288k. It's oil off of the turbo boots. I read about some mod that stops that. Can't member which one right now. Crank case vent mod I think. I'm gonna pull em off and clean em up and do that mod. This truck is most likely not going anywhere anytime soon so I got time all it will take is money(that I don't have haha). I'm hopefully gonna get all the valve covers turbo y pipe and boots cleaned up pretty soon. Gotta pull em off and do glow plugs before it gets cold out.
If I can afford to I will. I think if I clean them up with some brake cleaner then rub them down with alcohol to get any moisture off I think they will seal fine. If not guess I'll try and get some used ones or new
slap you a 00 model turbo on that thing and intercool it
id trade straight up for a mint condition idi turbo
