[Vwdiesel] More Dasher?

[William J Toensing]

I have one '81 Rabbit & one '80 Dasher, both diesels, with supposedly good engines & the block may be good on the other '81 diesel Rabbit. So I will pull the head  & try tapping the head for the 1/2" grade 8 bolts I have, unless I can find where the block is cracked. Where should I look? Don't think I would loose anything other than a head gasket & time. The head is still on. Should I torque up the other bolts to specs & run a pressure test or could the block be cracked where the water doesn't leak?
Loren, thanks very much for your comments.
