Good luck Lee, you deserve a break with that damn car!
My lodger did a rebuild on his Cossie lump years ago. Craned it all back into the car and did it all up.
Then saw the rear crankshaft oil seal still in the gasket pack
Engine out again, seal in, engine back in again. Still going strong 3 years later
Sure things will be the same for you, bit of graft now will be worth it when it starts to make the numbers
