I,m rebuilding my 2.5 engine & as matter of course I replaced all the crank bearings & thrust washers...only 1 thickness available...built 1000,s of engines...never seen 1 with thrusts on only the bottom of the crank...my problem...I have no side clearance...checked the clearance in just the thrust half of the crank casing ... measured the width of crank & then the housing with the washers & every time they measure exactly the same...NO side clearance...do you have to reduce the width of the washers by rubbing them on emery paper...not a very Porsche thing to do.
