Anyone know the Oil drain plug size? I drained mine over a month ago when starting the head gasket project and cant seem to find it. Was hoping to get one local but no one including dealer can help out.
I searched here and found a thread that said it was 1/2-20 which is very common size so I ran out and got one but its just a little too small. Maybe its a 9/16? Or metric since most every thing else is.
I have a 99 D2 with the Bosch

Thanks for reading
