[Vwdiesel] Cracked Block?

[Val Christian]

I have a 91 Jetta 1.6, with a coolant leak in the vicinity of the water
pump and the crankshaft.  I replaced the waterpump based upon the
mileage it had been in there (175k miles), but found that the old
pump appeared to be just fine.  With everything back together,
coolant poured into the engine, comes out near the area between the
waterpump and the crankshaft.

There is no oil to coolant nor coolant to oil contamination, nor is
there any sign of burning coolant.  The head gasket seems just fine,
although I can't completely inspect the perimeter near the timing belt
area.

At the time I replaced the water pump, I elected to also replace the
timing belt.  I looked for water leaks, and found none.  However, in
retrospect, there was warpage of the lower timing belt cover.  Perhaps
where the leak may be.

Has anyone seen a block crack such as this?  Any insight or ideas to
share?


Thanks.
