Good afternooon all....
I have a 81' 380SL convertible. About 10,000 miles ago the timing chain broke and had to get the valves and engine rebuilt. Got that done and this afternoon a rod, bearings or piston broke and alot of metal clanging noise is coming from the driver side of the engine...I am contemplating the following:
1. Selling car as is
2. Fixing car at auto shop
3. Pulling the engine out myself and getting it rebuilt
4. Pulling engine out myself and replacing with a rebuilt motor.
The problem is that i do not know approx how much any of these would cost.
The interior of the car is good...having issues with the A/C (needs amp and servo) to work, otherwise not sure how much to put the car up for sale as it...2,000 or more..what do you all think???

I'm sure the auto shop will cost approx 3000 to 4000 bucks, so anyone know the cost of a rebuilt motor for this vehicle and or how much i should sell the car for?

Thank you so much

Gary

Mercedes-Benz may have a re-built engine with a 90-day warranty with the dual cam already buit in. The cost would be in the range of $2,800-$2,900. Installation would be an additional $800-$900.
Get a quote from THE AMERICAN SERIVCE CENTER, Mercedes-Benz. If you want to do it yourself get a quote from POTOMAC GERMAN AUTO for a used engine. They are hard to find now. They may have one. $500-$800. Be sure it has the dual cam however.

Welcome to BenzWorld Gary! I'll slide your post down to the R107 section, where it's likely to garner a fair amount of attention.

Ouch, sorry to hear that. It's, uh... unusual that something would seriously break only 10K miles after a major engine rebuild. Assuming all the work was done properly, I mean.

I am contemplating the following:
1. Selling car as is
2. Fixing car at auto shop
3. Pulling the engine out myself and getting it rebuilt
4. Pulling engine out myself and replacing with a rebuilt motor.
The problem is that i do not know approx how much any of these would cost.
1. The car market in general, and for cars like these in particular, is in the toilet. You won't get much at all for the car if you sell it with serious engine issues. I wouldn't expect more than about $1000.

2. The cost would be something more than $100 and something less than $15,000. Without knowing what is making the noise, there's no way to be more specific than that.

3 & 4. These engines shouldn't be rebuilt by the average Billy Bob's Beer, Bait and Engine Repair Shop. Getting one rebuilt by an MB specialist usually costs around $8K - $10K. You can buy a short or long block rebuilt by someplace like Metric Motors for about the same amount. That's probably more than the car is worth, so you'd have to decide how much you love the car. I'm upside down in mine by quite a bit, but I love the car, so it doesn't matter to me. A professionally rebuilt engine would last a good, long time.

You don't mention 5 - pulling the engine and replacing with a known good engine from a car with serious rust or other body issues. That might cost you $2K-$3K, with you supplying the labor.

thank you to everyone....I am seriously contemplating on keeping it or not. I feel as if im already too deep into the car. Im about 10,000 into it right now thats with the price of the car and the last engine build...and i really didnt want to spend another 4,000 or so to get it back on the road...ugh i hate times like this. Good thing is this is not our only vehicle.

Start looking for a used engine. There are several used M-B parts retailers, and you may even find something locally. There are lots of rusty 107's that, as a vehicle are worthless, but contain a viable engine. You'll never get back the money you've put into it, but you'll increase it's value significantly as a running vehicle.

The good news is they did make enough of these cars that some are ending up at the junkyards. Unfortunately many of the 380s at the yards have a similar history of killing the engine. Start looking on craigslist, I see someone around me is parting a 380 engine. They are around and you won't be fighting off other buyers so keep your options open.

OUCH, Well welcome to the 107 AND goodbye, by the sounds of it.
My purchase was a similar one excepting the timing chain had already been replaced. Guy had to get it sold, I was the one that came up with the cash... Good luck on your move, maybe once you get settled in you could try to locate another one, maybe..:thumbsup:
