Re: kerosine cleanout?



basically: temporarily replacing some or all of the engine oil with a 
lighter lubricant to dissolve / flush out deposits before replacing with new 
oil. I've never done it with kerosene but I have done it using diesel, by 
draining all the engine oil, replacing with diesel and idling the engine for 
5-10 minutes. Diesel has the possible advantage of being full of detergents 
which may get rid of more deposits. I've used it to successfully cure noisy 
hydraulic tappets, especially on audi I5 engines which seem to be 
particularly prone to this.
