Has anyone got any guides to correctly and safely cure the sticky vanes and clogged up turbos on the PD170. I have developed overboost issues due to the vanes sticking, a very told me to spray Mr.Muscle over cleaner into the turbo which will clean it up. Anyone got any advice, help or guides cheers. Ps- I'm to low on funds at the mo to have a turbo recon but I will be looking at that in the future. Cheers guys.
