This little Porsche oil pump was tired, really tired. The little pump would barely turn and needed a rebuild. Upon disassembly, we found particles, rust, sludge, etc. The magnesium oil pump was completely disassembled, marked for pump set matching and cleaned. After cleaning it was clear that we needed to go a little further. All critical surfaces were masked off and into the glass bead cabinet he went. What came out was as beautiful as the day it was manufactured. All mesh sets were reassembled to their native shafts using the markings. The rear plate was torqued to spec and the pump was pre-lubed. We expect this little pump will make decent oil pressure for many years to come!!!
