VG Turbocharger cleaner

[Latestarter1]

I make no secret of my distaste of VG turbocharger on Volvo D3 or for that matter any diesel engine with swing vane VG turbomachinery in marine duty cycle. Cleaning them up is a tedious and filthy job, worse still if you have tec who is a lazy numpty and just fits a reconditioned unit costing you $$$.

Walked into my local Bosch shop and they were using this on VW diesel with overboost derate issues due to gummed up turbocharger...........http://www.innotecworld.com/c-1064-turbo-clean-set.aspx. I hung around to see the results, worked like a dream!

Have been dealing with wtg turbos since 1998. Even with clean burning engines the wtg position can stuck. Mainly because the engine is operating at 100% power for hundreds of hours. Oil desposits is the main reason.

Do you think this helps only on soot?

Remember in late 90 we mixed water and diesel. Up to 20% water in diesel.

The NOx and soot numbers went down but most amasing was when opening the engine. All the soot was away. Engine soot where cleaned by water.

lOOKS REALLY INTERESTING THIS, BUT HOW DO YOU KNOW IF YOUR TURBO IS A VARIABLE VEIN? MINE IS A K26 KKK TURBO ON MERCRUISER 3.6L DIESELS

What do you clean non VV turbos with? I have two slightly grubby Holsets.

Standard turbo on most of the Merc diesels

Not a VNT FYI

The only swing vane variable geometery turbochargers you are likely to come across are Garrett units on LDA (Light Duty Automotive) engines Volvo D6, VW, etc. Others have simple turbochargers, some with waste gates.

For conventional turbochargers there is a very simple and cost effective process. Adding small amount of water through the intake of a diesel engine under medium to high loads has been around for decades and has shown that it can solve some simple issues related to excess carbon buildup and coating that may affect turbocharger performance.

Adding a small quantity of detergant solution has shown to help on the remove coating issues related to oil mist, etc, that accumulates on the aftercooler, inside air pipes etc...But, understand that the water is the big cleaner here as it turns to steam and does most of the work, adding turbowash to the intake of your engine will not solve any serious or needed aftercooler servicing that is part of what I consider required maintainence every two to three years. Spraying some turbowash (maybe 6-8 ounces of water mixed with a teaspoon of Fairey liquid) into the turbo intake of your engine at at nothing less than cruise HP level or above, (not alongside the pontoon in neutral) over a 3-5 minute period can help clean turbo blades, air pipes and aftercoolers of some excess oily buildup without having any damaging effects whatsover.

Consider a loaded truck at 56 MPH in driving rain, it consumes more water vapour with zero ill effects. For those with seriously gummed turbochargers take a look at your crankcase ventilation arrangements.
