What effects can this fuel cause ?

[Moe]

Hello,
I work for a diesel engine manufacturer repair shop. We have a motorhome which appears to have been using a "Brown's" gas system. We see a lot of scale build up at the turbocharger entry and throughout the clean side of the intake system. My question is "can the residue that has built up and carried through the intake cause harm to the cylinders and or creating a polishing effect that may cause excessive crankcase pressure due to rings not seating properly. The injection of the gas enters the air filter.

Thank you,
Moe

Moe, do you have an analysis of this residue? Do you know what it is? Do you know where it is coming from? Speculation might not help that much. It could be a number of things and anything other than fuel and air going into an engine should be regarded as potentially hazardous. If it were me I'd check into the nature of this residue immediately. An engine for a motor home would not be inexpensive to repair or replace. Ordinarily burning H and O in an engine is beneficial and wouldn't cause damage unless burning too much H which would be dry without oil in the fuel mix. The BG systems I've seen do not produce that much H but maybe yours does? Does it replace a significant amount of diesel fuel? However, there could be something in the water of the fuel cell, some element being mixed in, metallic erosion/corrosion due to H embrittlement. There could be liquid water being sucked into the intake causing corrosion and/or leaving deposits. These all need to be checked out.
