Cylinder Bores

Keep at it Will and listen best to the Pros,
It's all very well asking for opinions but in the end, who do you take your accounts to?  not a mechanic who does it for himself part time, so don't expect expert advice from an accountant who mechanics part time, hope you know what I mean. (no offence meant to anyone who gave advice though)  And anyone telling you to bodge it and slap it together, well, just laugh and nod.  :D

Good luck and have belief, it WILL be worth every penny.

Ron, I never know whether you're being serious or having a joke.

I'm not joking in this case. Are his rods bent?

I can't  tell from his pics, other then he may have been using a wide angle lens?

Bent connecting Rods? He may be using a wide angle lens on his camera!

Not necessarily bent, perhaps poorly machined.

Easy to detect, no carbon build-up on the top piston ring groove land in the plane of the gudgeon (wrist) pin on one side only.  Not too bad up to a certain degree, more, and the engine gets really noisy because of the pistons slapping around at an angle.

Excessive normal piston slap will show carbon residue on the top land in the plane of the pin (on the piston "sides"), but not perpindicular to that (front/rear), the piston clearance allows it to be rubbed off on the cylinder wall.

Personally I've never seen a bent rod unless you drop a valve which usually causes catastrophic engine failure, other then a Machinists can strip a connecting rod bolt which will cause insert bearing failure before catastrophe and the knock warning.
