Re: My BMW 530d requires an engine rebuild

A donor part is the way to go

Happy that even after one car's lifetime it can still be useful to other car as donor parts

Off topic : In India we need to see Garage/Yard sales. There are a lot of useful stuff that gets thrown out into the waste/scrapyard without being utilized properly. Remember that episode from HIMYM where Tim Gunn transplants buttons from Barney's suit into another. Lot of things at home, that we don't seem to value can help someone else out.

Need some tips.
Mine (F07, 5GT) is also due and get the chain noise during cold starts and for 15-20 mins in to the drive. The engine is at 1.05 lakh kms and have scheduled for a timing chain and it’s assembly change this month. Battery has gone weak and I’m changing that as well. The car will go to a trusted bhpian owned garage here in chennai. Hope I have no other problems.

Did you check on the condition of injectors. Are you changing them as well?

As for machining engine components at a local machine shop, I would think twice. Better to replace as they are by design replaceable items and not meant to be repaired. Don’t cut corners if you are intending to keep the car for long.

Re: My BMW 530d requires an engine rebuild

Hi firstly very sorry to hear that your car needs an engine rebuild. For new age cars and specially being a German luxury brand it can a mental, physical and financial dilemma.

Coming to your point about replacement of the timing chain at your FNG the moment they mentioned that they need to open up the engine that should have triggered some alarm bells and you should ve just taken your car back and taken an expert opinion from an authorised workshop. The best thing to do after confirmation of the same is to either be ready with the finances to do the engine job or sell the car off ASAP. I would do the latter with a BMW for sure. Also if the entire engine would need a rebuild I am pretty certain that BMW india would definitely provide a decent goodwill if done at the dealership.

The suspicion arises when your FNG has mentioned that the Crankshaft needs to be machined on the lathe. That seems tolerable since before the main and the connecting bearings are fitted the surfaces need to be evened out and the crankshaft balanced. But what raises my eyebrows is that he said it is CRACKED. I am sorry but a cracked crankshaft can never be used. To my knowledge it would need a replacement. It is the stongest part of the engine. The crank works under tremendous pressure and that’s what transfers all the power/torque of the turbo charged straight 6 to the flywheel.

If such is the extent of the work, that would mean replacement of main/ connecting bearings, may be even pistons/ rings if your mechanic has done a compression test and subsequently machining work on the engine block. It can go on and on and can be quite endless.

I would say take an expert opinion if the engine hasn’t been opened yet. In case you do wish to open it up please take a proper estimate and then weigh the options as the figures can be astronomical for oem bmw parts. As the others have said you could end up spending 40-50% of the value of the car which is ready with other components to fail considering the age of the vehicle.

I'm not sure about the injectors>as of now What I have been told is to change the Timing Belt, along with the Crankshaft/and connecting rod. And as well as cleaning the whole engine.

As your Car has done more than 1 lakh km I would advise you to change the timing change ASAP. Don't make the mistake I did. I waited a little longer to change the timing chain (my 530d has crossed 115000)
Don't take a chance as I did. See my situation, apart from the timing chain, there were other parts that had to be changed which got damaged. I Should have changed it when it crossed 1 lakh. If I did that time Only the timing chain would have to be replaced but now I'm left with damage on other parts.

But then I take this as a good lesson.

Guys, Where can I find a used 530d Engine. Just want to compare the cost of it to the charge of overhauling my 530d's Engine, As for my Engine, I have been told Majorly, Crankshaft/Connecting rod along with the timing chain is what needs to be repaired or changed
Though it's a known Garage I need to compare the cost of used 530d engines with the cost of overhauling my engine. I still haven't got the correct quote from them for these works.
Anyways What do you guys recommend? should I go ahead with engine works or try to source a used one from some total damaged 530d. (if available)

The cost of these repairs soon works out to 25 - 50% of the book value of the car. That's why we see so many of them abandoned & left to rot. In all probability, you are either the last or 2nd last owner this car will ever have.

I don't see these high-end German luxury cars having a life beyond 10 - 15 years (15 is really pushing it) in India. They are too complex & too expensive to fix as they age.

Evaluate your budget carefully, how long you plan to keep the car and if you can get a good used engine from a total loss car.

Moving your post to a new thread. Let this thread also serve as a warning to those (including me) who buy used luxury cars. Tread very carefully & know what you are getting into.
I had the knowledge that BMWs are quite reliable and an engine overhaul of 530D at 1 lakh km is really unfortunate.

Really GTO this scares me as I was dreaming of buying a 3-4 year old pre worshipped 3 after 2 years.

Will certainly need your guys' valuable inputs before I actually take the plunge.

+1 to that.

I fail to understand how a lathe can be used to repair a cracked crankshaft. Setting that aside for a moment, if the crankshaft is cracked & conrods are damaged then your engine should have already had catastrophic damage elsewhere. i.e. beyond repair, even with factory spec equipment. If you are really keen on retaining this car - then you are better off buying an entirely new engine (half or full) or importing a used engine from Europe (provided you have the right contacts).

Re: My BMW 530d requires an engine rebuild

Ive owned a 2014 530d MSport. However i did only about 40k kms on it & used it very sparingly. But i have owned other vehicles that Ive done 2 lakhs kms on.

Firstly i am surprised your service tech never told you how critical a timing chain issue is when it first cropped up. A bad timing chain or belt WILL absolutely grenade an engine if not dealt with immediately.

But, now, thats spilt milk under the bridge. My immediate concern in the budget he's given you. I don't believe this is even Close to what such a job would actually cost. Ive had a piston & Con-Rod replaced in a Skoda a decade ago & it cost about 1 lakh back then !

A bad con-rod surely means your piston is messed up too. This in-turn means the bore/ sleeve needs to worked on as well. And fixing a cracked crankshaft in a lathe is a big NO !

I love the M57, its one of the greatest diesels ever built but, please keep all emotions aside & junk the car or sell it to someone after making a full disclosure.

The only other option is to take to BMW & taking the risk of may be few tens of thousands to get a proper estimate. If you can afford it, fix it. I know this isn't a solution you wanted to hear, but it is what it is. I hope you learn from this & move on.

Re: My BMW 530d requires an engine rebuild

Hello

You can call up someone at Man and Machine Hyderabad and ask them for guidance. They're a garage in Hyderabad that really seem to know their stuff. They also put up pics of original replacement spares on their Instagram page (stuff that the Germans don't sell over the counter).

They may be able to help you here.

Re: My BMW 530d requires an engine rebuild

The timing chain being changed at a 100,000kms rises a red flag. In modern cars I believe the timing chain should last the life of the car or at least till 300000 kms isn`t it?

I think your post(s) and responses to it were moved to dedicated thread. I'll attempt to be a bit vocal in this response. Please indulge me.

Please understand your car's engine is totalled. A cracked crankshaft requires replacement NOT a round of machining on a lathe. It is physically damaged. You can machine away score and wear marks but a crack means the inherent strength of the component has been compromised. A big no-no for a high output engine.

And this very serious damage means there may be other parts like con-rods, main bearings, big and small end bearings, pistons, piston rings, among other components that would require inspection and possibly replacement. That's going to cost you a lot of money. Please evaluate this with the market price of your used car.

So, the latter is a better option IF you can get a replacement engine from totalled car. And trust me even that one could be problematic. Please do your homework because you are opening a Pandora's box here.

Have you contacted BMW for their suggestions and an estimate for repair? Or, I know this might sound preposterous, if you have the budget and are keen to retain this car for a while ask them to quote if possible (a BIG if) for a new replacement engine. It'll cost you big time but I believe it's the only way you can be sure the car will run the way it is supposed to run.

What would I do if I were in your place? I'd sell the car in an as-is-where-is condition after making a full disclosure.

Good luck, I really hope this works out well for you.

Re: My BMW 530d requires an engine rebuild

Have you visited the workshop atleast once and verified the claims the FNG is making on the damages? If not, then it is high time you visit the workshop and have a look at the 'crack' on the crankshaft. I feel the FNG is taking you on a royal ride. You need to get your hands a bit dirty here.

Any update with the repair proceedings?

I faced a similiar situation like you, when my monthly salary was some 26k.
I bought a used, very old 800 for 33k, enthusiasm made me spend around 10k for some interior works. Same day, left the vehicle for general service at a fng and found out that the chassis was cut.

I got disappointed, spent again on some weldings, tinkering and paid some 7k. Just when I thought, all is well, another episode of troubles started.

The tyres needed replacement due to uneven wear, even the steering used to turn left and right like driving in some old movie songs. Speed of rotation was proportional to the speed of vehicle.

Replaced tyres with some rebelted ones, did alignments and took it on a trip.

The ordeal did not end there, the vehicle gave phenomenonal fuel efficiency but suspensions made sounds on every pothole like bomb explosions. While returning, it was dark and drizzling, wipers were put but, road ahead wasn't visible due to high scratches on windshield.

I prayed for the safe reach of my family and drove at snail pace. Another hiccup started after an hour of driving, one headlight went off due to burnt wire, very soon, another headlight also gave up.

I couldn't see any garage nearby, but luckily spotted one and asked him to fix the headlight. He replied that it is done by their electrician and currently he is not available. I opened the bonnet and saw one old 90/100 relay kit's bulbholder slit and connected to stock wiring.

I disconnected the wire and bought some thick wire from the garage. I joined the bulbholder wire with that thick wire and connected directly to the battery. Now, I could get atleast one headlight on driver's side working and drove peeping outside from the driver window.

Sitting in car, peeping outside with rain drizzling and with single headlight, I reached my family home, safely. Next day morning, I put up the car for sale and gave it for 29k, after spending so much for it.

I was the only bread winner and my brother still studying, just imagine my plight, with so much unplanned expenditure.
I wish, no one should ever face such situation, where there is no known end for expenditure. Time has come a long way and now I don't even think twice about any car expenses.

If one is facing such situation, it is better to sell that and keep your mind calm instead of crying inside.

Re: My BMW 530d requires an engine rebuild

An engine swap in a vehicle like that, is it even possible I wonder. The number of modules what not that should work with each other is mind numbing or maybe they all just work as usual.

Mechanical defects in vehicles like this are taken up by certain specialists in every major city, however the sight of these cars with their guts all over the place for many months is disheartening. The repair comes with no 'guarantee' and the parts used as well can be non-OE. I have been to many such places and their work is at best good enough to dress up the car for a re-sale, wherein the next owner will eventually abandon it on the side of the road.

I don't trust any FNG with even my good old Mahindra , forget about a BMW.

Navnit Motors (BMW) in Bangalore does counter sales. You can ask them for the parts, albeit with at least 20+ days lead time. Do not try to rebuild the crankshaft. Might cost you a bomb for a new one but will be totally worth the money. Balaji from Navnit is the sales lad. He's on +91 99163 87130. You can call him for parts. He might mess up details so you have to deal with a LOT of patience. For example, I ask for F30 oil filter and he ends up showing me F10 air filter

But a very sweet chap. Just talk to him nicely and he'll be happy to help.

Not true at all. Manufacturers themselves recommend timing belt/chain be replaced at 1L KM.

It is possible with the same engine family and models.
