The engine cleaned up pretty nice. It also looked pretty clean from underneath. The oil pan was sludge free, but I replaced the oil pump and shaft anyway.
This was quite a pain in the ass as well. I had to remove the sway bar, steering drag link, and a cross member that goes under the pan. Everything went back together OK except when I went to reinstall the cross member the bolt hole had stripped the threads OFF from rust. They're gone. NOT GOOD on a unibody frame car with NO ACCESS to the inside. I had to order a 1/2-13 helicoil kit. Probably won't come in until after the holiday
But I did get the pan cleaned up and back on! I used the new $$ one piece felpro gasket. Worth the money!
