Coming very late into this:
 
I came up on air-cooled VWs, and have done about everything on these beasts but those things that required an hydraulic press or welding.
 
Today, I will change tires, brakes, oil, coolant, plugs, sensors, and other discrete go/no-go devices. And I have some throw-back opinions:
 
Brake fluid and coolant gets three (3) years before a flush and re-fill.
Tires get five (5) years max no matter what the state of wear.
Trans Fluid (Auto) gets 100,000 miles.
Trans Fluid (clutch) gets 40,000 - 80,000 miles depending on type.
Oil is synthetic, and gets 10,000 miles or one year, whichever comes first.
With the trans fluid, so goes the differential fluid(s).
 
Otherwise, modern tooling being what it is, my mechanic can get what I need a weekend to finish done in a couple of hours _AND_ he gives me a warranty.

I have done all except #3.
 
The worst job I consider is exhaust. I guess that has diminished these days.
 
The hardest is being a good diagnostician.

Never said you were stupid. You may be a nice guy in person but you
come across as an arrogant @#$ that knows everything and the rest of us
know nothing. We can never be as good as you.
 
A good engineer would know that even simple things like piston rings can
be improved in many ways, yet you insist they are no different than ones
made 60 years ago. Well, maybe if you think that is correct you cannot
be a real engineer.
 
I have known many engineers, have a couple in the family but none would
make that statement. I do know people like you though.
 
Any of theses your projects?

Did I say that is the only way? No, I did not. You are making up
things to suit you. You did, however, take the time to infer you know
everything about history, discovery, science, and the rest of the world.
Books are great, but seeing some things on TV can be very enjoyable
and educational for those of us that don't know everything..
 
You can watch an episode of "How It Made" and they may do a segment on
piston rings and the latest technology.

My wife pressured me for a new one last year. Bought her one, then
traded mine a month later. She's done 14k kilometres in hers, I'm up to
35k kilometres already.

True that. The indy doesn't have access to all the needed info for a
start. Nor the dealer training. They are both important.

I watch docos, etc on the internet. I prefer to schedule my own viewing.

That is the easiest providing you have a good understanding of the
underlying systems, possess a good range of diagnostic equipment and,
finally, know how to use it. For judgemental issues, know first what is
*normal*, then you can easily recognise *abnormal*.

You stop learning only when you're dead.
 
I learned a LOT in this thread, particularly about WHY engines last
forever, and why exhausts last forever, and why bearings last forever, and
why ball joints last forever.
 
That's all good.
 
I didn't learn a thing on rings that I didn't already know though. :)
 
I'm all prepared to learn how the metallurgy or shape of rings is different
nowadays versus yesteryear, but I haven't seen any reference that shows
even the slightest improvement over the years.
 
It might be there, but saying it's there isn't the same as it being there.
Proof in logic is always very simple.

If you think FWD is all about handling, then "your" logic should have a ton
of references to back it up.
 
If you think slotted rotors make any real difference on the street, then
you should be able to find a ton of reference that proves that (and not
some EBC marketing bullshit).
 
If you think rotors warp in street use then you should be able to find a
ton of references to back up your logic.
 
On any topic you see me take a stand on, it's not "my" logic but the logic
that has tons of references that back it up. Witness the fact that I gave
you a ton of references on rotor warp.
 
Now I understand that people don't think things through, so I understand
the 20-year-old kid who thinks FWD is all about handling because he falls
for the marketing bullshit. I understand all that.
 
But if you're over 70, you should have figured out that marketing is almost
all bullshit and very little logic by now.
 
You're not a young kid anymore.
Logic has to show up sometime in your life. It just has to.

I don't know everything and I actually don't know much but I use logic on
it all and I've been on car forums for decades, where there always young
kids who fall for the marketing bullshit every time.
 
Not only do they fall for the marketing bullshit about FWD, rotor warp,
drilled rotors, pad friction, and so on, but they also desperately want to
BELIEVE the marketing that their car is special.
 
I can't count the number of "red" coolant "blue" coolant threads there are
from kids on Toyota and BMW forums respectively who want to desperately
feel that their engines are somehow special and therefore they require
special fluids (when water works as well).
 
These are all age-old arguments along the lines of "what oil" that I'm just
sick of. So it shows here and I get cranky, especially last night.

You completely whoooshed on what I said, which is that I'll believe
anything if someone proves it. Anything. I believe in gravitons for
heaven's sake, and string theory, and that spacetime is warped by mass.
 
I'll believe anything if someone has a logical argument for it. But if
their "logical" argument is that Detroit came out with FWD for handling
reasons, not only is that illogical by failing every logical argument known
to mankind, but it's nothing new. It's the same crap the 18 year old kids
spew on the car forums.
 
It's the lack of logic I decry.
 
The whole brake warp idiocy suffers from the same complete lack of logic.
So does the drilled versus solid rotors.
 
If people actually followed their own logic, they'd be forced to undertand,
but they don't.
 
Take octane ratings for example, which we haven't covered. Do you know how
many times I've heard morons tell me that there is a lot of octane in
gasoline? Do you want to know how many times I hear people say they put the
high-test into an engine that isn't spec'd for resistance to knocking and
they declare they get better performance and mpg?
 
Morons all follow their own convoluted logic but it always stops short of
finding a reference that backs them up.
 
That's why here, I kept asking for reference, which I *knew* would never
exist because I could logically see the fallacy that they emotionally
cannot.
 
Mind you I don't take names. I just don't. If a post says something stupid
and it happens to be from my mother, I'll call the post out for it. And if
the post says something intelligent and I happened to have reamed that
person five minutes prior for idiocy, I'll thank them and congratulate
them.

You *should* know people like me.
We're called logical people.
 
We don't believe only in Marketing Bullshit.
I *hope* you know people like me.
 
Dear God. I hope.

I disagree but I understand why you say that.
 
You would presume that the dealer knows the most about the car.
That hasn't been my experience.
 
The parts guys are horrendously bad and the service guys marginally better.
 
I don't think it stems from ignorance as much as not caring.
 
This is mostly Toyota and BMW I'm talking though, so maybe your dealer is a
different brand.

You do know that only 2 of the three bulbs should be lit for a good
outlet, right? The ones going from hot to ground and hot to neutral
should be on. The one going from neutral to ground is always off
unless hot and neutral have been swapped due to a wiring mistake.

Yes. Like this:

The neutral line lights only when there are swaps, and only in two of five conditions.

Hi Pat,
 
I am aware that only two of the three bulbs are supposed to light under
normal circumstances. The hot to ground light is not working which is giving
the false indication that the ground is open when in fact the ground is in
good condition.
 
Thanks for your reply.

Yes, that replacement will work fine. So will almost any neon lamp that
physically fits. Your cost, after shipping, will be a little more than the
cost of a new checker plug...
 
These lamps can fail because of slow gas leakage, so if the other two
seem dim, or flicker, it might be prudent to swap them out as well.

Someone in this group mentioned a while back that if you send a check or
cash and prepay your order to Digi-Key, you get free shipping no matter how
small your order. That helps out when you only need a few parts.
 
Thanks for your reply.

Modern units seem to use more complex circuits where all 3 normally light.
