keep us posted,

The 300 is the next one of my "keepers" due for an oil change. I do one of them each year. Neither of them will even be started again for a few more months yet. I've been on the 3-year system for the Chryslers and am thinking of going more than 1 year on the '62 Buick. I'll skip this year and extend to 2 years on that one and see. It's a different animal than the Chryslers.
The Riviera had been giving me regular start up knocks that would last for minutes and I was thinking the engine was getting really worn, even considering unloading it. I did a lot of tinkering with it over the last week or so including: plug EGR valve hose, replaced PCV hose, breather filter, cleaned PCV valve, turned back idle 1/8th turn, and changed oil filter, but not the oil. Now, except for rear seal leaking, it starts smooth and quiet, no "dieseling", and no pulsing at low or part throttle.
PCV hose was hard as a rock and not sealing well. EGR valve was not working smoothly, leading to the pulsing miss at part throttle. This caused the erratic steering as engine speed determines the effectiveness of the PS system. Blocking off the valve led to slightly increased compression, causing the "dieseling", which backing off the idle cured. I removed the Fram PH-25 and it was empty. Not one of my old pre-grippy ones either. I replaced it with one of the Purolater FL-30005's I had that were too long for the '62. I didn't change or drain the oil, or even pre-fill the new filter. Just lubed the gasket, installed it, and started the car. No knocks at all, even without a prefill. No more Fram on those engines for me. I drove it around through 5 towns today in various types of conditions and the Riv finally responded exactly how it should.
I'm still waiting for the Dr. to discuss my options after the EMG testing I had Friday. They detected compression of the ulnar nerve when my elbow is bent. No trouble when arm is slightly bent or straight, so at least no nerve death.
