BMW original remanufactured engine

[maicol76]

Currently, I am under the situation where I need to replace S65B40 on my E92 M3.
It is being replaced by local BMW dealer, and I saw there are two different engines on the parts catalogue.

One is short engine(new engine) and one is remanufactured engine.
What is the actual difference?

Is there someone who knows BMW remanufacturing process of E92 m3 engine and give me detailed information about difference between two engines, especially equiped parts, quality, material, durability and performance.

Ugh. Sorry to hear.

Short block - engine block, crank, pistons. No accessories.

Long block - block, heads, oil pump, oil pan, filter housing, maybe water pump. No accessories such as a/c compressor, steering pump, starter, headers, etc. IOW, a bare bones engine. Everything to make it fire and run needs to be bolted on.

Reman means its been disassembled and put back together to factory specs. Critical parts such as bearings are typically new. Major components if they meet factory tolerances are cleaned and reused.

Essentially a rebuilt engine.

I don't know if BMW rebuilds these motors themselves or farms them out to a competent sub contractor.

More recently, I bought calipers for my E36 M3 race car which were considered factory new, but upon closer inspection I could tell they were clean cores with fresh everything. I'm sure BMW didn't rebuild them or ATE for that matter but a qualified subcontractor. Important thing was that they felt new, installed new and worked like new, even on a race level shake down.

A rebuilt engine is as good as new, I wouldn't worry about it.

Just a thought, you are in CA. Why don't you give Dinan a call and see what they can do for you. If you are paying out of your own pocket for the rebuilt engine, then why not opt for a 4.6L stroker kit. If you are going through warranty, perhaps Dinan can talk to BMW (sicne they have fully licensed service facilities - I think) and maybe they can work out a deal for you. Dinan gives 2 year 50,000miles warranty on their stuff - I think.

What happened?

From my understanding BMW calls there long blocks "short engines" or so says bill pearce BMW in Reno NV's shop foreman

[Dave07997S]

Whoa guys, remember. There is a difference between re-manufactured vs. rebuilt. A reman engine is basically a new engine other than the head and blocks are used but are within factory tolerances.

Within the BMW catalog it is a re-manufactured engine or new not rebuilt.

Tiato got it right..a short block is just the block and all components, no engine dressing. While a long block includes the heads.

To the OP, the reman'd engine will be fine.

99.9% of the times they go for reman

Now, I live in Seoul, Korea.

My M3 suddenly started to have vibrations and ticking noises from the engine since 2012 spring.
Since it kept got worse, I have brought to the BMW service last month.
It seems like my engine suffers rare S65 engine main bearing failures from what I found on BMW forums.

They have opened the engine and found damaged main bearings, and made me wait long for BMW Korea’s decision.
After many weeks(6 weeks +) they finally have decided that my damaged engine is NOT covered by warranty.
Currently they are asking about USD$12,000 to replace the whole engine(short engine or RMFD engine).
Their excuses are that I have not used BMW oil filter, and I have not brought the car for oil change to dealer at 25,000km.

I have been changing the oil every 5,000km-6,000km with Castrol TWS using BMW filter for last 3 times. My last oil change(4th change) was done at 26,100km with Mahle filter on Aug of 2012. Current mileage was at 29,000km when I brought the car into the service due to engine vibrations.

Although I am very understanding person, this whole situation does not make common sense at all.
BMW Korea requested numerous documentation for proving oil changes and etc. I have provided all of requested documents, and also have got answers from Mahle group that their filters are exactly same as BMW filter.
BMW Korea still denying the warranty as of today. I believe there are many flaws I can fight back legally on BMW Korea’s statements.

Xking situation..

RMFD or new, Which is better?

OP, sorry to hear what happened. If bring a search results for all the engines here that failed. There are a good number.
Someone should start a Registry thread for everyone to keep track of these bearing problems. It'll only help the community in the long run.

But $12,000 US for a new engine is pretty good.

[Vic311]

It is important to remember that "remanufactured" in this case means BMW remanufactured, exactly to BMW specs and tolerances which is equivalent to new.

[VCMpower]

You certainly have a case I would assume, but you should consult a Korean lawyer. Mahle products are very good. Meet or exceed factory specs. We use Mahle largely at my shop and in 20+ years, never a problem. Mahle would be interested in hearing what BMW Korea has to say about their product I am sure! Using the correct oil and doing such frequent oil services does not support what BMW Korea is saying to you. The obvious question by looking at your pics is why only 1 journal? A inadequate oil filter or lack of oil changes would show signs more consistent through the motor. Fight!

Crazy question but if "remanufactured" in this case means BMW remanufactured, exactly to BMW specs and tolerances which is equivalent to new, but the original motor only lasted 29,000 km, is that really a good thing?

But it was the oil filter! :

How much would a rebuild cost out of your own pocket

[maicol76]

Thanks for reply, guys.

The total cost of reinstalling engine is about $39000(short engine) or 33000(rmfd engine).

But, I should pay 30%, not 100%.

so,
short engine(new) => $13000
reman engine => $11000

So they are splitting it with you? 70% them, 30% you. While they should pay 100%, at least they aren't totally denying the claim.

[StealYourFace]

Where in the hell do they come up with the price for these damn motors. God thats insane you could buy a decent used m3 for 39k. I'm glad you didn't get stuck with the whole thing but even 1/3 is nuts.

BMW reman parts are usually new. They label them as reman and require core charges for tax reasons (reman parts require less duty than new parts)
