My suggestions:
1 - PLEASE for gods sake blow your motor up. I hope to god it dies on you. Driving at 250km/hr (if your actually telling the truth about it) is absolutely stupid. Not having a motor will put an end to that. This will solve MY problem i have with you.
2 - Mix up a large batch of JB Weld (1L or more) and put it in with your oil. It'll add some thickness to your oil, stopping it from spraying all over the underside of your hood. Once again.. this will solve MY problem.
3 - Rebuild your motor and get a good understanding of how shit works, and in the process hopefully gain a bit of maturity to understand that you'll never bag on something you really love that badly. This will solve YOUR problem.. hopefully permanently.
Go drive on another road other than the one i drive on thanks...
P.S. Dont actually put JB weld in your engine.... only Robin can do that
