Water is getting into # 2 cylinder on my 4.9 litre engine.

I've been doing auto repair for 43 years, never had any of that 'snake oil' to fix anything for more than a week! .. It'll just start leaking again and then you may be in the middle of nowhere.. Good luck if you decide to try it! .... Maybe I just read the instructions wrong all those times I tried it. The only way I could ever permanently FIX these type problems was 'mechanical' repair!
