h20 injection for cleansing purposes
h20 injection for cleansing purposes
Here's the idea:
Inject water to clean the pistons and PC's, primarily. I have this 190D that I just put a new headgasket on and the inside is a mess b/c some PO was burning all sorts of garbage straight from the tank.
I want to inject water to clean it up once its running. Not for performance on a regular basis so much as a quick mod to get the inside back to normal.
sorry, no pics... but 2 of the 4 PC's were 40% completely clogged. They have been reamed and the head is back on already.
So far, it seems I should inject a fine mist slightly above idle at operating temperature.
any other details???

A buddy of mine did it to an old 12 valve Cummins 6BT several years ago. I don't remember all of the details but he said it worked quite well. I know he used a hot water pressure washer and held it back from the intake several feet, as the source of H2O injection. He said he was amazed at all of the crap that came out of the tail pipe.

Why? Water in the oil is not overly unusual, a good high way drive will burn it all off.

Thats why MB changed the oil cooler thermostat from 95*c to 110*c, boil off moisture in the oil.

Hydrolocking isn't the concern when spraying a combustible fluid into the intake of a diesel.
