Re: [T3] can anyone diagnose this noise? Old Masters chime in...


Phil said,

When running, there is a slurping sound in the case,
like sucking through a straw at the bottom of a glass.

---------------------------------------------------------

I have not had a VW for a long time to see any 
problems like this, only 2 years but I have 
had a relative experience the same sucking slurping
gurguling monster inside sound before.
Same as yours I think and it was louder when 
opening the oil filler cap. The problem was inside,
appearently the oil pickup tube was not secured to the 
oil pump passage tightly. This was overlooked when 
engine was assembled, no locktite and screws hand
tightened. The sucking sound came when the pump 
attempts to suck oil and air gets in for that
unattractive sucking sound.

Your oil pickup tube must not be secured well
enough to make a good seal or case cracked around the
input pipe or the oil pump is doing some air
sucking itself.

This is just an idea to look at.
