My "new to me" LBZ with 68k miles never had an EGR blocker plate or PCV reroute done and upon removing the IC charge pipes for inspection, I notice oil in the intake of the turbo, IC boots, and I'm assuming IC itself...what is recommended in cleaning these out once the PCV reroute and EGR blocker plate is installed? Can I assume Seafoam to be viable or will this solvent remove the lubricity of the fuel and not remove the deposits?
