Thick black sut from exhaust

Recommended Posts

hi guys, im running a ts4n with a fantom fr15 engine. just taken it to the local car park for a spin and the left side of the car is covered in thick black oily sut after about 20 mins. the engine seems well in tune ie; there is no excessive smoke or unspent nitro coming from the exhaust and the throttle responce is good low and high. also 2cnd gear doesnt seem to be engaging but im not sure if that is related, i think that may just be the adjustment screw. But if anyone could explain this sut or let me know if its normal it would be greatley appreiciated. thanx in advance.

IMO carparks are covered with tyre dust from the tight maneuvering. It's most likely that that's sticking to the oil traces from the exhaust making it look sooty

Yes...if there is black stuff sticking to the shell then it is unlikely it is coming out of the engine. The oil coming out of the engine will provide something for the black stuff to stick too........
