Hi Bob
Bunker C oil is roughly half the prices of regular automotive diesel so in Jamaica diesel is $2.93/gal and HFO is $1.49/gal ($us)
You have to realize that My diesel engine at the power plant burns buncker c fuel and the injector pumps have lasted over 5 years now. The injection pumps are actually made by Bosch with cobalt plungers and if you look at the picture bellow the the unit on the power plant generator have a similar design to the one on the lister engine

We all know that old Lister engines are significantly over engineered and I hope that this also applies to the injector pumps
One thing that dose concern me regarding the piton and liner is the build up of carbon on the upper edger of the piston walls that can get thick enough to start robing on the liner causing it to become polished. The solution for this in the power plant engine is having a steel ring installed at the top of the cylinder. The ring inner diameter is just smaller than the liner's and it scrapes off the excess carbon from the top of the piston crown keeping is from reaching the the liner wall. Eventually this ring dose wear and has to be replaced but the ring is cheaper than a new liner. I may have to do this modification to the lister.
Another modification to the engine will be to increase the oil sump volume to extend the time between oil changes. Also I have a contact at Exxon Moblie oil company and they a lube oil that is very resilient to contamination for HFO particles. We are talking about a super detergent lube oil.
