i dont know if soot is bad or not in an engine. but the oil in the intake is turbo related. as the turbo went bad, it started shooting oil through your intercooler tubes. thats what would have caused the oil in your intake. it isnt very likely for a heavy mechanical failure to cause that

Ok good. Kinda scared the s**t out of me when I saw that in there. But i'm sure any kind of gritty stuff going into the motor is not good for it. I'll just have to make sure to get it all cleaned out somehow before it goes back together.

just make sure and clean it all good when the head is off of it and put all new gaskets and a new turbo on it and you should be good

Doing what ever I can to maximize the power and economy in the truck. I don't want to start to hurt the mileage, not going to tow a whole lot and not big loads either, and I do a lot of city driving.

again you gotta go to an extent of your mods, are you going to start doing pump mods and injectors and fuel pin etc etc etc. your just going to do some simple mods an hx35 would be ok, if your going higher than that look into an hx40 or an s300.

Maybe some mild injectors just to smooth it out more than the stock ones. I have an m&h #4 fuel pin, spring, thinking of the afc spacer instead of the bump (would like to keep that grunt) a strait pipe exhaust, cold air intake, throw in a shift kit and new converter, just some things to optimize the motor but not crazy.

an hx35 would probably suit you well. but that depends on your budget, if you can afford 1000 bucks plus for a new turbo get a nice turbo like a built s300 or super hx40. if you want to stay on a budget an hx35 should be fine

Well i have a spring and m&h #4 pin, want to do the afc spacer, upgrade turbo, strait pipe (maybe stacks), injector upgrade but small to get a little more fire and smooth it out, cold air intake, shift kit, conv., just to optimize not crazy power.
