How to remove check valve in M50 cyl head?

[Jon K]

Hey guys - just wondering how to remove the check valve that is located in the M50 cylinder head to keep oil in the head. I have a replacement but left it at the shop and trying to remove the one in my current cyl which is here at the house.

Thanks guys.

Winfred - I turned the thing CCW about... 60 degrees and now its what I'd call "loose" but it doesn't seem to want to come out.. am I missing something?

[Jon K]

yep

It feels like it has resistance after about 60 - 90 deg CCW
