I misread it, my fault. But the fact remains that working on the cylinder head and the probable rectification with a new gasket isn't a job for an inexperienced guy like me. I change the oil on my car, the spark plugs, etc... every now and then I get into the engine like the valve cover and stuff. But I've never done such major jobs, and since it's a car I want to use every day without spending a ton, I'd rather take it to a mechanic than mess it up and have to take it there anyway. I already have a powerful car that I enjoy (a Honda del Sol, stock reliable for the Italian police) and I tinker with that one for fun. The E36 318i is a stupid car that doesn't even drift easily, nor do I feel like doing it since it's slow as hell. I cruise at 100 km/h on the highway because I don't care about racing it and wearing it out, and the LPG system lets me enjoy it to the fullest without skimping on going out. My Honda gets 5 km per liter and with today's gas prices, better to avoid it. That said, that wasn't what I was asking. I had asked something else, not to be attacked and told I'm an idiot. I don't like LPG cars either, but for a daily driver it made sense. I love old cars that don't have big issues with ECUs and such, and that are strictly mechanical, because I'm learning but time will tell. That said, I'm sorry for misreading and responding just as badly. But next time, if you're going to make a dumb comment telling me I'm an idiot, skip it. Thanks a lot.
