Pulled up and parked in my driveway and noticed a serious water leak. I
would describe it as able to fill a water glass in about three minutes.
I had done some repairs to the heater line under the manifold so I
thought right away that I hadn't done a good enough job. The repair
involved removing a piece of pipe (a small bracket fell off due to a
spot weld failing and leaving about a 1/8" hole in the pipe) and
replacing it with a piece of heater hose. See picture of pipe below.
Again..., I saw this leak and panicked. However, when I reached around
behind the head where the pipe comes out it was dry as was the area
under the manifold. When I put it up on jack stands and crawled
underneath it looked clearly like the water was coming out from between
the trans housing and the back of the motor. OK, got to be a freeze
I had planned to have a pal with a trans shop freshen the trans so I
just figured we'd replace do the freeze plugs then. Got the trans out
and the freeze plugs are fine. Inspecting the heater pipe from the good
vantage point of having the trans out we could see no problems.
Put the freshened trans back in and now it doesn't leak. Given it a
pretty good test drive (passing gear etc.) and still no leak.
Any wild guesses or shared experience would be appreciated as I'm afraid
to drive too far and reluctant to sell less the leak show up again.
Here's the pipe before cutting and the piece I cut off and replaced with
