As you might have read, I ran into some trouble on a recent drive: https://www.ferrarichat.com/forum/threads/got-my-355-home-with-the-luckiest-of-radiator-pipe-leak-fixes.581345/#post-146121928 I'm 99% sure it's the return pipe that is the one I field-repaired with some rust-oleum high-temperature wrap (see attached photo). There is some sort of pinhole leak or crack - I haven't gotten up on a lift to see it properly - at the very bottom of the pipe, where you see the tape wrap. It spatters coolant from one specific spot when under high rpm stress and the system is fully sealed (i.e., tank cap tight). So frustrating and baffling that this developed at all. This pipe (https://www.ricambiamerica.com/car-diagrams/ferrari/v6-v8/355-group/f355-m2-7-1995/cooling-system-nourice/158249-pipe.html) is ~$500 at Ricambi, but that doesn't bother me as much as the prospect of its removal and replacement. On my '95, there's a little bit of room to work with up front in the bay, but I'm having a hard time seeing this as anything other than engine-out to really do it right. Only about a year after my last engine-out for the major. Happy anniversary! Anyone a) seen the same problem in the same pipe(s), b) fixed it themselves, and/or c) done so without dropping the engine? If the right way to do this is to engine-out, I'll do it that way. Just hoping it's avoidable.
