Egge Pistons and Aluminum Heads
Our 48 V-12 was assembled with Egge pistons and Hogan aluminum heads, resulting in a terrible knock. Upon removing heads and intake, notice a mark in no. three chamber where swirl casting likely meets domed piston. What to do:
1. Get new pistons, if so who makes 2 7/8" pistons, 0.060 over?
2. Modify piston, is so how?
3. Use two head gaskets? Maybe additional problems.
4. Other suggestions?
I understand grinding the swirl casting would not be recommended.
