Rods, bearings, rings
 

How do I determine replacement size of crankshaft & rod bearings, and rings. Plan on rebuilding 2.7 from 2001 Boxster Tip with 100,245 miles. Daily driver I put last 69,000 miles on. Found less than 1/4 teaspoon of green plastic bits from cam hole plugs in oil filter and 3 tiny bits of brown plastic chain ramp in oil sump cover when removed. Plus one tiny metal flake half the size of toddler's finger nail clipping.

You don't have alot of choices, only one size bearings are available, standard diameter. There currently are no other sizes available. If the crank mikes out as being worn, you need a new crank.
