Hi everyone,
​​​​​​Finally, the crankshaft issue happened to my car which is 2006 C230 6 spd manual. Now it didnt run any more, so I decided to change the engine but I want to find the engine whose number is higher than

• M272 Engine Serial No. 2729..30 468993

​​​​​​I want to find M272 engine, but there are many of them out there. So I have a question, can I take any M272 engine from such as SLK300 or E280 to put in my car? Since it is different type for these car, so I am not sure it is fit or not.
If you have any idea for better engine suggested with example is pretty good as well, please let me know. I live in Surrey, BC, Canada.

Thank you so much!
Have a nice day!

What exactly happened to the crankshaft?

My car has this m272 engine whose number is lower than Mercedes upgrade serial no. Since I drove too hard and now it has 175k km on it. Crankshaft is gone, and now the engine is completely gone.

I wonder that is it ok to use the C-class W204 engine for my C230 W203?
Thanks everyone!

You mean balance shaft not crankshaft, personally I would repair it, Then you know its all new inside, a 2nd hand engine comes with its own unknown issues. New balance shaft new chain and tensioner and rails. All sorted.

From the following listing on ebay, it looks like that engine is common for only 2006 and 2007 C230.

Oh, so can I fix the balance shafts themselves?
Since I didn't know my car had balance shafts issues, that was why I tried too hard to drive it, and then it stopped and couldn't start again. It just had "tick tick" sound while we tried to start it.
Before the engine stop running, we pushed the car to started as my car is a manual transmission. And now, the mechanic couldn't spin the engine by hand. Do you think I did harm the whole engine?

Thank you so much!

mckenny

Thank you for your research!
Since W204 type also use M272 engine, that's why I doubt it is suitable for mine or not because I don't want it to have another balance shaft issues again.
Do you have any information about that?

Thanks again!

mckenny

I've checked out the kind of M272 engine on wikipedia which is used on 2005- 2011 C230. Does it mean the engine on C230 year 2008 - 2011 which has W204 type suitable for my car?

Russell Ormerod

Well if the motor is now solid it probably broke a timing chain rail and bent all the intake valves. So yes its probably fixable at double the cost.
Strip the motor first, asses the damage before you buy second hand.
I have done a motor like this, with the same issue as yours, crank and pistons were still perfect. New rails, chain and a cyl head overhaul and its running sweet. And a new balance shaft of course

mckenny

Thank you for your information and I really hope I would have the same issue as yours.
I will ask a mechanic to strip the engine, but if the whole engine is gone, it was waste $ for the labor cost to examine it.
So I still need 2nd solution which is finding whether the w204 engine fit my w203 or not? Therefore, I can compare 2 cost for these choices and decide what to do.
Thanks again Russell!

Wish you a great holiday!

Russell Ormerod

The motor must come out anyway, Then just an extra hour or so to strip the front cover off, then you will know the extent of the damage. Any 272 will fit in your chassis. The engine mounts and brackets all bolt on so any slight difference will be a swop over

tjts1

Put a 3.5 in it. Same engine, same electronics, same everything except bore and stroke.

mckenny

Thank you for your idea. I will try after holiday.
Have a nice Christmas!

mckenny

Yo, happy to hear that! Thank you much!

mckenny

Hi everyone again,
I just figured out another question.
My car is manual transmission and RWD, so do I have to find the same engine has MT & RWD or I can use the AWD/AT one?
Thanks again!

tjts1

It has to be rwd, it doesn't have to be a manual.

mckenny

Thank you for your confirmation. I'll try my best to get my "honey" back.

tjts1

If the engine comes out of any other chassis, you will probably have to swap the oil pan. Your best bet for a matching oil pan is the w209 clk

mckenny

How about the W204?
So should I find W204 or W209 CLK engine? Please give me more info to widen my choices. Thank you, tjts1!

Russell Ormerod

Even if the sump differs you can use the sump from your old engine.

mckenny

Thank you all. Christmas is over, tmr I will check what I will do with my old engine. Thanks much!

mckenny

I've contacted to recyclers but they told that they had fit only 2006-2007 only. But after I check online, I found that the m272 is upgraded from 2006, that means 2007 when W204 debut, the engine is still the same as the old M272.

tjts1

Thats because they want to make the job easy for themselves by using an engine out of a w203 with the same oil pan. Late 07 w203s didn't have the intermediate shaft problem so that might work for you.
