Hi all,

Two quick, I think, 1995 e320 questions.

1 - Is the low pressure ac port the one that is very easily accessible and near the manifold. The smaller one?

2 - Any famous last words from anyone who, like me, has been driven crazy enough by a top end tick that they opened up the valve cover and replaced the offending lifter? I have done a head gasket so I have been in there before but did not pay much attention to the lifters. Can I find the culprit by pressing down on each one and seeing/feeling which one is different? Or do I have to run the engine and watch the valves?
I saw a video on YouTube where the guy just pressed on the lifters without the car running and it was obvious which lifter needed to be replaced.

Thanks very much,
Jim Lee

 

Hi again,

I have the valve cover off and am staring at the cams and lifters. I would rather not replace all lifters. Do I just remove the torx bolts that hold the cams down and remove the cams then press down on the lifters to see which one is bad? Or do I have to actually run the engine first to find out what lifter is not lifting?

Also, is there any diy doc about removing the rocker arms on this engine?

I have the Technibooks "Mercedes W124 1985-1995" Owners Workshop manual and it has nothing about removing the cams/rocker arms.

Thanks very much,
Jim Lee

 

usually the valve guides go bad on those motors. and they do sound like lifters.

low side is small and high side is larger.
