aye, if he was nearer i'd have a gander! it seems to loose revs very quickly, when he was blipping it, that to me says its thrown something bottom end wise, causing alot of resistance.
Ive got a mechanic coming to look at it 2morro...the Oil light has always been working its just never actaully lite up.....When and if there was a problem..
The noise is just coming from the top just under the rocker cover...Its also ways Rev'd down like that even my Ibiza did the same..
Bottom end wise what you thinking ''Rod knock'' ?>

that is not bottom end related at all, big end shells and journals growl and squeak when spun or worn,
What oil are you actually using? 0-30 5-w30 or 10w40?
im between either a cam follower/ lifter or a noisey injector
its too metallic for small end rattle too, which you'll only really notice on acceleration, Big end failure you'll hear more on decelleration, so id count those out,
it does sound possibly like one cylinder isnt firing but its not lumpy enough to be this unless the rings have stuck causing slight piston slap. the oil breather hose that runs to the tip, might be worth disconnecting it from the tip to see if its kicked much oil into the tip, usually stuck ring/lack of compression on one cylinder will create heavy breathing/crankcase pressure due to the comprssion bypassing the rings to the crankcase, forcing the oil in the sump up to the tip/airbox one sure way to tell,
if its running on all 4 cylinders i very much doubt its anything overly major,
thats a big end failure, far deeper note, and non metallic

Im using 5w 30 castrol mate atm but i was using 10w40 carlube R before hand...It was misfiring before it done it..but i was getiing coilpack codes...
Im gonna put another litre of oil in it 2morro and see how it is then its defo sounding like its coming from under the rocker cover but theres no use listening to it under the car as everything just echos and sounds like its coming from the sumpp...but is alot more clear when you put ur ear on to the rocker cover..
whilst the engines running use a long screwdriver to your ear and touch it to different parts of the engine, crank case, cylinders, rockercover, use it as a stephascope it'll be most vocal where you find its from
Personally dont overly worry about it, worst thing you can do is think its this think its that, 9 times out of 10 its something simple
yeah stick with the 5-30 its less viscous at low temps than 10-40, people think that thicker oil cures noisey lifters which its the opposite to be honest, thinner oil is far better feeding hydraulic lifters from cold,
keep us updated, have you actually replaced the coilpack?

yeah il do that 2morro with a few other checks that you mentioned along with a compression test...
Ive replaced the coilpack but i can;t remeber if it was showing 2 or 3 cylinder..
also i never changed the oil pump as i was told not too....is there anyway to check for oil pressure?

id change the other coilpack either 2 or 3 whichever the other was for the one you took out,
these engines do seem to chatter/ tap when a coilpack fails, but im not sure if you've already tried that,
well i only got this tapping sound when it backed fired and misfired too...only seconds afterwards when i booted it...
i changed the coilpack but wasnt too sure which one it was as it only missed when i come to hold boost but was fine pottering around.

well id have a play with the coilpacks tomorrow, other thing is make sure the spark plugs are tight they can give the exact same sound if they're loose to be honest ive only just thought of that, ive only seen it happen on a bike but it does cause a knocking,
as for oil pressure, im sure the ecu would kick up a fuss if it wasnt finding a decent oil pressure, most cars detect a drop right away

well this was recorded on a phone, but it sounded like a lifter, it sounds alot deeper in the video that it was. it was purely coming from the centre of the head where i put it when it got really loud.

Then this was what had caused it.

So i wouldnt dismiss bottom end yet. big ends generally show on accel not deccel.its piston slap and little ends that rattle on deccel.
Ouch!!!
My Sounds nothing liker that though more of a ticking noise...got my mechanic coming today so il let you lot know..

im 100% certain that isnt big end rattle, personally ive never noticed a little end on decel and big ends ratting on accle, always the other way in my experience,
the vid of you posting the crown hitting the face of the head "isnt" piston slap which im sure youre aware, piston slap is a tolerance difference beteen the bore and the skirt of the piston, usually shorter skirted pistons suffer it more than taller, the oil cannot support the walls of the pistons against the walls of the cylinder causing the piston skirt to "slap" one side of the bore on ignition stroke, this is also caused by lack of oil and high engie wear , but usually you'll get other signs before this
piston slap, it usually clears once an engines hot it on a rover k-series which was known for it,

its hopefully something simple!

I had a very similar issue few months back - that annoying engine tapping on idle, but not as loud as in your vid
Changed the oil+filter and the problem disappeared so I was happy and never gave it much thought...
If you have a highly tuned engine I'd use a high-end 5W-40 oil but that's besides the point now.
Did the full oil change reduce the noise in any way?

Wow, different experiences then! every big end failure ive known has shon on accel lol. different experiences i guess!
Ah yes the good old k-series. mother freelander is slapping away like a goodun. lol. i do hope its something simple! it may even be something like a cam journel worn, meaning the cam is moving around when starting the lift of the cam.
ACTUALLY!!!!!!!!
Just had a spur of the moment thought!!
My mates ibiza rattled like feck, its an abf, but same cam basics. the cam sprocket at the end had the usual wear on it meaning it was moving about 14 degrees from memory, it sounded awful, like a diesel almost, but at 3k it went silent, making it seem like it was an oil pressure/supply issue. Just something that m,ay have happened.

Well funny enought you should mention this...
Both Ibizalex and my Mechanic has said the same think..Saying its something todo with the cam side of thinks Either the sprocket or tensioner...my rocker is covering off 2morro to see whats what as were on a lads night out 2night...
The Noise is coming from cylinder 1 & 2 area (Timing Belt Side)....Well from the sounds of a Sethascope but what side is the cam tensioner on?
cars Being stripped down 2morro to see what it is...he said it defo aint my bottom end But he will investigate more once its stripped down...

the chain side of the cam drive is passenger side, cambelt side theres nothing barring followers and a poss injector that could cause that noise, the cambelt side (drivers) has a jockey wheel and a tensioner, which would make a totally different nise to that, have you tried a the steph on the inlet manifold?
sounds can resonate round an engine which once youve got the rocker cover off you might notice its from somewhere totally different,

paul-murphys
efr 6758 here i come
He said the same think tbh..
Said with the noise being under a cover it can echo and be somewere totally different...We shall find out more 2morro
Hope it aint expensive...
