What happens when cleaning the head goes horribly wrong
Some here may have read what happened to me when I tried the 'dip a vacuum hose in some water and feed it into the intake to clean the combustion chambers' trick a couple of weeks back.....
Well... the replacement of the engine is progressing well, and I will look to rebuild the old damaged motor at some point, but first - here's the damage that occurred.....
This is a straight conrod (cyl 4):
This is a bent one (cyl 1)
Messy huh???
This is the intake side - you can see how it cleaned things up, but also how the little bit of residual standing water in the head around the valves is causing some surface rust:
cyl 4 -
and cyl 1 -
However, every dark cloud has a silver (polished?) lining. Replacing the motor gives me an opportunity to finish the job of making it all look good.....
More pics will follow as I progress (including the full tear down of the old engine.....

I know about the laws of physics - I did when I tried this trick too.....
If you do a look through the Greddy thread for a post on 'taking the head off', you'll see how this all got so out of shape, and how a little bit iof mis-(missing) information can do lots of damage.
Mazda specialised part of not - I'm not keen on the thought of doing this myself ever again. My Mazda workshop can do it, and when/if they get it wrong, they can do the bloody rebuild instead of me.....
