Spark plugs on CLK320 - What a b££tard

[wu56Shoozz]

Forget the above just saw the video and its nothing like I though...:-(

Also the connectors that plug into the coil packs get brittle and the locking clip snaps very easily.
The things with the orange bands at the top of the video above.
Handle with care but on the plus side new ones are available from MB.

Actually remembering back now - I think Star in reading said it would be £90 in labour to change the plugs which is not a bad business to be in for 23 minutes work
I'm think I'm going to try the garage here - I sent them the video of the cap puller and also of the bendy rod to measure auto box levels.

Hope my air con isn't too shot it's been without gas for 18 months+ and is absolutely hissing out.

Does my record still stand in a CLK430? 23 minuites.

I remember that day well, I think many were sure it was impossible

Its a lot more than 23mins work. As above, Olly managed this but he was prepared to do a timed change and I am sure he could not have kept that pace all day.

I have to do the plugs on my M271 soon so I hope it's a lot easier on the 4 cylinder engines.

I like the plugs to be sat there looking at you. There isn't an engine in the world that's quicker to do a plug change on than my BMW flat twin. 60 secs tops for both plugs.

...from the sublime (the BMW) to the ridiculous - the Stratos replica I used to own. It was fine until some idiot (me) nailed a supercharger and charge cooler and water/meth injection literally on top of it. Plug change was a bit of a faff.

That said, I did once swap the cams while at a rolling road session. Didn't actually take all that much longer than just doing the plugs.

Oh you should try a Ford Titan 4.6 engine!
You take those out with an air gun!
If not, doing it the old fashioned way they break off in the head!

Take a gander at this:-

Now complain about MB plugs!

Make sure he has one of these or buy one and lend it to him!

Yes , that does look a pig of a job on that engine .

With my M102/3/4 engines , and others , it's generally an easy pull off with the fingers , sometimes wiggling the cap in a circular motion as I pull .

The most obvious thing , though , is the chap in the video pulled all the leads off at once - I always do them one at a time as I change each plug , and put the cap back on the new plug before proceeding to the next one . Perhaps obvious , but no possibility of inadvertently swapping two , or more , leads that way .

Yes , I used my air ratchet on a very low torque setting to release a stubborn glow plug on the E250D , after much soaking with Plus Gas and gentle toing and froing with a socket hadn't worked - the vibration loosened it in a couple of minutes - if it hadn't it was getting left in place !

Yes!
In fact I use the same method with "glows" using a small 1/4 drive Snap On impact gun. Having soaked them first and a hot engine they will often come out without protest.
If they break I have a tool by Muller Verzueg to extract them!
For me the best tool yet!

if it makes it any easier i used a pair of plumbers pipe pliers on my cl55 cos the handles are nice and long still took around an hour though the back two were a bit fiddly to get a grip on

Ive done it in 18 mins. I can do it fast because I've done the job hundreds of times.

That's what I thought - levered off using the inlet manifold. Luckily you have a bit more room in an R129. Only took an hour to do 16.

Did you remove the coil packs? Made it a lot easier for me though not familiar with a CLK layout.

I was certainly glad to read that there's more room in an R129, though mines only got 12 plugs I'm hoping it would take me less than five hours and keep my skin intact.
