I waded through previous posts, did several searches and found this
topic covered a few times, but I was hoping to find a bit more detail.
The oil pressure in my 99 C5 reads 130 constantly (from startup). The
analog dial is constantly pegged. I've had it for about 10 months and
it's always read that way. It wasn't until my wife sitting in the
passenger seat got bored and decided to flip through the manual and
asked why the pressure was so high.
I've had no engine performance problems, and have had 2 oil changes
since purchase with no change.
So, reading the forums, it seems one likely culprit is the "oil
The consensus seemed to be that this is a 'doable' project. So I went
on a quest for a repair manual and part. Well,
A) I can't seem to find a repair manual for a 99 C5. The impression I
get is that it doesn't exist. Seems like the Chilton/HP manuals stop
at about 96. After that it seems to be engine specific, body repair,
etc manuals. Found one Service manual set on Eckler's for $190, but
seems like that may be overkill. Am I missing something?
B) Can't find a part called an "oil pressure sensor". Found plenty of
"oil pressure guages" and "oil pressure senders", but no sensors. Does
it go by another name?
I appreciate any assistance.
