[Vwdiesel] Injector -- nozzles -- ( to change or not ? )

[H.Hagar]

I know some of you are lurking for the answer.  When I first hit that problem
Loren explained that new nozzles were cheap ---install new ones.

After several years of experimenting with old nozzles  I can now say he is right.

Cleaning and testing and lapping in old ones is time-consuming . (but lots of fun)
Cleaning the nozzles I do as follows. :  Very strong TSP solution and boil on stove.

It is easy to change nozzles on the Bosch injectors ---so go for it.  I have all the tools
here so for me to test an injector takes about 60 seconds.  So why do I go for new nozzles ????
because the pressure was so much simpler to adjust.And I now know how many miles
on the little beauties. If you look at the old pintles , they may look clean to the naked eye
but still have a shiny deposit --only word I can find is ---they are glazed with a microscopic
substance.
If you have an older VW with little history ---it lacks power ?  it smokes ?  go for four new
nozzles and a Hillbilly tune-up.   Then write me a thank you note. Yes you are going to be that
impressed.    I found that I could not tell any difference between nozzles available.
Here is a little specific information.    1.5L NA   nozzle  0434-250-063 .   cost here ? 14.30CD
1.6L NA and 1.6 Turbo      0434-250-103 cost here ?  18.60 CD.    3 types of nozzles are
available here   find number on nozzle    193     293    273    for some crazy reason  the 273 cost
59.00 CD. beats me why.
A nice spring day is around the corner ---so if your rabbit -- needs a tune-up ?   why not ? the summers
driving will be a real pleasure.-- Let me tell you thats exactly what happened here last year..
Note: for a Hillbilly tune ---you need special tools (make your own) .Nice winter project.

Hagar.
