@Vo @sapphire @prettygood You should always be able to see ground through the engine bay. My old college roommate had an old boxy Soviet looking Volvo. He bragged showing me 1 Philips screwdriver & 2 wrenches saying that's all you need to work on this car no matter what. He was right, he never asked to borrow a tool when it later dropped a valve & he had to pull the heads off for remachining.
