Behaving badly

[Steve Tinker]

Good luck with that - there's little space in the tube orifice to get a boroscope in let alone angled tweezers as well. I suspect there is no other option to removing the cam cover to clean out all the debris, though dropping the sump will give you a good idea how much plastic has been chopped up by the camshaft and oil pump and how much is still left in the cam cover.

That may allow me better visibility with the borescope. It's 5.5MM so I should be able to get it in and around ok. That will also allow me to inspect the scavenge pump to make sure it hasn't eaten anything yet...
