I own a 91 foxbody and need to replace the oil pan gasket. I know how annoying this is going to be because it's old and the gasket will need to be scraped, and if I don't lift the engine and just replace it through the small clearance the old gasket parts will fall into the oil pan when scraping old gasket off. Does any know if I could just angle grind this factory curved oil pan with two sides to drain oil, and replace it with a slanted one where it can slide in and out without having to lift the engine just to replace the gasket?
