I've had a chance to pull the motor out and there's quite a lot of work to be done, not only with the sump. I've decided I will most likely replace the sump altogether as it's basically a piece of junk to put it simply. It's been cut and shut that many times that I can't bring myself to cut and shut it again to repair it.
The water rail will probably also be replaced, it's not the greatest.
I'm taking to the inside of the intake manifold runners with a die grinder, because they are some of the worst put together things I've seen in my life. Pigeon sh!t welds everywhere, they would flow horribly.
It's also an excuse to clean up the throttle body, it's covered in pigeon sh!t welds too.
The big kick in the guts is the gearbox is fairly shagged, the input shaft has about 2mm of play in all directions and the gears all need replacing. So I'm doing an unexpected 5spd conversion.
These things happen when buying an unfinished project. I can't complain though, because I was only weeks away from rego, and if I didn't have to pull the motor out I would've been putting the car on the road with a dodgy gearbox and it could've let go at any time, leaving me stranded. My mother always told me things happen for a reason, hahaha.
