440 gas Oil filter nut...

[440 iron popper]

Normally we don't have to touch this... Even I kept break cleaning the bowl of the oil filter, dirty stuff never stopped coming out. So I did like the book said and pressed the nut out. I found out a lot of sludge under the sealing plate and a rusty spring and rusty washer in there. The book says I have to use a special tool to ''reform'' the sealing lip when installing.... Did someone ever do that without the tool and has a trick? Thanks,
