Hello Alpines:
I removed my oil pressure relief valve from the Series V this evening
and here's the results. Thanks for all the tips and suggestions,
including the help from Jim Leach and Roger Gibbs.
I had to remove the oil filter and slightly loosen one of the oil cooler
lines to get to the nut at the end of the valve. Then it came out pretty
easily with an 11/32 spanner. I noticed that it was not screwed in very
tight when I removed it and I hoped that maybe it was loose enough to
let pressure by and not activate the valve. (There was a bit of oil
around the filter base). No such luck as when I reinstalled it, oil
pressure still reads dangerously high. In fact, the system was
pressurized so much that when, about 5 minutes later, I thought I'd
unscrew the old oil filter again and put a new one on, in case the
filter was defective in some way and causing a problem, even with the
engine off for the five minutes, when I unscrewed the filter the second
time....POOF....a pressurized gush of oil sprayed all over the place
from the filter base! It sure woke me up!
Here's a description of the valve itself and what I found. It does
appear to be the earlier brass assembly. I took a small pole and pressed
down on the spring loaded inside piston a number of times. It does take
a good effort to depress the spring (maybe too much), but since this is
my first experience with this part, I don't know what to compare it to.
When the internal piston is at rest (not being pressed in), it's about
3/4" inside the end of the tube. Is this normal? There's nothing
externally odd about it, as far as I can tell.
One thing I did notice is that there seemed to be some rubbing, or
resistance that you can hear, when the piston is pressed in. It doesn't
seem enough the stop the piston from moving under pressure, but maybe
when oil is involved it is. Again, I don't know how much effort it
should take to depress the piston (and spring), and if that bit of
"resistance" I heard is normal or if the movement should be totally
smooth. Any advice would be appreciated.
It looks like I'll be calling Rick at Sunbeam Specialties in the morning
to order a new, upgraded filter base and relief valve, unless someone
has a different suggestion.
