tomson1355 Posted March 9, 2005 Share Posted March 9, 2005 Arne, A is the uppermiddle bolt. B is lowermiddle. C is upperfront and D is lower front. Eis upper rear and F is lower rear. The first four steps are in alphabetical sequence. 1.Tighten all bolts to 22 ft-lbs. 2. Tighten all bolts to 51 ft-lbs. 3 Back off all bolts by 180 degrees. 4.Back off all bolts by 180 degrees again. 5.Tighten bolts A and B to 25 Ft lbs. 6.Tighten bolts c,d,e and f to 11 ft-lbs. 7.Tighten all bolts by 80 to 90 degrees, alphabetically. 8. Repeat step 7. Hope this helps. Tom Quote Link to comment Share on other sites More sharing options...
ahalseth Posted March 10, 2005 Author Share Posted March 10, 2005 Hi Tom! Thank you! This was the "missing link". I had to change the oil pressure ring in cylinder nr 2 at 135 000 km. Strange, all the other cylinders are OK. Greetings from Norway Arne Arne, A is the uppermiddle bolt. B is lowermiddle. C is upperfront and D is lower front. Eis upper rear and F is lower rear.
