I have recently purchased my van and I am having a bit of trouble identifying exactly what engine is in it. It is a 1.6td supposedly from a golf, however I can't find any engine identification codes! I have found lots of different numbers (pictures below) but I think these are just casting numbers, any help would be greatly appreciated!
The engine also has a few issues, leaking oil and fuel, as well as the exhaust being very white





Thanks
