FOR SALE Reconditioned 500E (5.0) engine for sale

[Rouven036]

I am selling my original 500E 119.974 engine, serial number in the 37xx range. Euro Version with oil cooler connections, with double valve springs and metal cam oiler tubes. Timing cover has the mounting stud for later style spring tensioner already.
The engine has run prior reconditioning around 240000 kilometers.
I have reconditioned the engine to increase power output, was also prior rework in proper condition.

Only original Mercedes-Benz parts have been used:
8x 0.5mm oversized pistons
Crank and connecting rod bearings
Timing chain with all guides
Oil pump chain with new tensioner and spring
New valve guides and seals
0.1mm resurfaced heads
Polished intake and exhaust ports
Vacuum and idle air hoses
All gaskets and seals replaced
32x Lightened valve tappets from later single valve spring version
ECU with top speed limiter removed

Crankshaft was checked and journals polished only.
All bearings in standard diameters, bearing clearance set as per available 3 tolerance sizes for standard diameter.

Engine was driven since reconditioning approx 3500-4000km only and has been only replaced due to installation of an original 6L AMG variant.
The engine performs very well as it pushes the fully loaded (4 person's including luggage) car with 18" /245 tires all around and 2.65 diff to the rev limiter.

Engine comes WITHOUT:
- injectors
- throttle actuator
- wiring harness
- distributors and rotors
- ac compressor
- tandem pump
- ignition leads
- air injection pump
- alternator
- exhaust manifolds

Hey guys just want to give you a short intro on myself, have been a member on the old ecstsy board but was not a very active user. i m from germany but working and living in the middle east since a few years. own my e since the year 2000. bought the car from the first owner, but that guy is/was...

Just a question regarding the lighter valve tappet upgrade for single valve springs, while you also say it has double valve springs?

.

 

[Rouven036]

Yes, early engines have double valve springs due to heavier tappets. So the base engine is double valve springs and I installed the lighter tappets of the later engine which are 18gr each lighter.


Did the same on my 6L only retrofitted there the double valve springs as it was a single/konical spring motor.

Is there any advantage to the dual-spring setup? I thought the single-spring was preferred.

Genuine question, is an engine albeit rebuilt including some upgrades with ~150K miles worth €8500?

My understanding is the engine had 240kkm (149kmi) prior to the rebuild, and only 4,000km (2,500 miles) after the rebuild + upgrades.

Where are you going to get the genuine parts needed to repair an engine to this level? The fact that it is next door to impossible now to get parts for such an undertaking fully justifies the price point. At least to my mind this is a great offer

 

[Rouven036]

As written in the engine has currently a mileage of 3500-4000km only and had prior to the full reconditioning about 240k km.
The overall price is fair imho as a rebuilt with all related machining work will cost you more and as also some parts such as original oversized pistons are NLA meanwhile.

Doing this all at an reputable engine builder should net you at least 3 times the price.

 

[Rouven036]

Is there any advantage to the dual-spring setup? I thought the single-spring was preferred.

The double valve spring setup is better as it is more rpm stable when paired with the lighter lifter. A broken valve spring also is less likely to kill the engine. Some of the conical spring on various mb engines have been reported to failed/broken.

@Rouven036,
Just a question to clarify in my mind albeit I won’t be purchasing the engine.

With the 8x 0.5 mm oversized pistons did you have to redo the nakasil cylinder walls?

 

[Rouven036]

Hi Terry, yes indeed, the specific bore treatment was performed using the acidic paste to remove the aluminum and maintain the Silicium crystals only.
The cylinders weren't worn actually but after dismantling and cleaning the old pistons I found the ring play, especially on the oil ring on the borderline of acceptable. Also I didn't want just to put on new pistons in run cylinders so opted as per the manual for the first repair size which is also a very mild capacity enlargement.

What Shop does touch in those days m119 and nakasil Alusil cylinders for oversized rebuild?

 

[Rouven036]

It's technically not that challenging given the normal honing machine equipment and required stone sets and felt blocks with etching paste are on hand.
I have got this done for this engine through ATEC Motorenbau, nowadays you still can do the job at several engine builders.

I have even purchased the material and performed it with a local machine shop in Kuwait for a M117 6L built...

 

[bb1]

All I talked too, they don’t touch m119, specially if you want the crank rebuild too.. (new Oversized Pistons and Rods provided)
that was some years ago, will have to search again..

 

[Markus-MD]

Double Valve Springs are typ made for higer Revs.Konical Springs was made for more silence in the valvetrain and reduces the power to operationel engine.maybee reduce Fuel. M104 300 24 v Have double and go up too 7200 .The later ones with conical goes up to 6500.its a question of trust what is better.

How should I understand that? That its not true what I am writing or that the block has not received the Silicium treatment?
I hope not!

I guarantee that the work has been meticulously been performed as documented in the manufacturer manuals by atec back in the day.
On top I will get pictures of the cylinders in a couple days.

It may very well depend in what context you have dealt with those people and the extent of work.
Which will result in a rejection especially if parts are provided. Key word is here the gewährleistung. What make where the oversized pistons? I wouldn't take any responsibility as a engine builder if I should fit pistons which are not ferrocoated for example.

There are quite a number of people experienced with this and it is no rocket science. Bernard, mkb, f&s, atec (under new and younger owner since a few years), bjön Pieper BP Motorentechnik (he is building a 6L engine for a 124 at the moment as the car owner posts regularly updates on his Instagram page) etc.

Correct, fuel consumption is "reduced" as the spring rates can be reduced resulting in a reduced internal friction.
The damping effect is achieved by the conical shape however double spring dampening is superior. Lastly the lesser parts are just reducing manufacturing cost. Double valve springs for the win...

Completely misunderstood.. just saying all I talked to back then: „rebuilding the block, yeh, maybe, we would have to look first. Nooo we can’t do crank with new balancing etc.“ or want to do that.

Time changed and now some shops have new owners… and next question is, what they will charge for it.. if I compare my custom build marine racing engine with prices for a rebuild m119 block: all new 632cui, all the best parts, 5stage drysump, jesey parts, cnc heads etc. N/A and 1025Hp@ 6800rpm and then you pay more for a Standart m119 engine overhaul @ Bernhard. I don’t think so.. it’s still a m119, nothing special about it. MB v8 and not more, mass production engine.
I like the m119, don’t understand me wrong there.

Your deal is not bad at all, but for most is the not matching engine # a problem.

The Parts I got are all original MB NOS Parts.. no aftermarket at all!

 

[Rouven036]

That's fine then it can be easily misunderstood though...
I understand what you say about the reconditioning costs as I too was shocked when I built a big block for my formula 233 in the past of how "reasonable" everything is. Nevertheless is labor a large factor in cost nowadays.

The 119 Block overbore, honing and final Silicium lapping cost was exactly 800€. Reasonable overall.

For fine balancing the rotating assembly of the 6L I paid around 1100 or 1200€.

Also looking at my evo1 engine which is the first full build someone else does for me entirely due to the lack of time - the cost is substantial considering all the big parts were already supplied. Here also the biggest share goes into labor for designing, fabrication, testing/assembly. Something I am enjoy actually most but can't due to distance and lack of time back home.
