I wasn't saying I am not going to do the studs first. I was only getting back to the topic which is not regarding the oil leak itself but the question if one can re-torque the head bolts. If I don't have to do it, great, but I was thinking anybody looking at this topic later on might also want to have that info, me included. - maybe I was too thoughtful
anyways, thx for the extra info. So I know now that just re-torquing without pulling them might cause more issues than provide a solution.
An additional question regarding that: Can you pull one by one or could this cause head warp or leakage and then I'd have to pull the head off anyways? I read people switching to ARP have done it one by one but it sounds scary to me.
