I have a feeling I already know. Engine has ~900 miles. Haven't pushed it too hard, am extremely paranoid after having a rod bearing spin after 800 miles on previous "refresh".
Car drives great, its on e85, extremely responsive. Was getting some false knock since TA header was hitting passenger a-arm, so not knowing if it was real or false knock, I've been pretty easy on it. Saturday a buddy helped me swap upper a-arms for tubular ones. Before we even started there was a puddle of antifreeze under my overflow container (stainless hot rod type, because I used to run methanol inj) after we got the arms on, we take it around the block and that's when I get in it pretty good. Appears most all previous knock is false and at 23#, it shows 1° of retard since it seems I'm out of room with 80# injectors and the 6466 won't go any lower (yes, I ported wastegate hole before first start) I'm going to try a new radiator cap, but I have a feeling a HG already let go, since there was nearly 900 miles on the build and it never dumped antifreeze out overflow before. They're rjc bullet proof gaskets with ARP studs. No oil in puddles of antifreeze and oil looks fine. Any other ideas?
