Guys
For those of you that saw my corvair powered KR at the gathering
and know that I tore it down the week before to repair a crack in the
block also know that I had an oil leak. I was loosing about a quart every
2 1/2 hours. I have located it. I had thought that it was leaking out of
the push rod tubes and I had done something wrong on the left side. After
cleaning it up and running for short periods on the ground i found that
it was actually leaking around the cylinder base gaskets. This is not all
that surprising to me as this is the 3rd time that the engine has been
apart and reassembled with the same steel gasket. I did use the copper
RTV sealant with them but will have to take this side back apart and
clean it up and install new base gaskets. (really only about a 3 hour
job)
On the cracked block I only have a theory and that is when
splitting the block it comes apart very hard and I was using a block of
wood and a BFH (type of hammer) to tap it apart and the top inside corner
is one of the spots that I had put the block of wood to loosen the case
up. I may have fatigued it and caused the crack to start. It did not go
through any bolt holes and did not finish cracking from one place to
another. If this did cause it the crack took about 100 hours to develop
into something noticeable.
