Hmmm

Strange the equivalent 15# drop.

Almost enough to start checking things.

I have the compression checked regularly, when I change the spark plugs. (every 20k km)
The drop from cylinder 2 to 3 was always around 0.4bar(~12psi).
The decrease over the last three years was about 0.2bar (6psi) in average. Ok, I guess. :cool:

But I thought it is "common" with LNF-engines to drop on cylinders 3&4...

I always thought 1&2 were commonly the issue.

Others??

Hmm.
I guess, the "rear cylinders" have to withstand more heat, caused by the engines position in the bay and thereby in the air flow...

Anyways, a buddy suggested to check the timing chains, as the ones on his GT emmitted comparable noises when they were stretched...
The shop will check them this weekend...

Number #1 cylinder is the farthest one, it fails most often when is about fuel starvation.
In my case #2 and #3 failed but because of high revving, oiling aspects generated possibly by track driving.

Guess what:
The Vibration is gone.

Obviously, the vibration came from a damaged Timing chain tensioner.
I had both chains plus accessories including all belts and the water pump renewed at a local Opel Garage and the Vibration is gone. Entirely.
The brace is now equipped with two Aluminium plates on the downfacing bracket, 3mm each, and will be re-installed this Weekend. Hopefully, this will not cause any new Problems. :cool:

Aye!

The cool thing is, it was the brace that made me check the entire engine an check every single sound... Otherwise I would possibly not have noticed the damaged tensioner which, following the shop, would have failed completely in short time... :barf:
