Yearly oil change today. Old oil wasn't terrible, but was definitely dark. New filter, new Rotella 15W-40 oil. I had to toss the old copper crush washer, NAPA had no replacements. So I had to get a fiber washer that was close, then modify it to work. No leaks so far.
Also checked the vacuum pressure on the engine to check my idle mixture. I replaced the old vacuum hoses with new ones, as the old were all cracked and hard. I didn't have an adapter to fit on the carb, so I connected to the hose going to the vacuum tank. Is this giving me a false reading?
At idle it was showing 18-19 steady.
