Engine sludge, to flush or not to flush? (22re)
Just picked up a sweet 88 2wd last night with only 129k miles on the odometer! The truck runs and drives like new but I check the oil cap and the dip stick and find black chunky sluuuudge! I got some motor flush fluid to ad before changing the oil but I am a little bit scared of a negative effect. I have done this before on a 5sf-e camry engine with the same issue and same milage with no negative side effects. Anyone here experience engine failure from a flush? speak now! or forever hold your peace!

You should check out Flushing Oil Concentrate. The stuff is hella expensive($91 for a 250ml bottle), but it's probably the best product you're gonna find for flushing an engine.

When I got the 97 (218K miles) I wanted to do a flush since I didnt know its history. I bought Marvel Mystery Oil and when I dropped some of it to add the MMO it didnt look bad. After allowing to idle for about ten minutes and then dropping the oil was BLACK. It idles perfect not that it didnt prior but also seems to be more responsive and run cooler....
Good luck

if you wanna go cheap put some diesel in the engine and run it for 5-10 minutes then drain your oil... works like a charm plus its cheap then the over priced stuff ATF works great aswell lots of detergeants in atf to clean allthe junk out...

I've used some clear motor flush stuff, we charged people $10 on top of an oil change and just let it run for 10 minutes and it always seems to have helped, doesnt remove the residue on cap but it does on the dipstick (not that thats any indicator, but it looks good to the customer lol)

I usually just add a quart of ATF to the oil run it for no more than 5 minutes at idle then drain. let it drain good though like maybe a 1/2 - 1 hour.

Did you pull the valve cover to see if there is actually any sludge build up ?, some times moisture and crap build up on the inside of the oil filler cap, so that`s no indacation of what`s in the engine.

Surprised nobody mentioned Auto-RX. Check out some posts on bobistheoilguy.com or go to the website. Stuff worked great in my truck. Valve-train was clean as new after using a cycle of this stuff.

ya, 10 minutes at a idle is about all you need, just like he said about a quart will do the trick...
if you are worried about this borrow your neighbors lawn mower and try it out.. now dont go putting a quart of diesel in a 5hp lawn mower when i only take about 20oz of oil.. to start..
