Knocking Noise On Lister LPW 3 Cylinder
Hello all, thought I'd try my luck in here to see if anyone had any ideas of what could be causing this knocking sound from our Lister LPW 3 Engine.
The noises started randomly one day about a month ago. It only happens in a specific low rev range and can occur in and out of gear. From what I can tell it's definitely coming from the engine and not the propshaft or gearbox. Have also eliminated the possibility of it being a random object in the bay rattling around.
The sound is best heard outside of the engine bay as per the video but I'll try put another video in the comments of the noise with the engine bay boards up.
Thanks in advance.
