[doc] Re: plunger in fuel distributer

["blackaddertoo" <blackaddertoo@xxxxxxxxxxx>]

hi

i haven't yet as the engine is in pieces.

i will once i put back together if it does not run.

however i think it is a good idea to open up the valley for 
everyone, and clean up well. your coolant pipe will leak in there 
sometime-just a matter of when.

there is some corrosion at the bottom-not bad though.
for the sensors, if they work or not, while i am there better 
prevent further problems, particularly as not expensive as some 
other things.

regards

Steve
