CLK 270CDI Injector Seal Replacement

[machineheadrock]

Good afternoon all,

Hope you are well. My new CLK every now and again (twice in one month) had to be cranked a fair bit to get started.

Once was the day after I bought it (I got scared), and once was this morning.

It does seem like a rarity but it will need a crank. Reading, this is likely a common and easy fix.

It looks like injector seals is that right? I am quite handy with a spanner, is this an easy thing for me to do? I have not worked on one of these engines before, but plenty of others.

Can anyone give me the correct Mercedes part numbers for the seals, and I believe someone was saying three clear fuel lines are common at the same time to replace, can I also have the part numbers for these if possible?

I dont want to buy the wrong ones, and will just get it done on a sunny Saturday or Sunday to make sure that the problem doesnt get any worse.

Thanks

Injector seals leaking is generally characterised by a chuffing noise and evidence of fuel leaking around the injector seat.. Search on here for "black death"

To replace the seal requires the injector seat to be re-cut, they can also be difficult to remove, be aware that you also need to replace the clamp bolt.. Possibly better left to a garage?

Check for air leaks in the fuel system before you start pulling other things apart though.

On the two occasions it has been difficult to start has the fuel level been low?

+1 for an air leak in the fuel system.

Thanks for coming back to me. Once the fuel was low, and once (today) I have 3/4 tank.

How can I check the fuel system for leaks, fairy liquid test?

Look for bubbles in the fuel lines, there are O rings that can perish on some models.

Are the o rings easy to replace?

Have you got a part number for me?

Thanks

Mine can be iffy if I park facing uphill, and it doesn't need to much of a slope.

There are 4 orings on the pipes going into the fuel pump at the front of the engine, these are renowned for perishing, the new ones are green as apposed to black and are much better, just call into any merc dealer and ask for 4 orings for the fuel pipes and they will know what you mean, only a couple of quid

Thank you, any instructions for fitting?

If it only happens when cold, could it be glow plugs?

If you read the listing and send the seller the requested information, they can confirm it for you

Alternatively, as stated before, go to MB with your VIN

Well said!

It is particularly irritating when someone has been given a great deal of good advice and twice in the same thread seems to be posting sarcastic responses because they do not get the answers as and when they want.

The eBay advert clearly states a part number and a price per unit. If it were me I would by now have called my local dealer, checked for compatibility and checked the price.

It seems some people want their hand held through every stage.

What's the point in a forum when no one has any tips or advice apart from "plug it into a star, it could be a million things", or "call your dealer"

Might as well not have bothered

Cheers though!
