Felix Posted December 15, 2010 Report Share Posted December 15, 2010 Were the thrust bearings and oil pump gears good? You could try shimming the bypass spring on the oil pump. Quote Link to comment Share on other sites More sharing options...

eberbs Posted December 15, 2010 Report Share Posted December 15, 2010 (edited) sump must be off/dissy removed. remove oil pump securing bolt (1 10mm bolt) remove the split pin SLOWLY spring will pop out with like a washer. all 3mm of spacers (washers smaller than 14mm wide if i remember correctly) push the spring in with the tip of long nose pliers insert the NEW split pin and wrap it around the oil pump HEY PRESTO Found this using the search function. Shimming means: http://en.wikipedia.org/wiki/Shim_%28spacer%29 Edited December 15, 2010 by eberbs Quote Link to comment Share on other sites More sharing options...
