Hi guys, looking to see what size this bung is. I really need one and completely forgot about this. Being it 5am in the morning, my not-so-smart idea to plug the hole was with a bolt that (a) didn't fit, and (b) had some high temp gasket seal around the head of the bolt... figured it would work. Doesn't work so well when you get into the higher rpms
So, I've heard that the bung is M12 x p-1.25 - no idea what this means, and I can't seem to find any stores with it... if you're familiar with it, let me know... otherwise may take it to an muffler/exhaust shop and have them weld it closed - would prefer not to do this unless I really have to.
PS: Q300 sounds a bit ricey.
