Hello guys, there might be some news about cylinder block at the V6 TiD. I spoke today to a friend who works in a special foundry. I told him about the V6 TiD that the bushings are lowering and that they become unusable from about five hundredths of a mm. He meant no problem, about the value of the block itself must be ground. He is a specialist for castings and is a vehicle engineer, and said that a material error is very unlikely. hr is supposed to be a technology error the reason for the lowering sockets. Then I have read everything that stands in the WIS for the V6 TiD. There it is expressly pointed out that “the grinding of cylinder block and cylinder head is not permissible. Nevertheless, see there, there are three different cylinder head seals for the same engine. These differ only in the thickness(!!!) of the seals. There are those with 1,15 1,20 and 1,25 mm thickness. These must be according to „Height of the piston My guess is that the returned cylinder blocks are simply sanded, which temporarily solves the problem. The three different thickness ZK seals seemed to reinforce my theory. What do you think? Toni
