Smoke and diesel knock after warm up
While cold perfect (about 5mins). Then smoke with loads of soot in it. After further few minutes a diesel knock and missing lumpy drive. Not sure if it's fuel related or head gasket/ cracked block etc.
It's started while driving along. Fine, been driving for an hour or so then loads of smoke suddenly and a very loud knocking noise. But when cold runs without any noise so I assumed it's diesel knock.
Any ideas would great cheers.
