our car starts and runs but there is a noise from the engine.

What is your question?

Could the problem be the rod/piston. We want to sell the car but so far potential buyers are afraid to buy it because of the noise. The inside and outside is in very good condition. There is automatic transmission and steering, am/fm radio that works, airconditioning needs frion. Battery is one yr, old. Drives around area, 88000 miles. red four door sedan.
