I've seen several cars with dipsticks blown out too, big deal. One of my old cars used to have a spring and larger O rings to help with the dipstick "ejection"!
I've never seen it on a 2JZGTE though - that's why I asked. I'm not sure if I'm getting the wrong tone from your post but it sounded a little sarcastic and shitty (if not then just ignore me ). I was only asking a question and trying to contribute, not trying to upset anyone...
I've got no seal issues either. Basically everyone is here to try to help each other out through ideas and discussion. I wondered what you knew to back up the dip stick comment - sounds like 2 cases of excessive cc pressure from a blown motor and that would definitely tie up with your theory it's not cc presure blowing the seal - unless the dipstick blew quick enough to drop cc pressure before the seal became dislodged....
