I was wondering if anyone else had experienced the same mechanical problems as I'm having right now. My car has just been diagnosed with a head gasket leak (it's leaking oil), the transmission pan also leaks, the oil pan is rusted. The mileage is at 152 000km. Is this normal wear and tear, should I get it fixed. I'm also curious as to how the heck this could have happened, what causes a head gasket leak.

Thanks in advance for your replies.
