A few notes on pump R&R and Smoke

After seeing a VW 1.8T timing belt that had almost shredded itself due to a bad water pump sprocket bushing, the importance of lining up the pump sprocket and the camshaft sprocket comes to mind. Line up a straight-edge with the camshaft sprocket. it should line up perfectly with the pump sprocket. This is only really necessary if you remove the pump mounting bracket or if your rear belt seems to be wearing prematurely/unevenly.

Regarding the smoke... I seem unable to get the Volvo to smoke even if I mash down the throttle and am running petro diesel. This is a good thing. It might be due to the new pump timing setting (0.75mm), injector recalibration (155 bar) or the rebuilt pump or a combination of the former. Whatever it is, it's good news.
