Getting Rid of the Sludge

[fwasilewskilak]

I was wondering if anyone has any thoughts on how to get rid of the sludge. Specifically, how do I get all the sludge out before I switch to synthetic oil? It sounds like there is a screen in the oil pan that gets clogged and drops the oil pressure. I figure this needs to be cleaned for sure. I just do not know if we need to have it inspected and manually cleaned or if you can just clean it with chemicals. Anyone know a good additive that could help solve this problem? Please tell!

Here comes that Mobil advertisement again, just wait...

Does the Mobil 1 Synthetic Oil really work or is it just some cheap advertising trick that someone is pulling. I sure as hell hope it works. I just changed my oil last night and added Mobil 1 synthetic hoping for some good news. We'll See.

That xs29l dude knows all about this stuff. Perhaps he will see your post.

i would just change your oil and filter every 1000 miles for awile before instaling any syntetic oil synthetic oil can help

2 quarts of kerosene. 3 quarts of oil (just not quaker state). run engine until warm (Don't drive the truck)

disclamer:
Kerosene is flammable. If you are reluctant to do this, then just go buy 2 cans of "Rislone engine restorer" and use both cans (ok, well it is kerosene....But anyway...). If you drive the truck, and there are oil leaks, you could burn the truck up, so don't drive it until the kerosene is drained.

This really works, where other crap and additives don't.

Change oil again. Use synthetic oil if you want; It'll help, but not as much as most people would like you to think.

Change the oil every 1000 miles or each month until it runs clear for 1000 miles, then go back to 3000 mile maintanence schedule.

And your D will live happily ever after.

This sounds like a good idea, have you used it, so how many times do I have to use it? is it like an oil change and then just let it seat and then drain it out and put the oil back in, previous owners have always used regular oil on it, and thinking on going syntetic after I clean it. I just want to make sure it is clean before I change to syntetic. So do I do this ryslane thing every couple of months or is this a one time deal. Thanks a lot for the input.

Hi,

I was talking to on of my coworkers and he mention something that called my attention abot this idea, since this have never been done on this engine (that I know) wouldnt the build up around the valves and the pistons that have been living there for a while make the engine adjust to it, and if it is adjusted to that clugging there and I clean it up wont they be all loose and start making noises and maybe even damage something,,, Im just curious, because my engine is now 92K miles old.... Thanks for the information and the help that you have provided me so far,

I called the local auto part Napa and the sell the Rislone, they have the Flush kit, and they have the one that its like a Quart of oil that you are supposed to put in with your oil changes in replacement of one of the oil quarts.. should I use the flush kit once and then do a oilchange with a quart of the rislone, and repeat the process every month untill it runs clear? Thanks again and sorry for the long questions, Im new to all this.

You can use the flush kit, but you only have to use it once. Then change the oil every 1K miles and use the rislone "quart" thing, but you don't add it as oil, you add it before the oil change and run the engine, then drain the motor oil and the flush.

After the oil stays clean (golden clear) for 1K miles, your engine will be clean enough to go back to the 3K oil changes, and no more rislone. Overuse of any oil treatments or flushes can cause troubles too. I wouldn't do it more than 4 times before I just used regular oil.

I hope this isn't to confusing to follow
But I'll expand on it if you need....

When would be a good time to strar? I think mine is aroud 68,000. Its do for a oil change. I myself have thought about the syn oils. Are they worth it? I know the cable co I used to work for Syn is all they use. They change the oil every 6,000.
I want this motor to last till the body falls off. So if this is a good thing I might try it out. I do have a extened warrenty on the motor and tranny. I dont want to put that in jepordy..

Ok, let me see if I got this,

1st - leave the current oil in, and dump the rislone Flush inside the oil compartment, run it for a few minutes in iddle.

2nd - drain all the old oil + flush liquid currently inside the engine out

3rd - put a new oil filter, and insert 4 quarts of new clean oil and one quart ofthe rislone engine treatment oil.

4th - use the vehicle normally for a month and repeat this whole process again every 30 days for a few months or untill the oil comming out is golden clear.

did I got it all right?

I read on the net a guy that after draining the oil out he removed the oil pan and checked the screen in front of the oil pan looking for sludge accumulation, and he instead found lots of carbon deposits on the screen. He said he used lots part cleaner and a wire brush and he cleaned the screen, then replaced the pan and kept flushing it till it was clean. What do you think.

Thanks again!

Cleaning the sump and changing the pan gasket would help, but you do have the procedure correct.
I wouldn't worry too much about the sump, unless there's obvious sludge in the pan.

[rod2envy]

I got a chiltons manuals and according to the instructions of removing the oil pan I have to emove the front axles,,, that is totally uncool, seens like a lot of trouble, Im going to do the flushes and use the rislone for a couple of months and see how the oil comes out, if it doesnt get any better I might have to do it..... I just didnt got one part, is it cool to run the whole month with a quart of rislone oil on the engine? or is it meant to be removed right away... Hey thanks a lot for the help, Im doing the flush today..

Ill let you know how did it go.

use the engine flush: you just run it for a little bit (warm) and then discard it(drain it). It's not the "treatment", which stays in, but It probably wouldn't hurt to use that too.
