Hi experts,

recently I bought a 98 Cherokee 2.5TD Sport which throws out black smoke on
accelerating
and a black cloud when passing about 2000 rpms. Maybe this is a known
problem or just a 'feature'?
Any ideas what I could check?

A second small question: maybe somebody knows where to find more details
about the VM 2.5 TD motor,
a repair guide or service manual?

Thanks for any help,
Dirk
