I read it. It was about 2,5 years ago? I am very interested now too. Mmm no "search"

Not sure if this is what you are thinking of. It's something I bookmarked ages ago.

Hi Alan thats basically what I was after - thanks great help

Hi Norman, i've been at that today, unscrewed the 4 screws that hold on
the electrical connector, now thats half off i can't get it back in.
So obviously, that top has to come off. I've left mine for now, because i didnt want to force it, maybe i should not of touched it, or tried to
take the tops off first.

This is turning into something to take my mind off my steering wheel, photos to follow soon

The top is just stuck on with sealant, gently prise it off and it will come. It won't help get the plug and cables back in though as these are all external to the alluminium shell.

Had a good go at my spare one the other week

Got the top off today, and re fitted the electrical connector. Didn't look
like it needed a clean, so used clear sealant top fix top back on, think i'll
just refit them and leave alone.

I'll leave mine - my cunning plan was to strip them, get them bead blasted for max bling reassemble and add to my glowing (not) engine bay

[johnnywgk]

talking of bling, the inside of the air flow meters are the cleanest, bling
part of my car, shame i could not make the casings out of glass.

Norman if you want them bead blasting block up all orifices with silicon sealant and bits of metal / plastic for the large areas (in/out).
The beads just bounce off the sealant - thats why its important to get parts clean before blasting - similarly oil just absorbs the bead impact as well as contaminating the blast media.

I'll blast them for nowt if you want them doing (I've got glass beads aswell as abrasive media).

If they are a bit rough it works well if you grit blast them first then bead blast (though changing the media is a PITA).

Hi Chris

Will gaffer tape protect things like the electrical connectors?

[Barkychoc]

Yes that would be fine - the gritblasting isn't really that powerful unless you point the nozzle straight at it - so provided the electrical connections don't provide a route inside the unit for the grit / dust personally I wouldn't bother taping them up.

Its a surprising process in some ways - rust on steel it blasts straight off in an instant - any greasy residue hardly gets touched as it absorbs the energy.
You can hold items with rubber gloves and the grit doesn't affect the gloves at all, but again it strips any hard coatings straight off.
