So, I have a main cap (girdle) stamped pg6 for my z6. The problem is, when I torqued it to spec 18 then 38 , my crank would not spin. Ive basically soaked this thing in lubricant by now and it still is not wanting to spin at 38. Just to check it I spun it at 18, no problem, even at 30 it spun but at 38 it will not go. I am wondering if I have the wrong main cap? or if it is a problem with my thrust washers or something completely different. Any input is appreciated.
