G'day Paul, l have just a mouth ago pull down my lightning engine and after 63500 miles the crank sludge trap was about half full, l change my oil and filter every 3000 Miles this is the bikes first pull down since new in c1966, it's getting the works this time full bottom to top, cheers mate Neil 🤠.
The cranks looking sound considering the blow up. I was watching a Chinese woman on UA-cam ,who repairs & bodges up her villages motorcycles & farm machinery . I reckon she would of attempted to straighten out the bent cam ,with a blow lamp ,2 lb lump hammer & re- profiled the cam lobes with a 10 inch bastard file. I am glad she can’t get her hands on my bikes . 👍
@@highdownmartinShe also does a nice line in instant cylinder rebores with an electric drill by eye , & grinds the carbon off piston crowns & valve faces with an angle grinder . That’s doable also & only guaranteed until she has had chance to pocket the bunce & make a quick exit .
There is footage on u tube in the shorts section where all sorts of lorry engines get welded back together.....makes me petrified to think how many people died when buses suffer this boge mentality
I have a very early SRM timing side conversion (no 81 done in 1984) and it's never been apart since...I run a spin on oil filter and 20/50 oil .seeing his I do wonder what I am going to find inside......
Might help it to stay in solution. Maybe not. Centrifugal forces are pretty strong which is the point in sludge traps. Best insurance is a return oil filter on these (my opinion). Then the buildup in the sludge trap will be slower. Interesting how the sludge builds up on the far (LH) end of the sludge tube first! BSA feature.
When my Triumph Tr-6 was 40 years old we had to replace the camshafts. The sludge trap was almost full. We threw it away instead of cleaning it. It was only a $7 part. God knows how many miles were on her. She's good for another 50 years.😂🎉
Thank you for making this series of videos so fast. Everyone was anxious to see what the damage looked like up close.

That's interesting, thanks for that Neil.
65 k,wow!
I always assumed the caked sludge was more due to the dirty,older grade oil.Interesting.
Thanks Paul.
very interesting....great info...keeping your oil changed is a must

Needs must…
Probably doable though. If it needs fixing and there’s no other option there’s nothing to lose

I have a 1969 BSA unit twin.
I fit an aftermarket oil filter kit that uses an R3/Trident cartridge.
Cheap insurance
Seems your picture hanging skills are second to none. That picture had to be hung on that spot on the wall whether the pipe was there or not 😊
That is a picture of my Grandfather's filling station near Shrewsbury.

Pretty much as one would expect.
Rest of engine looks good, to me it all points to con rod failure and nothing else
Have you considered getting it balanced by someone like Basset Down? They could check to make sure the two big ends are still on the same axis.
No return filter?
Something positive
👍👍
Would Marvel Mystery Oil - or its local equivalent - help with sludge on these??
