[Vwdiesel] New Diesel Guy With a Problem

Yea, like I did. I used an old head bolt to chase the
threads and sucked all the crud out w/ a soda straw
duct taped vacuum cleaner hose. And I still cracked
the block through a bolt hole the second time I
installed the head onb the old motor.

Use a tap to chase the threads! Is a bottoming tap
needed?
