Hi back on again looking for advise on how to get on top of a persistent water leak.
This problem has gone on for months now, it started after I had the Z in the garage to get the numerous small seals around the front chain drive covers replaced to cure a minor oil leak.
I was advised that whilst all these small covers were removed to get the chain, belt and water pump replaced, plus the head was removed and skimmed and valves and head gasket replaced.
This also involved removing the water connection at the rear of the head which I understand is just pushed but has a ring seal and held in place by 2 bolts on a flange.
I identified this as the possible source of the leak to the garage and to give them their due they replaced the pipe connection and applied a sealant around the connection to the head.
Unfortunately it continues to leak, has any one experienced this issue and how did you cure it, so that I can pass this on to the garage.
