Found an old thread from 2010 in the archives that was informative;
http://wildguzzi.com/forum/index.php?topic=34750.0 But my problem is somewhat different, and I'd apreciate any advice.
I bought a Corsa last autumn, and now I've rounded 30.000km and it's time to greaze the drive-shaft. The PO informed me that one of the nipples are defect, or at least very hard to greaze. In the contract, he allso supplied me with a spare drive-shaft, that he bought used from the Netherlands and hadn't bothered mounting. I'm now beginning to look into the manual, and considering swapping the drive-shafts, but now I have discovered that the "spare shaft" haven't got any nipples???
Does that mean that it is a drive shaft from an old Daytona, or am I blind?
Should I swap the drive-shafts?
If NO, is there an alternative way to greaze the joint where the nipple doesn't work on the original shaft? Where excactly does the greaze go? Is there a way to buy a new nipple?
And while I'm at it, the manual allso recomend that I readjust the valves and take out the bottom of the oil-pan, to clean the filter there, changing the gasket. Do I need to buy a new gasket, or could I just try with the old one, and see if it starts leaking? Do I need to do the valve-adjusting-thingie, when I think the engine runs fine with no ticking?
