.

There is a beautiful picture and list of all the steps necessary in QSilver7's location of an online BMW TIS for the E39 (1).

I don't think even the mechanics get anything better than that complete description for removing and replacing the oil pan.

For people who wonder what this job (replacing oil pan gasket) entails, this is a DIY from a 3-series but also using the same M52 motor.
The 2 major items are:
1. Engine Hoist to support the engine when the subframe is removed.
2. Subframe removal is a major PITA.

Here you go:
