Cleaning engine sludge out without disassembly

I've got a '47 H that I've been running non-detergent 30W in but, via the advice in one of the articles at this web site, I'm thinking about switching over to 15W-40 detergent. I haven't had the oil pan off yet and I thought I'd take this opportunity to get the sludge out. I'm imagining I'll take off the pan, clean out as much sludge from it as I can and, if possible, take off the screen and clean it up. After that I'll be cleaning whatever I can get to with solvent and then replacing the filter and filling it up with new oil. Can anyone tell me what else I should pay attention to? Is this a bad idea as it might dislodge particles that will get stuck elsewhere? Thanks for any help.

I run Marvel Mystery Oil to clean out sluge. I would run it for 1 or 2 changes it works. Then go to detergent oil. Be sure to change the filter.

I would introduce the detergent oil slowly instead of all at once. Every oil change add a few more quarts of detergent oil to it. If the tractor is running and doing fine on what you are running you may not want to change.

I would not do it if it were mine. If I took off a valve cover, well sure, I'd clean that or the oil pan if removed but spraying down crud inside the engine is just looking for trouble.

You guys are awfully certain that there will be a lot of sludge present. You may be surprised, especially if the tractor was maintained.

It could be clean inside if the thermostat was working. But if it was running cold there could be a lot of sludge in the pan from water condensation that was never cooked off.

I'd just clean out the pan and stop there, the rest of the engine will probably look surprisingly clean (mine had an inch of greasy gunk in the pan but everything else was fine).

I have had fantastic luck with SeaFoam.
Put a can in with the oil, run it hard for several hours and drain it while hot.
I have also heard of people filling the crankcase with kerosene, pull the coil wire so the tractor will not start and crank the engine till the oil pressure gauge comes up, then drain quickly.

Dave, Your going to get as many replies on that question as you would if you asked about what type of oil is the best! That said, if the tractor is running fine on 30 wt I would stick with it myself! If you want to clean the sludge out of the pan and any other areas thats fine and also another story. I have heard too many people say they had motor problems after the switch. Just my thoughts.

After the oil pan I'd also pull the valve cover (time to adjust them anyway) and the side inspection plate. With the engine "opened up" like that just start spraying it down with the carb cleaner/degreaser of choice. Let it sit overnight and then put it back togather.

years ago i bought an old chevelle with a canister oil filter,and every time i changed the oil and pulled the can it had about 1/2 inch of sludge in the bottom,so i bumped my oil changes up to 1500 miles from 2500 and after that i started getting less and less sludge til it was finally gone and then it never came back.when i started i was running valvoline and then i switched to IH low ash 30wt .i tore that engine down and the only sludge i found was on the threads of the main and head bolts.my suggestion would be to start changing it more often and make sure its hot when you dump it,you may get hot fingers doing it but you get lots more crap out.
