Re: Long block failure on a Volvo D3-110 Amel 54-152

Black smoke is caused by unburnt carbon....oil burning is blue smoke.
Unburnt carbon usually indicates there is a blockage somewhere
Airfilter..you checked that
Injectors..you've done that.
Another thing could be too high back pressure in the exhaust.
Has the exhaust system been taken apart and checked to be sure it is relatively clean and free flowing?
