Dont know how many of you have ever heard of the toyota D4 direct injection engines (2JZFSE 1JZFSE etc.) But this post isnt really about those. This is really crazy so I will simplify it. Are there coolant passageways right below valetrain or anything? To understand where I am really talking about is this. If I were to find a space where you could "drill" a whole into the cumbustion chamber, would I be drilling through coollant passageway or just solid aluminum? Note that this whole needs to be purdey damn big bout the same as the wholes for spark plugs. Thanks!
