Engine sludge

[RizwanTj]

I have driven my jeep tj without a thermostat for 4 months and i opened my valve cover for leaky gasket and saw very bad sludge inside. Tried out engine flush of liqi moly but that didn’t work out.
what should I do?

And also ive replaced radiator fluid(dostilled water) several times but again after a few days it turns brown

The picture is pretty dark, put in a 195 degree thermostat.

Yup, probably best to put in a thermostat. It may have something to do with the sludge. Why are you driving around without one?

Try running 1 quart ATF with 5 quarts oil. Run it for only 50-100 miles

I use sea foam motor treatment in the oil and gas around a week or two before I change the oil. I find that it works with the sludge for the most part and the first time I used it seemed to worked Pretty well. I would recommend putting a Stant Thermostat In so your engine can run at its normal operating temperature.
