thanks for all the replies, how can one determine if the timing in the pump is a litle late?
and if that was the case why does it sound perfect when you first start the engine.?
I did used the old returnd lines but there only 3 months old. I'm taking the injectors out tomorrow to make sure everything is clean and the heatshields are ok. I did see a litle bit of smoke coming out of the injector # 1 and #3 it seems that 30 ft/lbs is a litle low for this.

30 ft/lbs is preaty close to 40 nm right.
