OEM Block Cleaning techniques

[mike fabish]

Does any one know how the OE's clean their blocks before assembly ? Thought someone on here knows, or knows someone who worked in the factory and saw the process firsthand.... Thanks

The cleaning system I've seen (major diesel OEM) was a purpose built, conveyer feed, high pressure, high volume, aqueous solution, with drying, cleaning machine.

I would bet that is the same for both gas or diesel to take the hands off approach to stop chemical ingestion to the workers.
And faster then a couple guys spray washing and blow drying by hand

And meaning no one is using long handle small bore brushes in the Oil GALLERIES. <-----notice the correct nomenclature!

Thanks for some first hand perspective.. I imagined an assembly line approach and was hoping someone could give us the details....

They also send high pressure lances up critical oil gallery's

And mainly a super-filtered liquid, not to push particles in the oil galleries...
What do people use on this forum to clean them?
