yep, that's what i do when i change my oil, works great.
and my filter relocation helped a bit, but i'm sure most of the difference is that i mounted my filters vertical instead of horizontal like on the engine was. at least i can now prime my filters. for the most part my knocks are gone, but like i said, when she sits a while over the weekend if you dont crank it a bit beforehand their will be a split second noise.
pretty sure the damage was done, when i got her their was a ACdelco filter on.... knocked right their on the dealership lot for like 10 seconds. these people knew i was coming and im not about to think they weren't smart enough to send someone out to start her beforehand. the motor was slightly warm already.
who knows what the original owner was running for the first 118k but since their is a knock, most likely frams or whatever cheep junk came at the local jiffylube.
i know she was PACKED with sludge. i didn't remove the valve covers, but i could see it thought the fill cap, and the first Mobil1 change i performed burned horribly and drained like brown chunky dek-a-cake icing... only took 4 quarts too, which was worrying.
changed the filter at 500 miles and it was packed with turds. had to add 2 quarts at 1500, changed it all at 2k for some syn blend. next couple oil changes were still pretty filthy, but shes spotless nowadays and takes a good healthy 7 quarts.
oh and one thing i was going to mention about frams was those ecotec chevy engines with the internal filters. i used to see those completely collapsed into the filter cap constantly. and i noticed they are slightly taller then the OE ACdelco filters for the engine so when you tighten down the cap it crushes the pleats slightly.
