Good morning all together! I renewed my oil pump a week ago and made oil change, and since that it rattles in the chain box, but only in the morning who it is cold the first 900 meters, after that it is all quiet again. Could it be by the oil type, I have now 10-W40 in what was in it before I do not know exactly since the workshop has left no slip in the engine room. Has anyone of you already observed this behavior and has someone a hand firm explanation for it ? I’m grateful for every tip. Then I also have a question about the model and the engine. So my Saab is a 9000-der with 2.3L hub and Turbo 170 Ps only approved in 1993, when I ordered my oil pump at Skandix I was a little surprised, because this did not fit the hooks on the small gear not paste together with the hooks on the crankshaft so I sent everything back and ordered me at Schwedenteile.de a wheel set for a year 94-98 and the pa sst. Do I now have a 93-er Saab and have to order for replacement parts for a 94-er ?
