Sorry to hear that buddy :-(


I've got one, 7mm IIRC, image quality is very much "early webcam" rather than blockbuster 4k UHD, but it's ok as it's on yor phone's small screen, and infinitely better than not seeing anything. If you get oil onto the lens they are a bugger to clean, but even if you can't get it clean again, it's such a cheap bit of kit it's almost disposable, as in it costs less than abox of beer, so not a big hit to write it off.
They seem to be 640x480, as you say better than nowt
 
And if you haven't they are under a tenner off of ebay these days, well the silly little ones that plug into your phone are that kind of money, but even those are useful.

Mine turned out to be more Cefax than early webcam!

The image on that link is more photo shopped than a fashion model on the front page of Vogue.
 
Cranking with plugs out shot a jet of water into the air. So fault has finally revealed itself. Thought I'd got away with it but must have been some slight damage which came to the fore eventually.
It's in the line up for a replacement gasket now after all.

Sorry to hear that Andy, but now at least you can fix it, and be confident to use it properly again. ;)

Of course it's entirely possible that the HG failure, is secondary to the coolant loss, especially as No4 is furthest from the pump.
 
This actually sounds more like an inlet manifold gasket failure. Oddly, this does tend to fail on cylinder 4 inlet for some reason.
 
All going OK so far.
Hope the elastomer will manage with the 0.5 thou high liner in cyl 4. :rolleyes:
It'll be fine, as the elastomer gasket has thicker fire rings, which allow for I higher clamping force to be applied.

Make sure you use an accurate torque wrench. I'm waiting for my FL2 HG to give issues, as after doing the engine, I discovered completely by chance that my torque wrench would "break" about 20% less than the markings would suggest. :(
 
It is a new 3/8 torque wrench, doesn't mean it is spot on but hoping so.
How to easily check??
Spring balance and maths?

Three ways of checking, one is as you say a spring balance and maths, but that leaves you at the mercy of the spring balance, so probably best to go for a known weight + radius like a One Wheel Up Test. Another is to get it calibrated by a third party. Third one is to blag a shot of a bench mounted torque tester You won't want to be buying one of those as they are around a grand. But, they give you dead on (+/- 1%) torque readings, they are widely used in marine and aviation settings. One company I used to work for wouldn't let you do anything with a torque wrench's own settings, it had to be set on a tester, and the tester itself was frequently calibrated.

That being said, I took my three torque wrenches into get a sneaky off the books calibration check (no new cert was issued) and the two new teng and the one old snapon were within one or two percent accurate across the board, so if your torque wrench is of any decent quality, ie it isn't from poundland, you should be close enough :)
