Hi all. I have a question & am seeking advice both for a solution & to get an idea if the guy I took my car to is "onthe up and up." A few days ago, my 1987 190E 2.3's engine started to shake severely. (is worst when in drive &/or idling) Other "symptons" also include a significant loss of power (barely makes it up steep hills) and sluggish acceleration in general. Thinking it might have to do with the spark plugs, I took it to the place where I had them changed a few months back. They inspected the plugs, discovering oil on one of them. He then told me that as a result, I was only running on only 3 cylinders and basically had 3 options; replace the engine, rebuild the engine, or he could do some kind of temporary fix he called "an extension" (for the cylinder that leaked oil onto the plug). Has anyone had any of these problems &/or have an opinion about the diagnosis I was given? Thanks in advance for any replies.

 

I am having the same problem with my 1995 E320. I also found oil on 2 of the spark plugs. Imay try a valve cover gasket replacement before I take it to my shop. I am not looking forward to facing a steep repair bill.

 

What did you end up doing to correct the problem(s)?

 

Do a compression test on each cylinder. If compression is good all cyl what type of plugs did they use?
The extension thing i believe is no more than a tube spark plug extender. Using them before
i can tell you they only last a few hours too much compression oil has to go somewhere.

 

ive had that same problem i just replaced the plugs and ran smooth and no shake
