Depends how deep the Anodising was done, a few thou usually. Anodising is a process that changes the chemical structure of the outer layer of the metal. Anodising actually reduces the thickness of the metal it does not add to it. :)

So the
the thickness of
the orings and the the pressure exerted on them will have no deeming or adverse affect on the valve block what so ever :):):)

As we are talking microscopic terms :D
 
Time out lads ! wammers can you tell me the positions of the NRVs. Mine were all facing the same way ie. out of the block, but when I looked on paulp's site it shows the top one facing in and the other two facing out. This is a block I got to refurbish and has not been fitted.Ta

Paul is correct. Follow that. :)

It will if you remove the hard Anodised finish, it is there to prevent corrosion and wear. If you are asking if i would take a valve block apart and clean it by blasting. No i wouldn't, it's not needed.
 
I would not go near the valve block with any sort of sand blaster. Sticking it in the dishwasher brings it up like new if it's really bad.

Really :D

Aluminum is generally not considered dishwasher safe. It reacts with the alkalinity of home dishwasher detergent (these are alkaline to remove fat/oil.) There's a thin native oxide on bare aluminum, but it's not thick enough to be a protective layer.

Many things can cause a dishwasher to perform poorly, but the cause is likely a widespread recent change in the formulation of dishwasher detergents. If your detergent was manufactured before July 1, 2010, it may have contained more than 0.5% phosphate (so-called "high-phosphate"). If manufactured after that date, the detergent probably contains no more than 0.5% phosphate (so-called "low-phosphate"). Unfortunately, high-phosphate detergents are the only formulation that reliably produces "shiny clean" dishes when used with hard water (8-grain or higher). 8-grain hardness requires a detergent that contains at least 5% phosphate -- ten times the concentration of the low-phosphate formulation -- to work well.

Try the steam cleaner next time ;)
If your that worried

Who said anything about using detergant and the alloy is anodised? I got the dishwasher trick from Rangerovers.net, it works a treat:)

Have you seen the crud left on a plated sometimes !
I'd like to know how a dishwasher can clean all those small internals if they just about manage a plate , you could blow it out with compressed air , but if it was at a late stage and well and truly built up over time no chance

Cleaning consultants :)
That what we do clean things properly

Enjoy your dish washer lol
 
To change the subject ha ha . Ultra sound cleaned the block and rebuilt it with new O rings. Very good service from the O ring supplier that wammers recommends in his "how to". Just waiting for the new dryer to arrive. So back to the argument.:pop2::fighting2:
 
All stripped down, diaphragm ok but a little deposit on the valve seals, easily wiped off. With everything stripped off, cleaning block was not a problem.Thank you

Thought you had wiped the seats clean:) bit of a change there, can't argue with the ultra sonic method,but the industrial size ones can be a tad pricey unlike these small jewellery shop ones. 4k plus it a bit pricey to do a block :)

Not a little jewellery cleaner, think it was about £120, bought to clean some triple SU carbs off the E type. Yes I did wipe the seats but Datatec reminded me about the cleaner, It doesn't get used often very often and gets forgotten :)

4K? we are talking a valve block not a block of flats here. You can get a ultrasonic cleaner big enough for a valve block for less than £150.00.

They are only any good if the particles are loosely
Embedded !!! ,
He was able to wipe them off they are made for soiled items

Not hardened embedment

That's why you need the solvents :)
