Subject: altenator light
i currently purchased an 82 california emmission aircooled (rebuilt 40k
1.9)westy with a few bugs that i am currently working out. one that really
has me stumped is the altenator light. this light will go on with every
start up and go off when i give it a little gas. maybe a diode gone bad?
Completely normal VW alternator operator. Energizer wire doesn't trigger
until circa 1,200 rpm.
in addition, the light will go on at high rpm when i need to shift into
another gear. once i do shift up the light will go off. i tried
tightenting the belt with no avail. anybody got any clues as to what is
going on.
(PURELY A GUESS) your light performs exactly the same way a shift light
does in other VW's of that era. Check your owners manual to make sure your
alt light doesn't do double duty as a shift light. And make sure you
haven't overtightened that belt, as this will cost you your alt bearings.
also i have a very loud clacking noise (like lashing valves)
which seems to be coming from the fan.
Doubtful. Check the fan mounting bolts, and try pulling on the fan to make
sure it is tight on the crank. They *can* come loose, but (IME) one of the
bolts will come out and ruin the fan in the process.
i first thought that it was the
valves but after popping off the valve cover and feeling the valves were
tight i started to look in other directions.
Not a sure test. Reset the valve lash per Bentley or Haynes, but only use
1/2 to 1 turn after contact rather than 2 turns.
would the lifters or cam
follower make such noises, if so would a compression test reveal problems,
i
did a test and compression was 125 all around.
Test could point to symptoms. 125 sounds a tad low, which could indicate
the lash is wrong. Or it could indicate that the oil was cold, or the
throttle plate wasn't wide open. 125 isn't bad, but 140 is what I would
expect on a 40k motor. Did you reset the lash before the test or no?
i am very confused. the
noise is most pronounced at idle, when throttling it does increase at a
faster rate then seems to disappear.
Sounds like either valves or *maybe* an upper rod bearing. But I would lean
heavily toward valves. Sounds like a lifter or two pumping up after
sitting. Run a can of Marvel Mystery oil through it for a week then drain
the oil and put in the proper weight and a Knecht or Mann filter and see if
it doesn't stop.
finally, i am wondering about lazy oil
pressure. when i had the valve cover off i ran the engine and noticed that
oil was coming out of the push rods very lazily if you will, oil pressure
light never comes on except at intial test. is this common or am i just
paranoid?
The latter.
i thought oil would be spewing out like crazy.
See above. Oil doesn't really spew in the upper end. If the motor (and oil)
are really hot, and you are running at high speeds, you would see some
crazy spewage.
