Subject: [tcb] Re: Bus engines woes for a Saturday
Guess what.. I went on my little 20 mile
"deer run" as I call it and stopped about 1/2 as my Berg dipstick was flicking
on at 45 mph.... so I go back to the engine and I notice the air hose
coming from the back of the engine to the oil bath nozzle was disconnect.. (
might be a reason it's running hot letting the hot air into the engine
compartment) connected it then I notice that the vacuum connection the top left
of the pict 34 coming from the diaphragm of the SVDA was not connected, so I
connected it... Got in the bus , cranked it up and drove.
The hesitation came back just like before I changed
the plugs. Stopped the bus went to the back and disconnected that hose coming
from the diaphragm on the SVDA, guess what , drove fine (as in not jerking,
hesitation ) when shifting from one gear to the next. Drove a ways disconnected
and same thing (jerking and missing like at the higher rpm's in the gears).....
Did this switch about 4 times to make sure...... now the fun
part!
Stopped the bus to disconnect the hose (final
experiment to get back home) got back the bus, turned the key, nothing, no
noise, got lights and radio , gauge lights all light up, not even a murmur from
the starter or solenoid. I do have a hard start relay in it and I checked
the fuse and it was blown.. no 15 amp fuse in the bus.... bummer
out in the middle of no where (close to where I got
stuck trying to chase hogs in the other bus)....
Finally a guy came by, pushed me off, got home ,
(forget the cell phone too) apologized to the wife... went out to the bus ,
stuck a 30 amp fuse in the hard start relay,,,, nada... nothing.. fuse didn't
blow either.... no start....
2 problems:
Why does the bus run like crap with the vacuum
connected and run ok with it not connected.,... a bad vacuum can? (not doing
it's job? maybe) bad SVDA
Electrical (blew the hard start relay somehow or a
ground came loose) I do know if the hard start was blown if the started would
turn over. Anyone know. Thinking that the hard start blew along with the fuse
and power is not getting to the started....
I need a beer.....

Trey: Spark plugs are critical on the VW engine.
About 9,000-10,000 miles on a set and that's about it. I change my
plugs, points and condenser every 10,000. If you have a VW engine
"cutting out" i.e., missing at higher rpm on acceleration the first suspect
should be the plugs. That's not necessarily always the problem, but is
the most probable.

Sammie,
Keeping my fingers crossed. I changed the plugs
(NGK) and gapped them to .026. Drove thru the neighborhood and so far so
good. No jerking when shifting from 2nd to 3rd and 3rd to 4th. trying to
talk the wife into going for a ride but looks like we will tomorrow.
I owe you a beverage of your choice next time I
see you.
Thanks,
Trey

Sounds to me like the plugs could be cutting out.
That's the first thing I would do; change the spark
plugs.

Right before you shift from 2nd to 3rd and
3rd to 4th, the bus jerks at the end of the rpm spectrum. I don't have a
tach in it but at around 25 mph (in 2nd) the bus jerks then I shift to
3rd it's ok until I get ready at 35 to 40 mph shift to 4th, same thing
happens, bus jerks , pulsates....
The other day on the highway it started
doing this at 55 mph in 4th.... Freaked me out. I've changed the coil,
spark plug wires twice and still same symptoms. Running an SVDA with a
compufire it in, could the compufire be going out? I think these things
will just fail.
I'm sure everyone is out in their buses
today enjoying beautiful weather,
I'm trying to get ready for Spicewood.
any suggestions please let me know. I did
take the pict 34 off a few weeks ago and cleaned it up, blew out all the
jets and all that..Plus took the fuel pump and cleaned the screen and
installed a new fuel filter.
