Gents - back for more help…
So, as you may have seen from earlier post, I have just had my oil sump off. Changed all the oils, replaced sump - no leaks; all good.
Touched nothing else.
Test drive and few minutes in this nasty noise appears.
Gingerly bring it home. Thought it came from under rocker cover so took that off and checked all tappets. All good and still at correct gaps. Timing still spot on.
Put back together. Noise still there. Horrid noise - have tried to get reasonable audio of it and embed it here (never tried that before - hope it works!)
Youtube vid (audio only):

First at idle then with revs. You’ll hear the noise rises with rpm.

Everything was running smooth and fine before oil change.
What could have happened? Where do I look next to fix it?
Why don’t I ever learn that when things are running right don’t touch anything?!?
Anyone got an ideas on where this noise is coming from and why??
Thanks.

just trying to get the audio file to play properly - works on my phone but not my computer. will fettle.
meantime - 20w50 oil used (same as i usually use), nothing left in sump - carefully checked all tools in and out (and bolts etc).
Hoping not to have to remove nicely sealed new sump gasket or re-drain 7 litres fresh oil! But i guess i could have moved the oil pick up somehow (does it move easily?). Will get back to you all when hopefully can share audio if not working already.. first the landy now the bloody internet...not my f&*ing day..
 
@Bobsticle @Hicap phill Audio now on Youtube (what a pain...be great to be able to upload audio files here as easily as pics!)...
Will also edit original post.
Be good to see what you think - does it confirm suspicion of oil pick up or anywhere else i can look before having to re do the whole sump?

As it’s a lower frequency than revs I would guess flattened cam lobe / tappet roller , it’s a head off job to check

That sounds like a lack of oil feed , but difficult to tell from a recording

Considering I just drained all the oil and replaced it, I’d prefer it to have something to do with the oil rather than a coincidental non-related fault. Though I can’t discount anything.
If it were a lack of oil feed, what’s the fix? Investigating that first would be preferable to taking the sump off again or removing the head (which I’ve never done). Cylinder pressures all as they were previously if that has any bearing. Nothing loose or striking engine anywhere.
 
Hell fire that’s nasty. One thing it ain’t is the bit of tin gauze on the end of your oil intake.
It’s big and it’s about to self destruct by the sound of it.
Me! I’d have the sump off and check the crank front to back. If all is well at least it’s just a sump gasket before moving to the top end.
If it is a crank journal at least you can do it from underneath with the engine in, as long as the crank is actually in one piece that is. :eek:
 
It sure is nasty! When I had the sump off I did take a good look round - mainly as i'd never seen the engine from that angle before! Took some pics - attached - and I had thought how good it was looking for a 40+ year old engine...all nice a clean and nothing nasty looking. No bits of metal in the sump, nothing seemed loose. Obviously now I'm kicking myself for doing it at all!

It's 'possible' I put the oil filter on wrong / badly - I've got the one that has the spring and cap thing that pushes the filter up inside the housing. Never f*cked it up fitting it before, but maybe I arsed it up this time and it's blocked or something...could it be as simple as that?? (he says hopefully...)
I'll take it off tomorrow anyway and check. If that looks fine I'll get the sump off again and prod about and see what i can see - that sort of noise would surely leave a mark somewhere on something??
If i see nothing there I guess i'll need to learn how to remove the head - not looking forward to tackling them bolts!

Out of interest, why did you remove the sump in the first place? It isn't part of the usual oil change procedure.

Also, if the noise is being caused by a lack of lubrication, a common cause of low/no oil pressure on these is a fracture of the oil pick up pipe on the oil pump.
Do you think you might have damaged it when you had the sump off, and did you inspect it carefully before replacing the sump?

You could try fitting an oil pressure gauge in the tapping for the oil light sender, which would confirm low oil pressure.

I doubt if there will be anything visible without dismantling that would confirm what the noise is.
 
Took it off because a) the seal had always leaked and was a mess of silicone and gunk b) I’d always meant to replace it but never got round to it c) was interested to see the state of the inside of it and d) I’m an idiot.
10 yrs+ good running ruined
Don’t have an oil pressure gauge but if I can bring myself to face it all again I’ll take another good look at everything tomorrow.
Thanks

Wouldn't beat yourself up about it, whatever it is might have been just about to let go anyway.

You can buy the gauges off the net, think they are only about 20 quid.
 
+1 on the oil gauge - easiest is an old school mechanical one with a capillary pipe rather than have to wire up a sender / electric gauge.
Easy to fit one with a tee piece and that pressure info is defo vital in this case.

That is the one I was thinking of.
If the oil pressure comes up good, then it is more likely something loose in the head and hitting a piston, or a tappet come loose, something like that.
