I'm not sure where to go with this.
This is a pic of under my valve cover, filter from my second rinse phase using AutoRX.
This is a 93 5.7 TBI Engine with < 117,000 miles now.
The engine was extremely dirty before using the AutoRX, so its clear that it has cleaned it up some. I actually scraped some of the junk out of th valve covers, started to clean the rockers with B12chemtool/Kero + did a short flush with some Kero/oil before using AutoRX.
I followed the Sludge instructions.
The under valve cover pic is from just under 2000miles into the second rinse and the filter just over.
I didn't take any pics previously, I should have though.
WARNING LARGE PICS

quote:Yeah that is correct, but I came up with just over 6,500miles 1500 clean 2000 rinse 1000 clean 2000 rinse. Well it actually says go between 2000 and 3000 miles on the second rinse.

I guess I thought that ARX would do a more thorough job... maybe there are some situations where one should run the ARX process three times. Yours might be one of them.
It's hard to imagine what your engine must have looked like before you started!

I'm sure AutoRX would eventually clean this up. Problem is I don't really drive it much. I went out of my way to get that many miles on it in a year. With the price of gas now I might never drive it, if I'm not hauling something.Maybe you might want to do a mega-dose of LC and see what happens. It acts faster than ARX... or, you might want to do that third ARX treatment, but leave it in for the clean phase for 2,000 miles and rinse for 2,500 miles.

I'd use Gunk 5-minute engine flush (a BITOG heresy), then remove & clean the oil pan & oil pump pickup screen. After the Gunk treatment, I'd run an HDEO for around 2k miles, then re-evaluate.
Holy, was that engine involved in some industrial fire? lol, sorry man, just looks bad. I agree with all of the above comments, cant go wrong with any. Try the LC flush or Amsoil/gunk flush then redo the autoRX and see what it looks like. Post back and let us know
I cleaned each rocker hole manually, got some of the major gunk off the rockers (before AutoRX). I flushed this thing with 16oz Kero (isnt that mostly whats in GUNK engine flush) before AutoRX. I shoulda used a quart or more. But it didn't aparently do squat.
Maybe a flush now would help. But who knows.
For as much money as I waisted in gasoline(extra pointless drives) +oil adds, I could've put it towards a rebuilt more powerful engine.
I was thinking the PCV valve was at fault, but the drivers side rocker cover has some sort of vent ( the one I took a pic of inside). I don't know.
I'm actually suprised this thing still runs ![[Smile]](images/icons/smile.gif)
Right now I'm running 3oz A-RX with 5Quarts Mobil Clean 5000 (Free)
Right now I'm running 3oz A-RX with 5Quarts Mobil Clean 5000 (Free)Put the LC in there and flush 'er out! That's the next action you should take with regard to this.

Forget about trying to get it clean. Use a good HDEO with 3k oil changes until the engine dies.
I had a caprice with a 305 that looked like that when i bought it at 100K. I still got 40K miles out of it and the motor never died.
