Engine rattle at 3k rpm

Previously my engine had a small rattle at about 3k rpm (or could have been 4k, it's been so long since i have driven it!). The rattle only lasted about 100 rpm.

I heard a ping and no more rattle, but one of the cylinders now has a knock! The turbo no longer charges up like it used to and there is little or no noise from the dump valve. Before the ping, the turbo would intermittantly dump slightly under acceleration, again, this no longer happens.

I have heard recently that the rocker arms are weak, but I am worried that it may be something a bit more major.

Does anyone have any ideas?

Seems oil was not making it to the cams and they are knackered, turbo actuator was not working either...

The engine is being re-built at the moment!

My car is with "the garage" in Wishaw. It's more of a skyline specialist but they have done lots of 14's and they seem to know their stuff ;-)

I should have the car back next week some time hopefully...

I had hoped to hold off for a full stage 1 rebuild from horesham next year but i guess thats put back little now.

Had an update on the car.

Re-build is cancelled. Top end noise was something to do with oil buckets (whatever they are) and the bottom end(ish) noises were the Dual Mass Flywheel dying.
