Trouble with synth is that it will find leaks that dino oil wont. So while you might think it will help buildup, some may actually sneak past the turbo's seals. I dont think I'd worry much about it.

I see y'all dont have the 2' "torque tube running across the engine. Too bad, since pulling it is a snap to inspect the innards.


Engine Brite by Gunk and a wanda wash /power sprayer. No big cleaning project. Shot mine with Seymour's Stainelss Steel paint to keep it purdy long run. ( looks like cast alum with a softer "patina")
