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?
