Hi,
Just beginning my journey of a top end rebuild and just got to the point of removing the chain housing. But that leads me to 2 questions -
a) I realized after opening that housing that the CAM is STILL using the "old" style nuts - 46mm nut requiring the crow-foot Porsche tool to remove, instead of the "19mm screw" type. According to Wayne's book, the change over was around 1980 & mine is a 1987. So... does it mean that someone (PO) might have replaced the CAM? With the fan off, how could I test the camshaft profile now, ro do I need to?
b) That leads me to take a look at the "new" camshaft I bought quite sometime ago (in preparation for this) from ebay. I noticed there's a nick in the bearing (one closest to the rear of engine / chain housing)... DUH! Yes, I know I should have taken a real close look when I first got it. But now - what do I do? Is it still usable? I am thinking I should at least magnaflux it?
Thanks...
