My headgasket went out on me today. I already have the gasket kit for the engine. Initially thought that I had to replace the headbolts but I was told by a bmw dismantler that the M30 and M10 do not have to have the headbolts replaced. Just wondering if anyone can verify this. Also wondering if anyone has any experience with this. I have a bently manual, but sometimes they miss things. Also if there are any specific things I should be looking for.
