I was fitting an oil pressure tester to the engine, and while removing the pipe from the turbo that goes to the oil pressure sender I dropped the nut from the bracket into the slot between the gearbox and engine, at the top. It seized the engine. Luckily it fell out when I removed the flywheel cover. Is there a plate I should have that covers this slot? It's about 3" long by 8mm ish.
I'm considering sticking some silicone on it.
