240d

[harrygrey382]

Hi,
I'm new to these forums and am not yet (but hopefully about to be) a mercedes owner. I'm looking at a 1975 W115 240d. It is solid apart from running very badly. Story described is a mate bought the car, blew the head gasket, took it to another mate. After six months he replaced the gasket but forgot where the timing marks were.

He "ended up replacing the head about two years later..... put together another 6 months later, but by this time, forgot where all timing marks, chain etc went. So assembled as he thought. It runs, and engine sounds mechanically quiet and sweet but retarded sounding, with little to no power.... I think the timing is out.......on the cam chain."

Apart from possible damage caused by driving it with a blown gasket, is there anything major else it could be (or could this be a product of major overheating)? I plan on doing this work, and I assume the engine can stay in vehicle? Does it sound like a time and money wasting pit-fall I'm going for even if I totally trust what this guy says?

Its faily easy to re time the engine or check the timing, in the first instance it can be checked with the rocker cover off. its not easy to turn the engine under compression, so the injectors will have to be removed. turn the engine over by the nut on the end of the crankshaft damper pulley clockwise unit the TDC mark on the pulley is inline with the pointer,if you over shoot you must wind back a quarter of a turn and then wind it forward again clockwise. the timing marks on the camshafts should be in line, if not you can take off the camshaft sprockets and move the chain forward or back one notch as needed. that's all there is to it

Yep that all sounds fine. But does this problem sound like a timing one? Or is the description too vague to tell? I am looking at it before I buy but not for a couple of days.

Is this the 240 on Ebay??

 

[robparker]

yea i saw that on ebay too. not many 115 240ds about

 

[harrygrey382]

yeah it is. Opinions?

I would be vary surprised if bit started at all if the valves were not correctly timed. As far as I recall the timing marks are pretty obvious. Anyway if you can stand it I have a 200D refurbished engine in the garage that came from a 114 plus a whole rack of bits.

Well I ended up buying it. Haven't had time to get round to timing, hopefully starting this weekend though.
My Uncle's got an old 1967 200d, very nice motor, smoothe and high reving. I assume it's the same block? How much are you asking Tim?

Any sensible offer will not be refused. I will have to check but I think it comes complete with starter motor, alternator, gearbox and a load of 114/5 spares.

The engine was fully overhauled some years ago but in terms of mileage very few. It had new bores and pistons and big end bearings fitted.

Congrats on your new motor! I was looking at it on that there ebay, but it is a bit too far away from me.

I'm very keen on a w115 diesel, considering looking for a petrol one with good bodywork and doing an engine swap.
Would a 3 litre om617 engine (from a w123) fit easily? Am I right in saying that these (om615/6/7) engines were carried over from the w115s? If so I assume the 617 was used in the 240D 3.0 (why not 300D?!)?

Good luck with it, let us know how you get on.

Hibbo,
I'm not a Mercedes expert (yet...) but from what I've heard I'm pretty sure the 240d from the 123 is a straight swap. In fact I've been offered a complete 240d + gearbox which I'm going for as it's a good deal and it can't hurt having a spare.
I'll give an update on how it's going. Can't wait to get it on the road, it's a stunner!

An OM617 from a W123 will fit but the oil filter housing will occupy the same space as the steering gearbox. It will have to be relocated or replaced with an aftermarket oil filter assembly. DO NOT OMIT THE OIL COOLER.

Notice the oil filter was moved down by the vacuum pump in this car.
