The problems never end

[Tony Griffiths]

Not a bodge - but how does a Chummy door handle get into this state? Not only rusty, but flattened as well.

Threw a mildly bent fan blade away the other day, it would have straightened but not worth the risk.

Not a bodge as such but a repair to an insignificant issue that caused more damage than the issue it was trying to repair!

This was a definitely a bodge.
It's the rotor arm of an ML RF4 magneto, remanufactured from wood with a brass strip screwed on. 
The mag came from Australia where the climate may have been more tolerant.

Hi,
Your opinion about those please:

I would like to forget about them as it was said above but?
Thanks anyway,

It's not the greatest picture but the rest of the bore looks far from good either.
I wouldn't reuse that.
In the case above the engine has even, good compression and doesn't burn oil/oil a plug so it's acceptable.

Well, these days I’d change it, but looking back 30 odd years yes I think I would have honed it and used it again.

And convince yourself that the pitting retains useful oil for lubrication eh?
We've all done that.

I know I already asked but is there any way of filling those gouges in the cylinder wall, they can't be good and while I've got the the piston out I thought I'd like to try sorting it otherwise I'll be paranoid while driving just waiting for it to start burning oil.

[Alan]

I think any form of adding metal will be difficult. I’d be worried about distortion and it becoming detached at some stage. You could get just that cylinder relined - not sure how much that would cost but more than a hundred quid I’m sure. You could burn an awful lot of oil for that.

I would say that there is little doubt that those "tram line" gouges are a result of a loose gudgeon pin resulting from a broken/ loose pinch bolt. When I suffered that, a few years ago now, the broken-in-thread pinch bolt, in exiting the conrod, smashed two pieces of piston from the skirt - not a happy state of affairs. The piston was destroyed, the conrod was damaged beyond repair, all because the previous rebuilder had not used the correct, new, HT pinch bolts!!
( on the up side, I later successfully reused the gouged block in a different engine bored out to +80 thou to accommodate Renault 4 pistons)
