Loud knocking noise from my 2.0 litre twin spark
It's been a while since I've posted anything here as I have had trouble free motoring for two years now.
The other day I was driving on the expressway doing about 110kmh and the engine developed a loud noise.
At first I thought it was a loud Tappett noise but then it developed into a very loud knock.
It all seems to be coming from the top end and not the bottom end. The noise is always there but varies in intensity.
The engine starts and runs but I'm afraid to run it too long (in case something like a camshaft actually breaks, the knock is that loud) to be able to determine exactly where the noise is coming from.
I removed the coil pack and plugs and cranked the engine and there seems to be no interference as the engine cranks over without any noise.
Any advice or help would be much appreciated, before I start stripping the engine.
Thanking you in advance.
