My project 1966 C15 had the engine rebuilt in 2016 after an oil pump failure. The rebuild included having the flywheels trued up, new main bearings and oil pump. The bottom end was assembled by 'London Classics'. The engine has not yet been run.
There is nothing to indicate whether or not 'London Classics' or the owner cleaned the sludge trap.
Is there any way for me to see if the sludge trap plug shows any signs of having been disturbed, without splitting the crankcases? Would I be able to see down if I removed the barrel?
Also - is there a way of checking the crankshaft oil passages are clear, without splitting the cases?
Yes, you can see the sludge trap screw with the barrel removed 👍
