Oil pan

Hello, So all of the oil leaked out of my car via the bolt you take off to change oil. I changed it last week and I could see it leaking gradually and I just kept topping it off. However I finally got to the bottom of it this morning. It appears that the oil pan bolt or the treads it's self are stripped. As it will not tighten all f the way. I dunno what would even cause this. However, I am going to replace the entire pan. has anyone had experience with doing this job? Is it a tough one to do or is it pretty much self explanatory? Any input would be greatly appreciated. thanks guys.

In the inadvertent how NOT to change oil thread, you can see what a bolt looks like.
- Cn90 How to change your oil; and Bluebee how NOT to change your oil!

BTW, it's unlikely it's stripped if it's a BMW bolt because the BMW bolt is DESIGNED to shear before it will strip anything.

The most likely explanation is a crushed crush washer...

Maybe you can supply a picture or two?

If it is stripped, there are heli-coils and other insertable thread inserts which are simpler than dropping the pan (dropping the pan on an I6 is a very difficult task ... easier on the V8 apparently).

Mine has no washer. I was wondering if that was normal or not. But, it does appear to be stripped considering I go to tighten it down and all it does is spin freely with no resistance.

Sounds like some neanderthal was working on your car in the past. Yes, it should have a crush washer.

First, I would verify that which threads have been compromised, the bolt's or the pan's. If it is the bolt then a new bolt with crush washer and your done, if it is the pan then you have a bit of a problem.

If the pan is stripped out then you can either over size the hole by tapping it out and putting a larger bolt in or you can run the same size bolt by using one of the various repair kits.

Looks like you need a socket for the filter cap, 32 mm, as I recall. Sears, or a well-equipped auto parts store.

What happens when you spin it counterclockwise?

Does it spin out?

If so, take a picture and post it for us to help further.

PS: Edjack ... I didn't understand your response ... you referred to the oil filter housing socket size ... but he has problems with the drain bolt.

ashton540,

You may very well end up pulling the pan. Good thing it's a slam-dunk on the V8. Check the oil pump nuts whilst the pan is off.

bluebee,

look at the oil filter cap, it's all boogered up. Someone has been using Channelocks on it!

My filter cap nut is 32mm. This is a new-to-me 1999 528i and the filter cap has apparently been removed via channelocks during it's life....new one is on the way.

Bummer about the broken drain plug.

I just did my first oil change on mine yesterday and what a cake-walk......easiest and simplest oil change I've ever done.

Oh my! That's MY oil-filter housing (OFH) filler cap you're talking about! < eyes look to the floor in embarrassment >

I've since bought a 36-mm socket to spare the OFH further damage!

+1. Start with a new bolt and washer from the dealer. If it is the pan, I would recommend a timesert over a helicoil. I always keep a spare oem drain bolt for my cars. If I ever slip and bugger the bolt head, I simply toss it and install a fresh one, they are cheap. Never used a torque wrench on it, though I own one....just tighten until I feel the copper washer start to yield, and stop.

BTW, if anyone needs that 36mm socket, BMW Seattle sells them for only $14 or there about. I'm cheap, I just use a rubber strap wrench similar to this one...
http://www.northerntool.com/shop/too...6401_200306401

I got a set of four, two large and two small for like $5 from Harbor Frieght Tools or some such...keep one set in the kitchen for stubborn jar lids.

That will work on the V8s...but the E39s with I6 engines can't. Their oil filter reservoir is kind of "recessed" and surrounded by other stuff that makes it difficult or impossible to use a strap wrench.

Just an FYI...didn't want I6 owners to run out and buy one, then to be sorely disappointed that it's going to be a struggle to use it.

(note in image below: the oil filter reservoir is recessed and surrounded by the power steering reservoir, engine, and fan shroud....making it nearly impossible to use a strap wrench)

Interesting observation.

I was wondering if the 32mm/36mm fan-clutch wrench would work but probably would suffer from the same access problem as the strap wrench.

The good news is that the local AutoZone store had the 36mm sockets in stock for about 10 bucks IIRC when I needed it.

BTW, it cost me $10 at the San Jose BMW stealer for the M12x1.5x18 "screw plug" (PN:11131273093). Do we have a cheaper source for them online?

To the OP ... you never answered the question (AFAIK) of whether or not you can spin it counterclockwise to spin it OUT to look at the threads. The reason it matters is it's practically impossible to strip a BMW bolt ... trust me ... I've tried!

So instantly I was a bit concerned. It did this over the next few days but, I just kept topping it off because I just had zero time to deal with it. So I finally had some down time to deal with it. I loosened it up and the re tightened and it never got tight and, continued to leak. So I am just probably gonna buy a pan from a salvage yard. I don't feel it really needs to be new considering they are over 200 dollars new. I just wanted to verify it was a pretty simple job. Doesn't seem to difficult. I'm hoping that I can just get a gasket from advanced auto parts. The bolt btw was the one that came with that car but doesn't look like the ones that you all posted pictures of. And it also came with no washer. Which seemed odd to me.

Try a new bolt and washer first, it might correct the issue. Everytime I removed or installed the bolt on my 540 it felt really wierd like it was cross threaded or something and would alternately feel a lot of resistence, then very little. On my third oil change I finally replaced the bolt, and amazingly all was well. I was advised by a tech that the threads on the bolt had probably stretched from someone previously overtightening. The bolt usually gives up before the pan. So I would recommend giving it a try before thinking you have to replace the pan or install a Timesert. Timesert would be your least expensive way to fix http://www.timesert.com/ http://www.timesert.com/html/mtrcsert.html they are very strong and durable. Better than a helicoil.


BTW, 540 drain pan bolt is shorter than the one used on the 530. Not sure why.

Like I said, the BMW bolt is practically hollow. It would be hard to strip the oil pan with a BMW bolt because it's designed to snap off if you try.

Now if it was a different bolt ... well then, it might be easier to strip the oil pan threads. Are you able to back out the bolt to confirm that the pan is what stripped?

What did you think of the thread inserts suggested?

I've learned, as has everyone who lives near San Jose, that the dealer here on Stevenscreek Blvd charges double or triple than even the other stealers do.

So, the ONLY time you go to the San Jose BMW dealership is when you have no other option.

In my case, the bimmer couldn't move until I added a bolt ... and they charged ten dollars for that bolt. They also charged 65 dollars (plus 10% tax) for the upper radiator hose when OEM BimmerParts sells it for about $20.

Lesson is that the stealer in San Jose is even worse than the stealers everywhere else. Last I checked their hourly rate was something like $200/hour (but I'd have to check that to be sure).

I will be driving to the stealer this monday to get a bolt and try that before replacing the whole pan assembly. This sucks bc I have to e39s. and they are both broken down. My 03 525i has a bad clutch and will not move anymore. Great timing huh?

I'm slightly confused although you are pointed in the right direction that a new bolt is the simplest solution, if it works for you.

Do you think the stripped threads are on the oil pan or on the bolt?

If you think it's on the oil pan, then the new bolt won't help (you'll need to clean up the threads with an M12x1.5 tap or use the appropriately sized thread insert).

If you think it's the bolt itself, then the new bolt will solve your problem.

Which do you think it is ... the bolt or the oil pan? (pray it's the bolt)

BTW, while you're at the stealer, consider getting:
- Oil filter & 91x4 O-ring & A12X17-CU copper crush washer (Mann, Mahle, Hengst, or BMW P/N 11427512300)
- Optional: (1) oil pan drain bolt (M12x1.5x18, BMW P/N 11131273093)
- Optional: (2) oil filter stem o-rings (7x2.5, BMW P/N 11421744001)
- Optional: (2) dipstick handle o-rings (9x2.2, BMW P/N 11431717666)
- Optional: (1) extra copper crush washer (A12X17-CU, BMW P/N 07119963151)

So i did figure out that the bolt and pan are both stripped. However, i did notice that the oil sensor is placed directly next to the drain plug. I may just wend over the plug and just drain oil for the oil sensor from now on as opposed to buying a new pan for almost 300 dollars. I do not see any complications with this aside from have to unscrew 3 bolts to drop the sensor opposed to just undoing the drain plug. Am I wrong here? Seems logical and fast to me.

If you rather not touch the oil drain plug any more, consider buying one of those oil change pumps that suck the oil via the dipstick hole.
