I am highly suspicious of those... No markings on the "packaging" to speak of, and just a paper wrapper? The coatings on the stems appear unevenly applied, like they have been sprayed with something to hide possible wear on the contact areas. I don't know if these are used or new, but the uneven coating is a major problem for me. None of the actually-new valves I have seen have looked like that.
The tips of the stems (where the rocker sits) also is different. Ours are flat with only the barest nip of the corner, these look practically tapered at the top. That may not affect performance, but then again it might.
Does any one know of a valve manufacturer in Italy?
If you look at the base around where the valve seals against the seat, it looks like new as its upstanding a little from the valve body.
The top of the stem has the angled edge like many other valves.
The weld area is definitely undercut a little.
Maybe the Turks have upgraded their valve manufacturing process & this is the result.
I wonder who is manufacturing the valves for the Chinese LDV that uses a variant of this engine?
Are the valves different on the replacement (KK CRD) engine?
