yanmar 4300d rebuild

[jamesinms]

The 3t90t engine just got a new turbo, we put a garret t3/t4 on it. It ran fine for 10 hours now it seems to flood out and has blown small aluminum peices from the exhaust. I took the turbo off it was not damaged and tractor ran the same without it. does this sound like a rebuild required and where can i get a kit
