I put 85-140W gear and Lucas stop leak on both sides of the suspension and have one very small leak on the driver's side. I still have a large leak on the passenger side and have to see why it leaks.
I changed the rear pinion seal and it was very easy. The differential pinion nut is a 30 mm hex nut.
I am going to change front and rear engine gaskets next and hope to be finished with this car.
I also helped the owner to rebuild the two carburetors. The carburetor bodies are used on VW and on 356 Porsche but, the internal parts are all different.
This is the first BMW that I have every worked on and was lucky enough to find parts from Germany. I know that some Alfa parts are expensive but, parts for this car are very expensive.
