I was recently talked into inspecting a co-worker’s 2008 528i. During the inspection, one of the issues found was a leaking oil pan gasket.

Based on what I saw (and the info online), it appears that I will need to support the engine from the top and also lower the subframe in order to remove the oil pan bolts. The book time for the repair is 5 hours, but most shops are asking for 7-8.

I will be using a new OE gasket and installing new bolts. I plan to buy a new angle torque wrench and properly torque the bolts to the 8nM + 90-deg requirement.

Can anyone provide some tips on this job? This is new territory for me.

Thanks

wonder what the in germany euro price is? id there a short cut?

I once had an izusu sedan, dealer showed me the the factory service said to remove the engine from the car to replace the timing belt. thats what it said.
went to chevy dealer who sold the same car as a spectrum, they said they just took off a motor mount after putting a jack under the oil pan> gave plenty of room.

You may need external torx sockets if you don't have them already.

what are your plans for holding the engine up? since you are going to be underneath it, you probably don't want a HF thingy to hold the engine up! Is somebody buying the tools?

Yeah, that's the part that I'm still undecided about. Book time says 5 hours, but no one wants to charge book time for it....which leads me to suspect that it's a bigger job than advertised. A local indy wants $1k, and the dealer wants $1550. The dealer did say that he can do the pan and the bushings ($900) in one day....which leads me to believe that the 5hr estimate is attainable by someone who does 'em all the time.

Good point, I don't have those. Thanks!

The torque spec on the bolts (as posted in the other thread) is 8nM + 90-deg for the short bolts. I don't see any angle torque wrenches that go this low.

As Trav smartly suggested, I'll just use my in-lbs torque wrench and get it to 70 in-lbs, then I will use a sharpie to mark the new screws at 12 o'clock, and turn them to 3 o'clock.

Just out of curiosity, how many miles on the car and what is the overall condition?

I also have an '08 528i.

The car had 183k on it. It's pretty much original all around, at least according to the owner.

The owner is not much of a car guy so I doubt much has been done to it. He did mention changing some coil packs and repair a leak in the valve cover and oil filter housing gasket. I think he follows the 10-15k intervals per BMW.

Supposedly the car consumes a decent amount of oil now so he wanted me to fix the oil pan leak...but judging from the size of the leak, I doubt that's the real problem. Perhaps that electronic dipstick has gone bust? LOL

Diff and transmission fluids are original. Drive belt is supposedly original but looks surprisingly good...but it's probably EPDM. Cooling system is original.

The shocks are probably getting tired, but there were no leaks that I could find. The tension strut bushings are moderately torn, so I am getting a new pair of arms from the BMW value line to replace them. He complains that the front-end is a bit loose and there's a shimmy at highway speeds. I told him that we'd start with the worn bushings and re-evaluate after.

Haven't looked that closely at the rear-end yet.

On the electronics side, I think everything still works, but there is a TPMS fault.

What is preventing the guy (or you) from re-torquing the pan bolts? Or it was already tried and given up? What size puddle are you talking about under the car when parked overnight? Is there any redneck solution with specific type of miracle cure or epoxy to stem off the oil leak?

The biggest question is though how in the world a premium 2008 car ends up with this symptoms which are reserved for 15 year old jaolpies? In my neighborhood, that is a practically a brand new car!

Welcome to the world of BMW. They've been using some inferior gasket material for many years (not sure if they still do), that results in frequent oil pan leaks, oil filter housing leaks, valve cover gasket leaks, rear main seal leaks, rubber gaskets around windshields disintegrating, etc.

It's really inexcusable, IMO, but it continues to happen. frown

But we are talking about TheCritic here. So I suspect, by oil pan leak, he really means that he found a drop of the oil on the edge of the oil pan and has convinced his friend to fix it correctly :-) No sane person is going to spend thousands of dollar to fix minor leak even on a newer BMW without exploring other alternatives.

It's leaking a good amount. The undercover is all wet, and there's pretty much oil all over the rear portion of the pan (side that faces transmission).

In fact, I wouldn't be surprised if there's also a rear main seal leak.

The bolts are aluminum and one-time use. I ain't touching them.

It's why I spent $3 on a plastic tray that I park my car over in the garage. It was either that or $1000+ for a rear main seal job. smile

European cars like to mark their territory.

Its not a leak unless it makes a mess, a couple of drips a night isn't worth fixing.

Even for an European car, this is way too early unless the vehicle has already over 250K miles.

How many days/weeks/months would it take until the cardboard on the parking spot will need to be replaced? Remember, even a few drops of oil is going cause lot of surface area on the car to get oily.

So, rather than trying to re-torque the bolts, you are going to buy brand new bolts anyway and have your friend spend hundreds of dollars so that you can fix his oil leak? Explain that logic to me please!

I already tried to talk him out of resealing the oil pan, but that idea didn't quite work. For the record, the oil pan gasket and aluminum bolt set totaled less than $50 from the dealer.

Re-torquing the bolts sound like a great idea...not. I have a feeling that these one-time use aluminum bolts (that require angle-torque) are not going to be friendly to any further tightening.

Clearly, you fail to grasp the concept of only doing proper repairs when working on another person's car. I'd rather make him pay for a proper repair than to put myself in a situation where I have to fix a big mess (that I caused) because I tried to save him a few bucks.

If someone's going to have me work on their car, it's getting fixed the correct way by-the-book (and they're going to pay for it) or they can go find someone else.

Critic, don't even think of retorquing those bolts, they are TTY.
With many TTY bolts you can get away with it, MB even gave a measurement for some TTY head bolts but these are a real one time only bolt and fragile ones at that.

Before getting into this look at the oil pressure sending unit. I don't know about the 08 but the older ones were on the back of the head and were a common leak.
If its wet, change it and clean everything off and see what happens.

You are going to put the new bolts anyway, so what is the worst that can happen if you re-torque them as it is?

I mean if you are going to install a brand new part, there is nothing wrong in trying to see if you can fix the old part. There is no downside to that approach. If the old part could not be fixed or it gets broken even worse, so what? You were going to replace it anyway!

That is the part I am not getting it.

Why is Trav suggesting he check the oil pressure sending unit? TheCritic has already made the diagnosis that the car needs new oil pan gasket. Don't you trust his diagnostic ability?

The bolts are aluminum and already stretched and have a sealant/ceramic anti seize compound on them from the factory. Do i really need to explain why you don't want to retorque them?

Pan gaskets are common enough but some of the inline 6 engines had a OPS that is hidden from view and only leak when the engine is running
If you don't know its there it can look like its coming down the rear of the block almost like a rear seal leak.
You know this already you Googled it so whats the point here?

The guy is doing his best to do the job and some people want to help him if i can in some way. Whats the problem?

Maybe The Critic was unaware of the possibility that the oil pressure sender is located there. All he has to do is stick his hand back there and feel for it and if it's wet. It would be a shame to mess with the oil pan if there's nothing wrong with it, or do a RMS. It's easy enough to rule out the oil pressure sender. JMO

Heaven forbid anyone take any good advice. Like Trav is some sort of dummy? He's only trying to help save money and time because he knows some tendencies. Platform specific knowledge is golden, especially on a make like BMW.

Please do explain to me why can't he re-torque them before taking the stretched one-time-use-only bolt off? What if they had come lose? Heck, he is going to throw them anyway, so why not try to see if they were loose to being with? Once again, I am not understanding the downside or you are saying that if they are loose, they can not be re-tightened. Or you saying that if he re-tightens those bolts, his oil pan is going to fall off on the road? I can't imagine it making the leak catastrophically worse. Or they have to be replaced along with the gasket right then and there rather than seeing if the leak becomes less after re-tightening them again. I am rational person, so explain to me logically why the approach I suggested is fatal. He tries it, the leak stays the same or gets worse or gets better. In first two cases, he is no worse off and starts his repair process.

The point was before going after the most expensive solution, rule out the cheaper ones. Now if replacing the oil pan gasket was trivial, then it would make perfect sense to just go for it.

He *must* have already ruled out everything else before deciding to embark on this repair. Wouldn't it be extremely bone-headed move to replace the oil pan gasket after going through all the trouble if the oil leak is from somewhere else rather than the oil pan? He won't ever be able to show up his face here :-)

Trav suggested it very gently to him but I am just a being little rude (we are all friends here, so little bit of ribbing should be excused!) about the entire approach taken by him.

If you try to retorque these aluminum bolts that are in an aluminum block for all this time/miles there is a very good chance they will break off in the block.
Then if he doesn't do the job he needs to get that out or it will have a larger leak, you do not invite this sort of fiasco.

You cannot retorque an already stretched TTL (Torque To Yield) aluminum bolt, some metal ones you can away with, its not the right thing to do but you can, aluminum is another story.
The only reason a TTY bolt comes loose is if the threads let go eg N* head bolts but that is not the case on this engine.

Come on now. You never missed something? I miss stuff stuff from time to time that might be hidden under some panel or behind a splash shied. I am not infallible, the last human that was died more than 2000 years ago.
Missing this sensor if it does in fact reside on the rear of the head on this engine would not be hard to miss for anyone not familiar with it. No shame there.

Please leave this man alone, if you cant help him then let someone who can or wants to give it a shot. Isn't that the point of this board or have we come to the point we just ridicule posters for asking questions?

Aluminum one-time use bolts is about the dumbest thing I ever heard of. I thought the Germans were smarter than that.

Along with the OPS Trav suggests, I would also look closely at the oil filter base gasket.....many have thought they had a pan leak only to discover it was the base gasket.

And, only a tool would try to re-torque a one-time-use aluminum TTY bolt. Doing so will cause a lot of uncomfortable, timely work.

I am way out of my depth here, but could he use non aluminium reusable bolts, replace them one at a time (so he doesn't have to remove the entire oil pan), and then see if the leak stops.

If it doesn't, then do the fuller repair.

Sure if in the unlikely event for some reason one had come loose, just use a low torque value like 10Nm.
For some reason they feel it needs a TTY bolt, being a small diameter bolt going into aluminum maybe they feel this isn't possible with a steel bolt. Just a guess.

I suspect someone has just used regular 8.8 flange bolts with a bit of blue loctite and torqued them to 12 Nm and had no problem. Its not spec so i wouldn't recommend it on a customer car.

As has been noted the installation torque is very low. I have found loose oil pan bolts on one of my BMW's.

I guess it's possible for a RWD car to have a subframe; I was just under the impression that only FWD cars have a subframe. By the way, some manufacturers use the term "Engine Cradle."

Have you verified that it is actually the pan gasket? The oil filter housing gasket can make a huge mess. That said, the pan gasket is starting the seep on my son's 165k mile 2004 X3 2.5- talk about a PITA job...

All the 79+ Mustangs have front subframes, usually referred to as K members. It is what you pretty much have to have with a unibody RWD platform.

Yesterday, the car was in my possession to replace the thrust-arm/tension strut assemblies and to perform a vehicle check. So, I took the opportunity to take some pictures of the leak in question:

Drops of oil around some of the oil pan screws:

Major splatter, or drain plug leak? Probably both:

It doesn't look that terrible. I'd wipe it down, replace the drain plug crush washer since that looks like its leaking and watch it. You could try to throw a wrench on the pan bolts and see if they will tighten a bit.

You must be new to this topic! Both these suggestions were shot down previously.

Have you inspected the oil filter housing gasket yet? That often leaks, and when it does, it makes the whole bottom of the engine look messy, making one think it's the oil pan gasket.

Well, from reading everything so far, that is exactly he plans to do.

If it were my old BMW I just wanted another couple of years out of, I'd fix the leaking oil pan drain plug for starters with probably a $.60 cent crush washer.

Than I would try to tighten the pan bolts.

After that I would just put cardboard down than trade it on, it looks to be a fairly minor leak. How much make up oil is added? If its less than a quart per 3k ignore it.

Trust me guys, I'm not that excited about this job. I'd rather go do a few suspension overhauls than an oil pan reseal on this beast. I already explained to the owner that he should just leave it alone, but he wants it fixed.

With that said, it does appear that the oil drain plug is part of the problem, but there's also oil coming from each of the oil pan bolt holes. He recently had the oil filter housing and valve cover resealed, but I will re-check those areas.

You also did not mention that the car does have high mileage for its age. It is just common sense to rule out simple causes and simple fixes before jumping on a huge task.

Knowing how methodical you normally are, why was the underside and the engine not thoroughly cleaned to find the actual source of the oil leak before doing anything else? How come you started asking the question about the oil pan replacement right off the bat? Yes, I did give you hard time on it but it was not completely unwarranted.

I've posted plenty of threads about this car, and the mileage was listed in the other threads.

I have already looked at this car twice and I am very certain that the leak is from the oil pan.

What is leading you to believe that my diagnosis is wrong?

I haven't fixed it - and do not plan to.
