does anybody know what the correct helicoil kit is for the sump drain bolt ? was doing oil change etc and the thread has had it so gotta repair the thread , i know its a 14mm thread but there are a couple of helicoil kits with different thread pitch etc so dont want to buy wrong one . if it makes any difference the sump bolt is one of the magnetic ones not the original and its an 02Â Â 900Â Â . cheers guysÂ
