yes i dont think the intake path will be nice and clean like i want, but what really got me thinking about how bad this would be is when i did knock sensors on my (completely stock) 5.3 IT WAS GROSS IN THERE. i scrapped out so much black crap from the black plastic intake manifold and thought to myself how did this thing ever breathe like this? also waynes woodgas setups use a hay filter because the deposits that can form are sticky. the woodgas guys say the test between tar and soot is to put it between your fingers and rub it around. the tar will become sticky and hot between your fingers and you know this will kill your valves and even stick your throttle plates. i tired the same thing with the intake deposits on my chevy, never got exactly the same feeling as the tree sap substance they talk about, more like a harder somewhat cooked grease. it still seemed like it wasnt sticky but more like a dirty black butter or something lol
but on my chevy, just an egr and fuel injection and it was full of black carbon. so what i have yet to really figure out is this: the deposits formed from vaporizing oils, are those deposits as bad as woodgas deposits capable of being sticky friction increasing tars? or are they just going to be there and not really hurt anything but flow like in my chevy? i dont know but i will find out. im going to be using some method of heating the intake charge, air and fuel will get very hot, then go into the engine. it might be like my chevy where every 100,000 miles or so everything needs a good clean.
so i do expect deposits to form, if its a big or little issue i do not know yet. before the engine gets ruined its easy to pick up on the signs of the nature of those deposits though. by inspecting and testing the deposits you can change things before they cause damage.
