Spark Plug Pipes M96.20

[thejack]

Hi Gents,

after a spark plugs replacement, the engine started to misfiring at low rpm and CEL went on.

When I visually inspected coils I found the spark plug's housing on cylinder 1 & 4 filled of oil.

Endoscope check found cracks on the plastic pipes that seal the valve cover with the cylinder head by the means of two o-rings.

I went to dealer and bought two new pipes, o-rings and two new coil ends that have been "fried" in oil and got crispy..

But my challeng is now to get the pipes out of their housing. I tried to use some home made extraction tool but didn't work out. Some of you have ideas about how to get that .... out of there? I have the car on the jacks and don't have any will to get it to the dealer and spend a fortune to have it repaired. Car is a 986 2.5 1997. Hint and tips?
