My bad!!! I did apologize for my ignorance - I too checked the magnaflux site
before I had replied -- unfortunately I hadn't taken the time to actually read
the stuff on the page -- oops...



It still is important to crack check the case and heads -- normally I just send
the stuff out to the machine shop -- have them deal with it --



around 30+ years ago -- 1970s I worked at the local VW machine shop >V-Dubbs
Machine< 5 solid years as a builder. Back-in-the-day I could do 4 long blocks a
day! I do know what it is that I am talking about -- cept some of the time I
forget stuff!



I really feel bad that I may have given inappropriate information to some one in
this group and once again I apologize for my ignorance - won't happen again!!!!



....and Jim, I appreciate your well thought out reply/criticism.....

up yours

.....please don't try to **** with someone that actually knows you are full of

did I **** with you?
......And I apologize, okay, you happy NOW????!

So tell me -- no need to chastise me -- I made a simple mistake -- is not that
big of a deal -- I feel bad enough -- do you honestly think I meant to give
inaccurate info?-- no, was truly not my intension!!!

I am very, very sorry! I feel awful. So bad in fact that I won't be posting here
again -- not for a while anyways!

Bridgeport/Fairfield -- That place is on the way to the cape, so I can
easily 'sell' the 2 hr drive to my wife Thanks!
I have to crack the case still so am just getting my ducks in a row.

Would this place also do other machining related to VWs? (like valve
job).

you and I *both* know it says NO SUCH THING on the *can* of dye
penetrant...as i explained "magnafluxing" as it has come to be known is a
magnetic particle inspection...you are not gonna get that in a can...

so tell you? no need to chastise you? i gave you the same reply you gave
to a very knowledgeable and trusted regular on this board....i even used
your quoted words...so if it was condescending in any way, then please don't
cry foul, they were the same words you threw out to someone else....what is
the old saying about "if you can't take the heat"?

> I am very, very sorry! I feel awful. So bad in fact that I won't be

don't run off because you were called out....learn from it(although you
already supposedly KNOW because you do it all the time, running a shop for
25 years and all)

if you want me to i can snap a pic of the back of the can....where you will
not find those words either....you did look at the link i posted didn't you?
of course you did, that is why you had no reply to it...

Just watch out for the Statie at exit 5.

I'm sure they would, but call first to make sure
they still work on ACVWs.
