Location of the Crankcase?

For a 4.0 l6, about to get it cleaned out.

The oil pan?

Is this about sludge?

Be careful if it is.

Just some light sludge nothing to worry about, but would rather clean it out now before it gets worse.

If it's light, I would clean by doing frequent oil changes. Lots of damage can occur by chipping away. If the oil pressure is ok and the engine is running well, I wouldn't be too concerned.

I agree with @Chrisnvegas . Chipping away at sludge can create particles that clog the oil pump pick up screen and starve the engine for oil. Frequent oil changes will help but throw a half a quart of ATF in your oil about 500 miles or so before you change your oil.

Not really clear from your post though where your sludge is and how you are cleaning it.

If you cannot fix it with a hammer then it has to be an electrical problem.

Stirring up dirt in an oil system is never a good idea.

How do you know youíve got sludge in the crankcase without removing it? the crankcase I mean. If itís off then itís a simple matter to clean, if itís still on the vehicle then you can flush it. But normal oil changing is more than sufficient to keep it clean, thatís what the oil filter is for.
