Aaron Sedgmen writes: Upon dismantling the case I discovered writing <VW logo and some numbers> on one of the main bearing journals <no. 2> which suggests to me that the case has not previously been align bored. Does this logic hold true for those in the know? ----------------------------------------------------------------------------- According to "How to Rebuild your Air-Cooled VW Engine" the writing you are seeing on the case will correspond exactly to what is written on the back of the bearing - It has been "printed" into the case by the pounding of the crankshaft. It is an indicator of the need to do a line bore, not whether one has been done already. The book also says to check for fretted material on the case at the center journal parting lines as an indicator that a line bore is required. When I took apart my 1800 it also showed the bearing markings in the case but I saw no evidence of fretting. What I did find disturbing was that I could rotate the #1 bearing slightly in the case when it was still bolted together. This says to me that the case was distorted enough that it wasn't "clamping" that bearing tightly. BTW, it was a rebuilt from VWoA and hadn't been line bored. Good Luck, Dave
