Re: Question about oil in distributor
In addition to the previous advice, Is this the first time that you inspected the distributor closely? Or in recent times? Maybe it's been full of oil for some time. Is there oil in your air cleaner as well? It's not uncommon for an older engine to wear to the point that blowby pressurizes the crankcase and drives oil out at every opportunity. Make sure the crankcase is properly vented, no hoses plugged, and use a catch can for any oil coming out the pcv vent, if necessary. Keep the pcv system, it is beneficial in several ways.
I don't see any relationship between doing the nutter bypass and having a knock, if you set your timing to the same total advance as before. You probably are getting more advance, as the original computer, now by-passed, had some detrimental role in the performance. If the springs are screwed up (and I can't figure out why it didn't cause a problem before the nutter bypass), that will certainly cause a problem.
I'd clean out the distributor with solvent of excess oil. Not sure what you mean about the springs. Both mechanical advance springs were identical on my distributor. I'd stick to the stock springs unless you want to spend time setting up a faster curve and playing with initial advance. Are the springs off on one end or stretched out permanently? They should have good tension when installed. If they are suspect, perhaps you had better install a new pair of springs. Available from dealer or parts store? Not sure myself.
