Hi all,
It’s been a while so posting an update. Got my car towed to the indie specialist who unfortunately only got round to working on it today. All seemed to be going ok, replaced tensioner, guides and chain but when they started the engine it would cut out after a few seconds, like an immobiliser kicking in. After a few attempts it got running but they said they could hear a rattle - maybe the same as the one people have heard on here. Seems strange as they have changed everything.
Now they need to investigate further and maybe take the head off to check pistons and valves. Could that be making the rattle? Any ideas guys? I was so hoping it would be straight forward.
