Help Marcin replace the engine head gasket and return to work

I make my living with my delivery van. 7 weeks ago the engine head gasket failed, and the mechanic says the repair will cost $450. Without the vehicle I earn nothing. I have been borrowing from friends to pay rent, and now I have run out of people to ask. I support my wife and our newborn. Before the breakdown I worked ten hours a day, six days a week. I have been offered extra shifts for the next four months if I can just get the vehicle working. I have a written estimate from a certified mechanic and will upload it here. I'll pay the mechanic directly and show you the repaired vehicle in an update. Where the $450 goes: • engine head gasket replacement (parts): $240 • Labor charges: $110 • Road tax and insurance renewal: $60 • Towing and inspection: $40 Every share and every dollar helps. - Marcin
