I have a 2004 Kia Sedona and it has been sitting now for about 4 months because I had a knock in the engine and a loss of power. A local church group has a car club that fixes broken vehicles for people and I took it to them. They removed the shroud that covers the engine and a piece of carbon flew out from on top of the piston and the rattle stopped! I was excited the van seemed to be running good for about 2 weeks and then it happened again. I hate to call on that group again and was wondering how can I fix this myself, and what is causing the carbon build up?
