Yep, dont clean it unless rebuilding the entire motor. Last thing you want is that sludge to clog the smaller oil ports in the block, head and valvetrain. Leave it alone and just change the oil frequently as in every 1000 miles or so and it will go away slowly.

Happened to us too... head was full of sludge. We removed all sluge we have been able by hands (no oil flush, cleaner, brush, etc.!). Same with oil pan. Then 3x oil change. Works well.

This is one of the reasons why I always suggest people to run full syntethic Motul along with either OEM or K&N filter to keep on the budget while reliable.

This is how my B13's head looked like when pulled apart after it overheated a few years back. I actually do oil changes every 3000miles and this is how all my heads looked like.

As mentioned above, I'd definitely leave it as it is and run Motul Xcess 5w40 or even 10w30, doing an oil change every 1000-1500miles and in about 3 changes you will get rid of must of the sludge (if not completly) under the valve cover. You could also pull the oil pan out and fully wash it before adding new oil.

I change my oil every 3k also. and use Mobil 1 5w-40. Mine stays very clean inside also.

@unijabnx2000 Do you use Mobil 1 din oil, semi-sythetic blend or full synthetic blend?
2013-07-14 20:54:45
Full syn - turbo diesel label @Kyle
Using it over 5 years now.

Diesel oil works on our engines too?
