hello, bin Winne from Berlin and new here. I recently stumbled over an omi with gas system, price was ok, so bought. That started my problems. as the first head seal def, had hoped it was the cooler, no really the ZKD. (the seller also awoke) So let’s get started and head down (I learned this once 20 years ago, but something from the practice). Again and again amazing how manufacturers could build cars. I also rechashiert here before, Kurt from berlin is here really the hero, has helped a lot his answers. Somehow, however, someone else must have tinkered about it (if he is also here, many thanks) hoses loose, screws screwed in where they certainly don’t belong, etc. The head seal is somehow broken apart, funny. AGR probably stuck off, looks funny. My questions would be first of all: Why does someone screw a screw in the vacuum container, makes sense? AGR lack some connections, where do they come in? Head seal, ori ginal or accessories? Head is down, something is going to change, except now tarpaulins, valve shaft seals etc, that’s clear. I think I’m going to bother you more with questions soon mfg
