Use what ever you prefer, bear in mind theres a good bit of handling to replace the sump so expect some on the hands ,
worth a look at the timing cover seal while your seeking leaks, then it goes on to timing chains
where to stop , or leave well alone ,
with the sump off use a small ball pein hammer and strike with a heavier one and drift the flange holes down from the top, with age the bolt holes distort where it crushes the gasket , you need to make it flat or reverse the distortion
so give all holes a good whack
