Blog revival - Interesting Exhaust Manifolds...?

Blog revival.

We've been far too lazy over the last few years and haven't updated this thing, so i've challenged myself to write a post each week until we're up to date. Here, in no particular order are some of the comings and goings of Trevor:

I've had a new engine fitted, and upon dismantling the old one, found this interesting exhaust manifold failure that was surely going to lead to big trouble fairly soon.

 Cracks just past the port on no. 2 and 3 cyclinder

 Crack runs all the way to the port

 Exactly the same but not so developed. Must be a (very long term ) casting weakness.

 The cylinders affected are severely crudded up

 And the pistons a bit, but it's all OK to clean up and rebuild to be a spare engine should there be any trouble with the new one.
