lister 6/1 som
« on: September 23, 2010, 10:14:37 PM »
The head gasket failed one night so the next day I stripped the engine down just 150 hours short of clocking up 2000 hours.
All this time its been run on waste engine oil mix and there was no carbon in the exhaust port and the head and piston top had very little carbon.
When I pulled the piston the rings and the sides of the piston where carbon free and clean.
I fitted a new gasket and its powering the pc and the house as I write this report.
I think this is good news and I see know reason to stop burning this free fuel.

So what is the recipe for your "waste engine oil mix"?

Thanks for the report.
Very interesting that there was minimal carbon buildup.
How are you preparing your oil prior to use ?
Are you blending it with anything ?

I use a oil measuring jug and put in one and a quarter of thinners like petrol, diesel, heating oil and add waste engine oil up to the five litres or us quarts mark.
Just give it a quick stir and tip in.
The oil is just filtered with sock filters.
I think that because the oil is black you just think its dirty,so when you can remove that preconception from your mind its not a big deal.
Removing the bung and cleaning the carbon that sits behind it is the only extra thing to do,if not it brakes off and the engine makes a nasty knock until it clears.
When I pull the engine apart next time I am going to set the bump clearance to that of a 8/1 and fit the appropriate bung so there is more clearance between the piston and the head for loose carbon.
