Hey All,
Doing a head gasket job and I finished the head bolt tightening sequence per the 29 ft lb and 90°, 90° method and something felt strange. All head bolts tightened properly, but two of the bolts felt like they had slightly less resistance on their final 90° turn. The two bolts felt like they had slightly less resistance on their final turn.
Is this acceptable? The bolts are brand new OEM parts. I've searched and found two threads where that was discussed and there were opposing views: remove and start over OR just keep going and run it.
I was super careful with this method and I am wondering, is this the head just adjusting to the new tension or is there a legitimate problem? If I remove the bolts again and start over, will I need a new head gasket?
I chased the threads with a bolt and they were clean and and I cleaned them out prior to and cleaned them with brake cleaner and blew them out dry before I did anything, put a light amount of oil on the new head bolts prior to torquing them in place.
This is annoying me and worrying me. Any thoughts?
Thanks
