I believe the some dial torque wrenches use a beam inside to feed back the torque value to the dial. They are typically good to 2%.. Typically the click type is only good to 4%.
use what you want,i know mine are dead nuts (i get mine calibrated every year)
Well I built a tester that uses a digital valve spring tester. Tested all the TQ wrenches and they all read within a couple percent of each other. I use click type because I'm lazy but they tend to vary a little measurement to measurement on the same wrench. The deflecting beam was right on and more consistent.
The MLS gaskets won't work well with cylinders / crankcase that aren't flat. Also you can induce leakage by overheating the motor. With the oil being black, it sounds like too much timing and to much fuel to offset the ping. Who tuned the motor?
I have the TTS Mastertuner. I did data runs myself. The black oil was burn off heat gasket leak at the oil dowel.

OK, so the stuff on the head you said was black and sooty was on the cylinder head and not the actual engine oil tho it will have some in it. Still overheating from too much timing could be an issue.

pretty neat little gadget,ill still stick with my click type t wrenches
I, too, prefer the click type. Mainly because its faster and you have to look at the dial. I had a fancy dial type Snap On years ago. Found that it was way too slow and a PITA using on 3 cylinder Kawasaki's when decarboning the heads.
