I have a new to me early 74 that I’m tinkering on. The engine will start but has some pretty obvious knock problems. I took the pan off and have spent the day trying to clean and identify the metallic Sludge and oddball fiber bits within.
I haven’t found anything obvious from the top valve side nor from the bottom crank side. Metallic sludge, some, appears in the oil screen as well.
Thoughts?

His many Miles on the engine
What oil pressure
You can clean it out and replace the 3 mains you can get at and the rod bearings or depending on miles and pressure rebuild the whole shebang

The black chunks may be timing chain tension shoe.

31,451 on the odometer. Presumably 131,451? But there is red rtv gasket at most of the gasket points I can see - so someone has been in it at least once. The car was definitely someone’s project. For example, the side chrome has been replaced with glue on trim.
Oil pressure on start and idle was 40 to about 70 if I recall.

In pic #2, is that a castellated nut lying in there? Hard to tell size without reference, but if it is, I would say a dpo has done some major poor repairs or careless wrenching and not cleaning the pan after you lost a nut in there!
Agree that the black stuff is prolly the tensioner.

been a dpo myself...

Dissolve that sludge in place with some solvent and check it with a magnet to see what sticks.

Also, keep in mind the block's galleys and oil passages have the same crud build up.

From the factory there were no castellated nuts inside an MGB engine.

Now if it were an E-Type Jaguar... cool smiley
