OIL PRESSURE LOW 93 Eagle Talon 78000 miles
Ok I picked up a beautiful 1993 Eagle Talon, great shape runs fine,
but heres my problem, which I have seen quit abit as I am researching
today, the oil pressure gauge is flunctuating, I already did the
obvious and changed the sending unit and the sensor, it seemed to do
better it was right in the middle, runs great, but after about 15 to
20 minutes running it, it goes down again, almost to nothing, if I rum
up the engine it will kick back up to where its suppose to be at but
when at an idle and jumps right back down, I have changed the oil in,
this car only has 78000 miles on it, I picked up from an auction, I am
not keeping it, I bought it to sell but I do not want to sale it for
someone else to half to deal with, thats not right, I have been told
it cold be a clogged screen, oil pump, and of course the bearings, I
don’t think it the bearings, the engine runs very strong, then I was
told that the oil pump usually never goes out. So why am I writting,
because after all the research I have come to the conclusion that this
is common with this car, so now I would like to hear from people that
said they got it fixed and this is what fixed it. PLEASE

Re: OIL PRESSURE LOW 93 Eagle Talon 78000 miles
I'm not certain that there is anything wrong. After 15 to 20 minutes of
operation, your oil is hot and pressure drops. At 750 rpm idle, you should
see 10 psi on a fully warmed up motor. If you rev the motor, the pump
increases pressure. When rpm drops, again so does the pressure. I run a
mechanical oil pressure gauge on my A-pillar and look at it all the time.
Pressure varys with temperature and rpm and ranges from 10 to well over 100
psi.

Man, I wish we could edit on usenet... Pressure VARIES with temp.

My '94 Talon (130K miles) has the same issue. My idle speed is lower
(haven't taken time to adjust) and pressure is on the LOW end when hot. I
use Lucas oil stabilizer and it seems to help a bit (especially with slight
valve knocking).

Thank you for your comment, I had the pressure checked yesterday and
was told the pressure is great the lowest it went was 20 and the
highest was 90 so I was told not to worry about it, this is a car I
bought just to sell but I wanted to make sure that I wasn’t giving
anyone allot of headaches, I bought the lucus yesterday also a 20/50
oil weight for it, I was told that was what to do in the summer, so we
will see after that.

Too much oil pressure is not a good thing. That Lucas snake oil and 20/50
are better suited to the gear box on someone's Civic.

Those are not your valves knocking. It's a hydraulic valve lash adjuster.
There is a revised part that does not tick and it's an easy job.

"The first version of lifters used on early 1Gs (possibly up to early 2Gs)
had extremely small top holes. The second version had a top hole about 3-4
times larger, and a larger groove on the side. First version is on the left,
second on the right. Note that the second version was also slightly shorter
in total height than the first. The third and latest version (as of 2004) is
the same total height as the first version, has a top hole the size of the
second version, and a side oil feed hole larger than the first or second
version for even more oil flow to the followers."
"If you want to pick up lifters a lot cheaper than factory costs, the
lifters I recently bought are not Mitsu packaged, they're made by TopLine.
Apparently Mitsu buys the TopLine lifters and repackages them. I compared
them to photos of Mitsu OEM "new" style lifters, and they appear identical.
The shop selling them is down in Texas, and they sell a lot of items at
wholesale prices. Here's the info:
Prime Automotive Wholesale
2100 Regency Drive
Irving, TX 75062
214-441-1500
Last time I bought them in late 2003, the price had increased a bit, to
about $8-9 each, but still far less than factory cost. "
