After a high speed run on an airfield (154mph), a lifter noise suddenly began, we have isolated it to number 7 intake and replaced the lifter- the noise continues!
We ran the engine with the valve cover removed and you can quieten the lifter by tightening it until all is quiet....for about 3 seconds. Then the tap returns.
All the valvetrain seems ok, pushrods etc and we are pretty much foxed. Any ideas?
Thanks from a very wet England
