I've read the previous posts and my problem differs slightly from the others in that my 2003 Volvo D2-55 blows wafts of white smoke when she is loaded up.
The smoke has only just started occuring and only appears although suddenly at around 3/4 revs - the smell is like slipping belts (burning rubber like smell) although it can not be as the belts are tight and it is coming out of the exhaust.
Oil consumption is relatively low 100hrs at variable cruising revs drops about 1/16 on the dipstick.
The oil was overfilled by the previous mechanic to about 1/4 over full when I took ownership a year ago and the problem has manifest since I drained the excess oil (taken down to around 7/8 of full).
Can anyone steer me in the right problem solving direction, I'm pretty handy although do not have any diesel mech tools such as comp testers etc.
Thanks in advance all,
