Or current owner, in  my case! This brings up a question. Months ago I reported
a coolant leak I could not see that AlumaSeal stopped. (It was behind the iner
timing belt cover and pump bracket). It occurred immediately after I put new
rings in (R & R of the head). I figured I got a little crud under the head
gasket. When removing all components to put on the new motor, I found the leak.
The block was cracked right through the right front head bolt hole (obviously
my doing). When I replaced the head, the bolts were hell to torque. They were
binding like crazy. I did take the time to case the threads w/ the old bolts
and used WD-40 and sucked all the crud out, but I guess It was not good enough.
This is a TD block. Question: can the crack be repaired by welding, or should I
just trash it? To be rebuilt, the block needs a bore to the oversize, and it
still may be out of spec. The ridge is huge in the cylinders. See the attached
pic of the crack before I got the head off.
