just got an email from my SA. here is the text:
I have ordered lifters for the complete exhaust side of the engine (of which lifters for cylinders 1 and 2 were replaced last time and will be redone).
We are also replacing the exhaust camshaft and rockers.
There is no noise from the inlet side, and hence we will not be disturbing that side. ]
has anyone else had their camshaft replaced?
