Should I remove the pre-chambers?

[Dudernio]

I'm pulling the head off my OM603 1987 300SDL with the #14 head. I suspect either a cracked head or blown gasket. Is there any reason to pull the pre-chambers? Will anything be revealed by doing so? And if so, is it wise to pull them while the head is still attached to the block?

It has been consuming coolant steadily over the last year, I would fill the resevoir about every 500 miles. The top radiator hose always pressurized after the engine cooled the next morning. Finally one day after a long drive, when I went to restart the engine it would not turn over due to hydro lock.
