Hey Guys,
Here are some pics of TM1's Head and combustion areas I took yesterday... Not great quality, but it gives some idea of the (lack of) carbon and deposit buildup after running around 1k hrs or so on virtually 100% WMO ... The water induction on the inlet is doing a sterling job of keeping most of the crud at bay....

What is of interest is the way that the exhaust valve has backed into the head, an old problem, and the main one that made me take the head off to get sorted. Around 1k hrs ago, the valve and seat had started to fail, a temp reseat job was done with only the basic tools I have(Barring a lathe that I used to cut the valve face) and it has survived quite well....
Cheers
Ed
PS - Some interesting stats, bits n' bobs' I have on record to date:
Total Runtime: 2504hrs
Fuel Usage: 3516L, mostly WMO
L/KwH: Currently 0.598
KwH/L:Currently 1.672
L/Hr:Currently 1.404
KwH Last Run Session 2.33
Total KwH Produced to date: 5880
Total water heating LPG estimated saved over 14mo Period: 21 x 14Kg Bottles
Fuel Used: WMO / Contaminated and recycled Diesel, Thinners, Petrol, ATF, Transformer Oil, Paraffin, Various other grades of mineral oil, WVO... if its liquid, oil based and burns, it gets used. (Sometimes, if it just burns its good enough!!)
Residual oils that are badly contaminated with water and coolant left on hand after recycling 3500L of gunk - <200L (Soon to be gone through again and more reclaimed)
Most common used spares for maintenance - Fuel and oil filters.
Other maintenance spares used: 1 x set rings, 2xhead gaskets/Oil pump seal/IP elements x 2
Warranty spares used: 1x Crankshaft/1xBig end Bearing
Highlights(The things that I remember most):
Crank failure at 1500hrs due to bad lube oil standpipes.
Vibration issues and balancing of flywheels
Finding the best injector timing position for WMO
Water injection Installation
Electric starting
Heat Recovery from Exhaust and Coolant
And....
of course....
Lots of FUN!
