Oil Flush Question
Oil Flush Question Hey Guys,
Well, I'm having my buddy do a HG change on my car b/c I have zero time to do so. He didnt realize that I hadnt drained the contaminated oil yet when he got it, so he let it sit while we waited almost a month for the heads to come back from the machine shop. When he drained the oil yesterday, he said there was a **** ton of chocolate-milk looking oil that came out. So its possible that the crankcase was submerged in that **** for a month.
My question is: does my shortblock have a snowball's chance in hell of survival at this point? If I flush the crankcase with some cleaning solution, will that clean the bearings, or are they probably already fucked from pitting and corrosion? Any help or advice would be greatly appreciated. Thanks.

Hey:
Just flush it with some lightweight 0/20 or 5/20 cheap (Walmart) brand oil, let it sit for awhile, maybe a few hours and drain, repeat till it comes out clean oil, put in new good oil (Your Fav) and good filter (Wix, NAPA GOLD, Mobil1, or K&N to name a few)Not Fram, and you should be GTG, Change filter on a short cycle soon JMHO. Also you can try a marine engine flush like Seafoam in the crankcase, and Mopar CCC, for the combustion chambers once you have done the basic oil cleanse, if you still need it cleaned.
Good Luck on you project.

I was thinking of using the Amsoil engine flush cleaner. But I've heard a lot of people say Seafoam is the best, so I might go with that. My main concern is corrosion of the bearings from it sitting for so long.

I'd use a product called Essentialube, made by Hydrotex. Use at a rate of 2 oz per quart of oil. Use it with some cheap oil just for the flush, then put some good sythetic in there. If it works, you're home free...if not, you aren't out much.

I wouldn't use any flush chemicals or solvents. You run the risk of knocking any sludge buildup loose and sending it straight to the oil pump pickup screen, clogging it (resulting in exactly what you were trying to avoid). I would just get 2 cases of el-cheapo oil 4 filters (NOT FRAM!!!) and change it 2-3x while it is still on the jackstands, take it around the block easy a couple times and change it again, then drive it easy a day and change out for good oil.
