I noticed i had a slight grown the front of my 90 so when on a little check, greased up all my prop shafts, went to check the oil in my gear box and the drain plug just keeps spinning round and doesn't come out, i know im most likely to have to get the thread recoiled thats not the issue, the issue is my drain plug just wont come out they is even enought space to wedge a screw driver behind it to put abit of pressure on it, any ideas expect grinding the head off are welcome because im well untruely stuck and still not found my grown :doh:
