I replaced the motor awhile back. The 302 engine has now started with blowby and a knock. This just suddenly happened, why?How to fix and is it costly?Thanks

Check for il level being full and pcv system being blocked. It may have detonated then preignited and burnt a hole in piston. It really needs disassembly to see what is wrong and how good was the motor when you installed it?
