radiator repair

["LeDuc, Eugene A." <LeducEA@utrc.utc.com>]

Hey guys,

This evening the top plastic pipe on 85' 5000s radiator
snapped into half so the upper radiator hose came completely
off

That is amazing!!
I've  been with this list for a few weeks and almost ALL of the problems 
with my 5000S have been reported /discussed . Are there mysterious forces at 
work here ... planed obsolescence  ... hexing ... consistency ???
I fixed the radiator (same exact place) with a product called PC-7 ( an 
EPOXY ) so far it's held up great but it sounds like the plastic itself is 
being "attacked" and so any patch is bound to be temporary. the epoxy cost 
$5 so I get to delay the expense of putting in the copper job which was 
debated and discussed thoroughly down to thermostats and operating temp. 
 Which brings me to two more questions:
1. how do I get to read previous posts /where do I get the archives??
2. Has anyone ever seen this one... I am leaking oil (?) through a sensor 
located at the bottom front of the engine, on the left side.  There are two 
sensors located, over and under, smaller white one higher, larger black one 
lower.  The lower one is actually leaking though the body ,where the 
electrical contact emanates
soooo  My question is what is this sensor (I haven't gotten a Bentley manual 
yet) .
I figured out BTW  there are a few others I haven't.

I found a Bentley for the 4000 (1985) but I can't locate one for the 5000 
Could any one out there get one ???

Only my cat .......oh never mind   :-)
