Hi,
I'm so glad I found this list. My daily driver is a cummins in my 3/4t truck
so I just don't know about the vw diesels. My husband would like to get a
jetta or golf. I saw an 86 Jetta with 295k miles? It seems like a lot of
miles to me. Is it just about worn out or can it go another 100K? 200k?
Also what other types of engine troubles should we be on the lookout for
when we look at the car?
If anyone has any info or comments I'd really appreciate it.
thanks a lot,
Sharon

Since this is a real odd problem I might just build a new black box. I
really like this approach to getting a regular tach signal which allows
cruise control as well. I did draw my own circuit board using etchant to
make the board and used surplus parts. Seems odd possibility of a
malfunction due to sensor reflection becoming poor off the metal tape after
10 minutes of use but fine before that. I did paint area between sections
flat black. Cannot figure why everything ALWAYS works fine for at least
10-15 minutes from engine cold start up. As you pointed out since cruise
also malfunctions at same time probably the used jetta tach is likely not
the problem... I moved the black box to inside cabin and only mounted sensor
in engine compartment thinking maybe heat bothering some component Same
trouble...Oh well....

I have some additional troubleshooting tips on my web page if you are able to test the
circuit board once it starts acting up:
http://www.4crawler.com/Diesel/CheapTricks/Tachometer/index.shtml#PartsKitTroubleshooting
Or for the heat side of things, get a can of freeze spray at an electronics store and
chill each component in turn to see if you can restore proper operation. If so you have
found the heat sensitive part.

hi sharon,
i had an 86 jetta 1.6NA (non turbo) and it was great.
i regularly got over 1000 km's a tank. the engine was
so great that i swapped the engine into a 92 gasser
when the 86 body was finished.
the only problem i had up here in quebec (canada) is
that the body rusts out pretty fast.
i know have a 96 jetta 1.9L AAZ of which i am very
happy with and running on veggie and a 2002 tdi.
over all, the vw diesel engines are very strong and
have a very strong heritage of diesel engine
production.
regarding the jetta u r looking at because it has
higher mileage u should get at least an engine
compression test done. it should be around 450lb per
cylender but i am no pro.
asside the engine, the parts are inexpensive and
easily available.
just my 0.02$
hope this helps and keep in mind they run great on
veggie as well. i had the 1.6L and now the 1.9L
running on veggie and it greaaaaaaaaaaaaaat.

Hi Sharon;
How was that close to 300,000 miles put on the car. If it was 50
trips across the US and back it is probably just broke in. If it is 60,000 5
mile trips to the grocery store it is probably all used up. I would want to
look at maintance records to see when the normally worn out and replaced
parts were taken care of. At that mileage most likely they replaced the
timing belt more than once. How about shocks, struts, brakes, C/V joints,
alternator, vacuum pump, belts, hoses, etc, etc. Perhaps more than likely it
has had a head gasket replaced. I would think that it is likely one would
need to freshen up the engine. Rings, bearings and on the head at least lap
the valves, replace the exhaust guides and valve seals.
If the body is good and you plan to drive it another one hundred or
two hundred thousand miles rebuilding it has to be a lot cheaper than buying
a new diesel VW. I just wouldn't pay too much for the car unless there has
been a lot of recent work on the expendable parts.
I just got done resurrecting and rebuilding a 1981 diesel VW Dasher
Wagon and drove it this weekend from Chehalis WA to Twin Falls ID and back a
trip of over 1300 miles on 25.1 gallons of fuel for a nice little mileage
figure of 52.9. Now tell me how many new cars can do that.

Brian Decker, if you have been following the various comments, you know I am also reviving an '81 Dasher diesel wagon. I have got my Dasher to get back on the road but waiting for proof of insurance so I can renew my Calif. license tabs. In getting 53 MPG with your Dasher, did you poke along at 45 to 50 MPG or did you drive at the speed limit plus a little bit? Once I begin driving it, I will be checking my MPG too. Do you have the stock Dasher & stock 4 speed? I don't recall who, but someone has a Quantum diesel & 5 speed in their Dasher diesel.

I run a 1989 VW Jetta Diesel, on its 300,000 mile, and its still strong.

To:
Message-ID:
Content-Type: text/plain; charset="US-ASCII"
Hi everyone, I have been following this list for a while soaking up
information for the ongoing repairs to the number of diesels I have. The
most recent car is a 1.9l td 1994 jetta. The car is smoking bad when
under power and generally not as bad when idling but still smoking. The
engine was rebuilt approximately 20k ago according to the previous
owner. I'm thinking the turbo is causing the problem but I'm not sure.
Does anyone know of some troubleshooting checks for the turbo? I have
heard that these turbo are prone to failure with high kms. The turbo has
probably 300k on it, I'm not sure because the odometer has been reset.
The car starts great and runs smooth, the smoke is a grey colour. I have
been looking around the web for a used turbo but they seem rare. Does
anyone know where to find a turbo if indeed I need one? Thanks for the
help
Steve

I have an '86 TD with over 650,000 kms, and an '87 with 500,000 kms. Both have had a rather long, hard life, but what is going to end at least one, soon, is body rust. Not structural stuff, but every place that had a stone chip 20 years ago on the '87 is now a fist-sized hole! The '86 is rusting everywhere, bit by bit, but should be useable for a couple more years. The 87 works and is safe, but the roadside inspection nazis will get it one day.

Hey all, just wondering if what I am seeing is normal,
I have seen hints of it in past post over the years.
I set the timing perfect with pump bolts lose, just
lose enough to move pump. Here is what I am doing
1. I tighten pump bolts and turn the motor clockwise
two complete rotations and stop at TDC
2. pre-load the dial gauge
3. turn motor counter-clockwise until needle stops
moving
4. move dial gauge on shaft to set it back to zero
5. move engine clockwise back to TDC
I check again and it goes from .0395" to .0410" or
abouts. I did it like 3 times, same thing. So, the
pump is moving when I torque the 3 bolts/nuts and the
back squeeze holder bolt.
So, I need to set it below where I want it to end up,
like .0385", then when I tighten the bolts and rotate
the motor 2 times and check again it will be where I
would like it to be, between .0395" and .0400" or
between 1.003mm and 1.016mm
Am I splitting hairs here, I am sitting at .0410 or
1.041mm now, should I leave it there, run it for
1000miles and when I give my head bolts the extra 1/4
crank down, then check timing again and reset if
needed????????
Thanks, Bryan
