Loud ticking from engine, place your bets now....
Discussion
Well after many years of ownership the Chim has decided to give me a little surprise. Started ticking last week, quietly on tickover then noiser under load. It wasnt really loud so popped over to Topcats annd let Warren have a listen.
We both ummed and ahhed but as it wasnt really loud and it seemed to be coming from somewhere in the top the consensus was probably a failed manifold gasket so booked in for next Tuesday.
I thought I'd have a fiddle this afternoon , I was going to make sure all the plugs and manifold bolts were tight and give it the once over so I started it up to work out where exactly the noise is coming from.
Ran for about a minute with what is now a very loud ticking noise that sounds like its coming from deep in the V somewhere. Turned off and went back in to sulk.
My money is now on eithr a cam lobe or a rocker problem. If its a rocker what are the chances its taken out a cam lobe as well grrr.
Hoping its not a slipping liner (heard on the LR forum that the V8 can tick loudly if a liner has come astray).
Upside, if its the cam its a chance to change to a stealth or something similar.

t you've lost a rocker padStick your head in the engine bay while she's running - if it's from the bowels of the engine then maybe the cam, if the noise if nearer the top end then maybe rockers (obviously not scientific). My bet is on the cam as I know the noise sounds similar to mine in the way you describe it - I ended up with a Taraka upgrade from Power when they did mine. Never looked back!
I have a loud ticking and vibration from my fuel rail / injector pipework on top of the engine, I found this when trying to find the source of my engine speed related noise with my listening stick (large screwdriver) maybe this could be your noise. If I just hold the blade to the pipework there is a hell of a vibration and the ticking sound sounds like it's from inside the V.
I did clean the stepper motor but this made no difference

Really hoping it's the same story with mine. Stripped the offside manifold off last week (PITA) and bought new gaskets from TVR Power (nice people). While I was there I've 'treated' myself to a new set of manifold bolts too, nice n shiny. Hope to bolt it all up at the weekend and enjoy the V8 howl without the annoying ticking sound.
