3.0l elite, not ran it for a few weeks, started her up fine, after a minute or so it sounds like a machine gun going off. took aux belt off & its still there. deffo metal on metal sound. top end.
does this sound like pistons & valves having a conversation guys?. :(
-
dont think it would still be running if it was....
lifters?

mmm does sound in that department, i dont know whether to let it run & see if it goes quiet or not.
-
presume it has enough oil in (and its cleanish)?

I would take the cam cover off and check cam belt/tensioners. My old man phoned me and said his MV6 was making a tappety noise, turned out the tensioner was in melt down :o

Exhaust gasket leak can sound remarkably like this.
-
yeah i'd got with that too, exhaust manifold leak i would say
-
Normally an exhaust manifold leak starts off noisy and gets quieter not the other way around.

def not, this is somebody with a hammer in the top end banging away :-/

Sounds more like a sticky lifter :-? :-? :-?

Agreed, sounds like a loud ticking which is engine RPM dependant & gets quieter as the engine warms up eventually stopping completely

update paul, doesnt make any noises until it fires up, no noise when its wound over. this points to the lifters to me, what do you think.?

Could be. Does it sound as bad as the green one did when running?
-
is it one or both sides ?
if you let it run, does the tone of the noise change as the oil warms up ?
-
sounds like you have a blocked oil feed pipe jon is it on both sides ? :-/ :y

its a heavier noise than the green one was, darent leave it running long enough to hear which side.

yeh, will have a look tommoz, been too busy today, out with the daughter to great central railway to see santa ::)
-
A pint says it's the lifters :)
I'd drop the oil for some fresh, pop a new filter on, and let it run up to temperature.
2.6 seems the most prone, in my experience, for some reason!
-
i reckon a lifter too, will check cam timing in the morning & go from there i think. :y
-

yep, you & me right. i thought the valves where having a conversation with the pistons. like 5 teath out :o. suspect this may be terminal :'(
i will fit new belt & tensioners & give it a go but not holding much hope tbh. :(
