[Vwdiesel] Cleaning threads for head bolts

[mikitka]

You can make a tap out of an old head bolt by cutting grooves length wise in
the bolt. A place for the shavings and dirt to go. I purchased a tap for
mine but I was able to get it local and for a good price but an old bolt
works well. 
As for lube I used antiseise on mine, just a light coating to provide a
little protection.

I'm doing a partial rebuild of the 1.6na for my caddy project. I already
replaced the rings and started the reassembly process. I have the head
cleaned up and ready for the install with the new head gasket. I want to
make sure that the bolt holes in the block are cleaned out but I don't have
a tap to chase the threads. I have compressed air but was curious if I
absolutely need to get the correct tap to ensure the threads are clean. I
thought a heard you could make a tap-like tool from an old head bolt. Is
this true and if so is it just a matter of cutting a few grooves in the
threads of the old headbolt?

Also when installing the new headbolts, are they supposed to install dry(no
lube)?

Thanks in Advance
