That was the good old days.

These days, a lot of components have coatings on them, surface treatments that substantially alter the material's properties in use.

These go far beyond the old fashioned heat treatment or case hardening of metals.

You heard me mention the DLC coatings on the injectors, but there are also things like nickel phosphorus-silicon-carbide, e.g. trademarked Nikasil, Alusil and Lokasil, or a even neater process that puts on a thermally sprayed nano-coating with a Plasma Transferred Wire Arc (PTWA) process for aluminum cylinders.

Ideas being worked on include thin layers of ceramic coatings, that alter the refractory properties of metals --- currently available for limited volume race engines.

The gist is, it is no longer possible for a fella with a machine shop to make anything --- without doing the coatings or other surface treatments, some of which can only be done at the time when the part is manufactured (e.g. like carbide coatings).

Quite often, the manufacturers are quietly doing these things (often for key parts in their own in house operation), and not letting on how they have tweaked the part to stall the cloners / competitors / aftermarket from figuring it out.

That is why you don't necessarily hear about this stuff.

Sometimes, it is just "told" in terms of "manufacturer says XYZ cannot be done to this part" without an explanation.

I don't know if that is the case.... but when I hear that... I start digging.

 

Its not the case with these heads.

 

That's true with some of the stuff that I work with. In order to handle the image printing it requires coating that if not done during production it either won't take or if you use an "a/m treatment" it'll take, but won't last as long.

 

First, let me mention I thought Matty had a great post. It was very informative for those of us that are not as polished as the good techs on here.

Second,
Cheezit, could you elaborate about the parameters you mentioned in your statement concerning the sweeping of the turbo vains.

"yes It should be sweeping the vains. there are some peramaeters to meet however."

very much agree on mattys post was it well done.

there are things like temp and idle time that come in to play. i would need to go back and reread the info on the tsb for the reflash to give a better listing then that.

 

If you have the tsb# for this flash I would appreciate a post with it or a PM. I'm very interested in how this flash will affect my 6.0.

 

Here ya go:

 

npccpartsman,

Thanks for the tsb link. It helped a lot. I wouldn't be on this site if I didn't want to learn something and that is only made possible by the endless contributions made by the good folks on this site.
