Anyone ever tried one of the 'Gunk' engine flushes before an oil change? How did it work? I think I'm going to do it this afternoon.

change your oil more often and clean it that way. In etreme cases of sludge build up I have run ATF 1 qt in a vehicle for about 20 minutes drained and put the customer on more frequent oil changes until it clears up.

I've used seafoam through the TB before and it works great. Maybe I'll stick with what I know works...

I've only had it since march... I've done changes every 3k mi, I think it just needs an enema. Base on how much **** was wrong with it when I got it I doubt he did regular oil changes. I've heard of guys doing the flushes and having so much crap in the motor that the old oil came out like curled milk??

Another old trick is to use about a quart of diesel fuel.

Ive heard people say that cleaning a heavily sludged engine should be done slowly to reduce the chance of a chunk blocking an oil passage. To me it makes sense, i mean that sludge took time to build up, you should carefully remove it. I was gonna go with seafoam and hope for miracles, instead i just bought a case of filters and a few boxes of rotella, ill be changing my filter every 1000 and my oil every 2. Maybe in a few months ill crack it back open and see how it looks.

I did the flush with my oil change. After I did the treatment and drained the old oil I dropped the oil pan and cleaned it. Holy crap. A lot of filth. Just about all of it came out with the old oil but there was some in the bottom of the pan. The old oil came out black. I don't mean old oil is dirty looking like normal, I mean BLACK. It was worth the five bucks. I did seafoam through the brake booster and the other half in the crank case for good measure. Noticeable difference.

Good call on dropping and cleaning the pan out.

Ha, Yeah I would take credit for that good thinking but that's what it said to do on the bottle.
