Hello first, I explain my problem to you. I bought a Pc37 from private and had everything done chain, tires, oil etc. the seller said inspection was made after I had everything done in a workshop (except spark plugs), I wanted to make a tour and after 20km I pulled a smoke cloud after me. The workshop says that from the spark plug the electric is broken and came against pistons that follow, hole in the piston! ?? Now I have found an engine, but from 05-06 series, can I install it without any concerns, if I take over the injection insert etc. ? Bzw can I take over the injection insert ? Or does someone who knows someone who would repair the engine cheaply ? ?? I thank you already for the answers.
