Porsche 912 Engine Case 1969 69 # 4096499 There are markings on the case indicating that someone measured it, I cannot guarantee that is accurate as I did not measure it and did not write that. Sold "as is". The tag says oil pump housing NG I assume that means no good, I have not measured anything but I dont see damage other than one broken oil pump stud. I have other 3 case pieces and you can substitute one of my other ones if you want, let me know.
