One more thing, I’ve got a little bit of coolant from my 188 (1.2, 60hp, BJ 1999, with climate) and I’ve got a little bit of coolant on the left side of the cylinder, the ZKD was completely wet, the thread of ZK screw 10 (on the right side, if you’re standing in front of it) was rusted. No oil in the coolant. I can’t see at best where the seal has a crack to coolant channels. Since the whole ZKD was wet, the water must have been pressed between seal and cylinder head or block. How can this happen? The screws were very tight, the inside not as tight as the 4 completely outside. I’ll look in daylight again how plan the head and block are. I have not worked the block 1h with grinder tiles (see pictures before/after) and I want to put on a completely revised cylinder head. (My old ZK is in his life at least. 3x hot and 2x from Fikat can’t and has not seen it again. I’s a little bit. I have a bit of chill.
