Stripped the sump drain thread!!!!!

[Volvi]

Wardsy, Im pretty sure you cant remove headers till you remove radiator, chances are you havent changed rad fluid since new and may be time you did. so yes remove rad and flush the whole system. I used Hondas anti freeze @$9.50 x 4 bottles. (made a thread on it somewhere)

Headers might recommend you use new washers x 4(those metal rings).

Sump, thouroghly clean gasket surface on sump, check oil basket whilst there. Tighten sump screws evenly, beware there are a few screws with different lengths to match its position. And last but not least screw sump plug in with NEW washer which has to go thru its crushing, sense the crushing and sense once crushed (feels different torquing) and off course dont over tighten when post washer crush.

Do everything as a project allow yourself plenty time if you can ie not rush everything in a one lot job. Always take a brake when experiencing "brain farts".
