If you have an oil leak on your engine, the first thing you should do is clean it. This will stop the oil from seeping into the engine and causing it to overheat. You can do this by using a plunger to push and pull the oil out of the area, or by using a vacuum cleaner to suck out any liquid oil. If you can’t get the oil out with these methods, you may need to use a vacuum cleaner with a hose attachment to suck out the oil.
