prothe??????

In some perverse way I would too..   I suppose just because they are made by the same company doesn;t mean they are made to the same specs and standards..  But then again for the cost to adjust production for several different brands could say otherwise...

Sears tires used to be a good example of this..   Sears woudl be selling Michelin tires hella cheap over everyone else..   However if you looked closely at the sidewalls it would read "Manufactured By Michelin for Sears"  There were most definitely quality differences between the genuine article and the manufactured for ___ by ___..  This ended about 15 years ago when it finally became un compeditive to produce a separate line just for one client...






Another one that I ran into today

On the other hand, it could be that, say, pistons that don't meet one client's specs still meet another repackager's specs, and thus you could have two ostensibly identical products with two wildly different sets of standards. You have the "real" deal, and then you have the "rejects" from that tighter-standard client.

This has been standard practice in the computer world for decades... When Intel makes a cpu to run at 3 Ghz and half of them fail at 1.9 Ghz, they mark these scrap parts as 1.8 Ghz cpu's and sell them as new. There is an entire market setup around these rejects and items returned to the manufacturer. Unless its going in an airplane, I don't expect any changes.

yea it's just like the playstation 3's cpu.  it has about 8-9 cores in it, but sometimes 1 core is bad during the process, so they lock one core on the ones that are good...  it does make sense. 

i suppose there might be different additives in the metal to increase its strength added at a certain point in the process to making a better part too.

I could write a book on this ;-) . Metallurgy is still an art and not a science. Seriously. I worked in the melt lab of Howmett - a division of the largest maker of super alloys in the world. This is the metal used in all hot sections of every jet. The stuff the doctors call Stainless Steel that makes artificial hips and such (zero steel in this stuff but it looks like SS to the laymen) Here's the deal - yes, every ingredient in a metal has a profound affect on the metal's properties. 2 of the ingredients you don't think about - dissolved oxygen and dissolved nitrogen. If it is an air melt (as opposed to a vacuum melt) then every minute it is molten, it is absorbing O2 & N2, at 2 different rates. This also affect other important ingredients like Silicon & Manganese.

Bottom line: not only are the exact % of each ingredient important, so is the process used to melt it - how long and how fast each melting step takes. My boss was worried about the introduction of other metals. We typically melted 10,000 pounds at a time. In 1985 we sold this metal at $100 per pound. If an amount of metal the size of a $0.50 coin was dropped into the 10,000 # batch - I forget the exact metal, but it was something like Thallium or tellurium, then the entire batch would be useless as a super alloy as the properties would be garbage.

Now, the alchemy part - even if the chemistry of the metal was exactly in the range for each ingredient, the mechanical properties could be out of spec (ASTM XXXX) if the process steps were not correct (heat Ni Cr mix to 2600 for 10 minutes, add Co and bring to 2675, add Si, wait 1 minute, add Mn, deslag and pour into casting within 2 minutes)

hmmm i bet getting the prothe pistons and coating the crown's might be just as good as the better alloy?

I wanted to stay clear of this, but as it keeps going I have to. I have bought parts and will buy some more from him. I will only buy things that I can't get elsewhere or aren't a critical part. I would buy a door handle, but NEVER another IP. As you can tell you get what you pay for and I understand that, but when he did my pump and didn't even put the mounting plate on the delivery side of the pump I was mildly upset. When I had contacted him it took him close to 2 weeks to even respond and then another week to get me the part and then I was more than upset as I had sent him messages here, on ebay, and his personal email. I had seen him logged on here several times posted but didn't respond to me. My other concern was how do you test a pump that can't be mounted? I have bought some stuff since, but never again a pump or something of similar importance.

I FULLY understand the cheap parts, but the thing I have experienced just about everytime I have dealt with him his service has been poor. Good luck to all who try him, I just wouldn't expect much if I were you.

I think VW already beat you to the punch on the 1.6TDI.

You probably already know that, I'm sure.

I bought a timing tools set from him, and had very good service. responded to my one email the same day and the packaged arrived 12 days from the day i ordered it. Not bad for crossing the border and being it was ordered around december 12th

I can't say I have any complaints with the man.. Obviously he is not selling high quality stuff or else he wouldn't be a favourite among many budget-arians   :P

Keep up the good work man.
