Question about oil pressure gauge in 04 Rubicon
 

I have a 2004 Rubicon with 20,000 miles and LOVE it! I have just noticed
when I start the engine my oil pressure gauge stays at 0 for a second or
two then slowly climbs to normal in about 5-10 seconds. I've had my Jeep
for about 6 months and have never noticed it taking so long to get to
normal pressure. Is this normal and I just wasn't paying attention to it
all along.

Re: Question about oil pressure gauge in 04 Rubicon
 

That's very serious on a new car, could be just a stuck check valve
that is replace with every oil filter. A change of oil may fix it, if
not take in to the Stealership and leave it over night for them to at
least document it.

Re: Question about oil pressure gauge in 04 Rubicon
 

BRING IT BACK!!!

I had the reverse problem, at around 30k, seemed like i was losing pressure.
Mine turned out to be a bad guage.

Good luck.

I'll bet he has a cheap Fram filter in it, or the equivalent.

Hi Earle,
I use Fram, mostly because I still have a case left, but they are
on all my cars, two with over three hundred thousand miles.

Re: Question about oil pressure gauge in 04 Rubicon
 

I have a 2005 rubicon 8k miles my jeep does the same thing. I too was
just starting to wonder. I was thinking of going to a dealer and test
driving a new jeep and see if it did the same thing. Or take it in to
the dealer.

I dont recall if it always did this or not. Maybe I am worrying over
nothing and the guage is slow. Let me know what you find out.

Re: Question about oil pressure gauge in 04 Rubicon
 

Sorry for the top post, but:

Back when I used to drive Slant 6 cars (1980-1999), I noticed the following:

1. On the Slant 6, just like the 4.0 Jeep, the filter sits upside down
so that gravity tends to make the oil flow back out of the filter and
into the pan when not running.

2. Despite the claims made here and elsewhere, based on my oil lights on
3 vehicles over almost 20 years, Fram filters tended to hold pressure
overnight better than AC, Motocraft, Mopar, and a few others. Purelator
was an exception...they always worked.

3. Some, like AC, would work fine until a good long run at high speed.
After that, they would cause a delay in putting out the oil light when
starting. Some (mixed brands) had the same behavior from the first start.

4. I finally gave up on the Slant 6s and used Frams. Sure, the
construction of the anti-drainback valve may appear flimsy, but it
always worked unlike most others. Perhaps that cardboard/rubber flap
actually works better in service than the more logical systems used in
other filters. Several times, after an oil change, I had to replace
"Xbrand" filters with Fram to hold oil in the filter overnight. The
Frams always assured a quick oil light turnoff until they got replaced
at the next oil change.

5. On my XJ, after reading the assorted oil filter tests on the web, I
switched to Purelator and have not had a problem. But the only stores
that carry them locally, (Pep Boys) tend to run out of the proper
filter, so I have to buy several when they are actually in stock. I'd
use Fram again in a pinch.

6. I'm not commenting on the filter medium itself. Just the
anti-drainback function.

Best Regards,

DAve

Re: Question about oil pressure gauge in 04 Rubicon
 

Hi Dave,
The spin-on part of the fram oil filter, the part where the flapper
disk is located is probably the strongest of any of the makes as anyone
that's tried to chisel off one that was installed with a wrench will
testify. Only thing people may bad mouth the fram about is their
filtration area is a little smaller, so I use the largest size that will
fit: http://minimopar.knizefamily.net/oilfilterstudy.html

Re: Question about oil pressure gauge in 04 Rubicon
 

Hi Dave,
The spin-on part of the fram oil filter, the part where the flapper
disk is located is probably the strongest of any of the makes as anyone
that's tried to chisel off one that was installed with a wrench will
testify. Only thing people may bad mouth the fram about is their
filtration area is a little smaller, so I use the largest size that will
fit: http://minimopar.knizefamily.net/oilfilterstudy.html

Re: Question about oil pressure gauge in 04 Rubicon
 

The 4.0 liter engine originally used a PH3985 or equivalent, with a metric
filter adapter having 20mm-1.5mm thread. In 1991, Jeep switched to a PH16
with 3/4-16, which is what many Chrysler products used. This appears to
have the same base as the larger PH8, used on older Ford and Chrysler
engines.

Can you substitute the one quart filter for the half quart filter? I
suppose so, but I have never done it.

Re: Question about oil pressure gauge in 04 Rubicon
 

I hear you Bill. A bit less surface area is of course counterbalanced by
more frequent oil and filter changes. Most of my vehicles see relatively
few miles vs. months, but nearly all of it in Los Angeles traffic. So, I
go with 4 months/3000 miles.

Interestingly, on the carb engines, oil would get dirty much faster than
more modern FI engines with similar age/mileage. The newer engines
certainly appear to reach operating temp faster, and this may be the
difference, not spewing as much unburned gas into the oil during warm up.

Anyway, I've nearly stopped doing my own oil. Living in an apartment
these days with no good place to do it, it is just simpler to go to the
local shop for those messy fluid draining chores. I still do about 1 in
3 so that I'm sure to crawl under the old XJ and have a look around. You
never know what you will find lurking...

DAve

Re: Question about oil pressure gauge in 04 Rubicon
 

I hear you Bill. A bit less surface area is of course counterbalanced by
more frequent oil and filter changes. Most of my vehicles see relatively
few miles vs. months, but nearly all of it in Los Angeles traffic. So, I
go with 4 months/3000 miles.

Interestingly, on the carb engines, oil would get dirty much faster than
more modern FI engines with similar age/mileage. The newer engines
certainly appear to reach operating temp faster, and this may be the
difference, not spewing as much unburned gas into the oil during warm up.

Anyway, I've nearly stopped doing my own oil. Living in an apartment
these days with no good place to do it, it is just simpler to go to the
local shop for those messy fluid draining chores. I still do about 1 in
3 so that I'm sure to crawl under the old XJ and have a look around. You
never know what you will find lurking...

Best Regards,

DAve
