Hello it's Matthew,the fellow with the wasp ute.
I have taken off the head and after a couple of attempts found a workshop that is prepared to repaired it.
The head has burnt out exhaust valves,and the workshop is having trouble finding what to use to replace these.
We are also trying to locate a valve regrinding kit [head gasket set].
We found one for the G161 but the holes did not match up and had 3 holes missing ,and the exhaust manifold gasket is different so we need one for the G150.
If anybody has ideas i would appreciate it.
Matthew
