Flush engine with new oil?
(can see my other long post if want to)
If you think there is some debris or any kind of small metal shavings in the engine - can draining hte oil and replacing the filter AND then
pouring in 4-5 quarts of fresh oil help "flush" or "wash" out at least some of the contaminants ?
Isn't there some kind of engine flush treatment Autozone type stores sell ?
Will it make it worse or better to crank the engine over few times or even let the "new" oil to warm up a bit before pulling the drain plug ?
Or is it better to just keep drain hole open and pour a few quarts down thru the engine oil filler opening at top ? And hope for best that some/any bad stuff comes out the other end ?
Is it worth trying ? It's a cheap precautionary measure to try first I think.

If you've ever seen the inside of an oil pan you'd see that it's near impossible to get sediment off the bottom of the pan. What makes you think you have shavings in there anyway? Just change the oil and filter.

run some diesel fuel in with your oil, or a bunch of Seafoam. run the car for 1/2hr or so, then redrain oil and change filter. stick some magnets on your oil pan, and/or on your oil filter, BIG ONES!
you can also drop your pan and clean it out if you want to.

"Flushing" the engine won't accomplish a thing. Anything in the pan should be getting picked up by the filter anyway, and any debris that's actually in the oil passages of the engine will stay there until it eats its way through a bearing to escape.
That engine needs to come apart.

What's seafoam ?
Thanks... what the heck is Seafoam ?
What will adding diesel fuel gas to the oil do for my problem ?
No - I wish I had gotten a look at an oil pan - I was just down at Autozone and got a very good handson look at the oil pump and pickup screen/tube and how the two pieces connect... It really opened up my eyes and learned something (I think)
Man the oil pump itslef is kinda heavy and a big hunk of metal and unweildy sorta (unbalanced)... with a few bolt on holes etc ...
(I don't think I want my mechanic guy to even mess with changing this thing out)
I tell ya all - that Autozone is one of best website (they got breakout pics, manual information, stepbystep stuff) and the store stocks almost every part and stuff and prices are not crazy. It's really great I think.
I'll try the magnet trick thing too.

I always hose clamp a cow magnet to my filter, and I stick a big flat one on the pan next to the drain plug. Pull the plug, pull the magnet, everything stuck there should get flushed out.
Seafoam is a mixture of 50% oil, 30% mineral spirits, 10% water, 10% rubbing alcohol, all avalible in one simple can labled "Seafoam." It will help disolve some of the sludge inside the engine. Personally, I prefer "Rislone"(avalible at any parts store). It works alot slower, but does a better job IMO.
