OK heres the latest.... I checked my oil again and I was 2 quarts low! Just a few days before I was full but then I took a 3 hour drive on the freeway at about 3 grand the whole way. I filled er back up and it got a little quieter. Also adjusted valves but seems to me to be really loud in the morning when I first start it up still. I think the fuel pump was leaking oil so I changed that. No time to change oil yet. When I do an oil change, I heard 4 quarts. Is that right? With or without filter?
