Hi Doc!

That's a Ford problem, most noteable on a 2.9. But most notorious on a Ford.

The only time I have seen this in the past was a partially plugged oil
pump
pickup screen. After the car was driven a short distance the screen would
plug completely and no oil flow to the pump. After it sat awhile
apparently
the gunk on the pick up screen would drop off and when started would have
oil pressure for a short while until it plugged again.

That's exactly what I was thinking, hence the questions as to OP levels
prior to the problem.

Is it possible the oil foamed due to "overfilled" crankcase?

Is it possible the "overfilling" was cause by an internal coolant leak
draining into the crankcase?

I would drain some of the oil into a pan and check.

Good Luck!

Hi,

In 26 years of driving I've always been a Ford man with an occasional
Chrysler product tossed in here and there. I recently rolled my Ford
Ranger in the middle of MO. ( http://home.comcast.net/~jgibson1 ) While
looking at a Dodge dakota the other day I was about to leave when I saw a
2001 Medium Charcoal Gray Chevy K1500 Silverado LS, 4WD, automatic trans,
4.8L Vortec engine, 8000 LB towing capacity, extended cab, 4 door (the
extended cab doors open), and composite box, with bed liner and nice
color matched cap. For cheap.

My brother in law has a '98 K1500 with the Z1 package and only 73,000
miles. I asked him his likes and dislikes. His complaints were: DexCool
causing leaks and damaging head gaskets, rough, noisy shifting in and out
of 4WD, and the 5500 LB towing capacity.

Will the truck I'm looking at, being 3 years newer and with a different
engine, also have these problems? Anything I should watch for besides
the normal/obvious? I'm especially concerned about the Dex Cool as I'm
used to the green stuff, not the orange.

Thanks
Jay

Jay,

Dex will mess the works up IF, and ONLY IF:

1) It's more than 50K miles old
2) Rad cap isn't working correct allowing air into the system
3) Rad isn't full due to #2 or empty reservoir.
4) Tap water is used to fill the rad (you must use distilled water).

That being said, if you use distilled water and change rad cap + coolant
every 50K you won't have any problems. The Dex doesn't "eat the head
gaskets." These trucks do not have any head gasket problems. The 98's
and older Vortec's (5.0 and 5.7) did have intake manifold gasket problems,
but this was a faulty gasket design and not the fault of Dex. The newer
motors (4.8, 5.3 and 6.0) do not have this problem.

Yours might be a piston slapper, but Ford and Toyota have just the same
issues with their newer motors as well. Do a google search and read up.

Doc

Thanks for all the advice. I bought the truck. Picked it up with fuel
guage on E
and service display window saying "Low Fuel". Filled it up with 25 gallons.
Still
stayed on E with "Low Fuel" showing. Drove it home 92 miles away. After
burning off some gas, message went off and guage went to full.
Intermittant.
Now with half tank, when the needle drops if I hit a bump or bounce in the
seat
it goes normal and "Low Fuel" indicator goes out. I suspect the sending
unit.
Not looking forward to dropping the tank.

More serious issue: 92 miles to my house, all expressway except the last 2
miles.
Got off the expressway and the oil pressure guage dropped to zero and
display
said "Low Oil Pressure". Not wanting to wait to see if it was another guage
malfunction I instantly pulled off the road and shut it off. Started it
back up,
"Low Oil Pressure" message still on, guage still at zero and top end just
starting
to chatter. That verified the no oil pressure. Quickly shut it off. No
bearing
squeal, lifter noise just starting, and zero reading made me think oil pump
went.
Left it there about 2 hours and called towing company. Went there to meet
them
and tried starting again. Started right up, guage went up to normal,
warning
message went out and top end noise went away. 100 more miles and no
problem. Oil pump is mechanical and can't fail then work fine again, right?
I doubt these are related but worth mentioning: Was about one quart
overfilled
with oil, and discovered I drove all that way with front diff in neutral
instead of
2 wheel high. All other guages read normal. I'm baffled and don't feel I
can
trust it.

Summary: Oil pressure was at zero, 2 hours later was fine again. WTF?

Thanks,

Jay

Work, Work and more work!

Glad to see you're still at it!

Since getting the shop, I've been kicking ass finishing my old projects and
getting ready for the new. The building isn't what I really wanted, but at
least it's a place to work.

Salute.

I drained/changed oil as soon as I could. Drained (including filter) into
an eight quart oil pan and almost filled it to the top, so it was closer to
two quarts overfilled. Oil was clean, no coolant. Also, when I changed
the (CRAPA) NAPA filter that came on it I checked the part number and
discovered it was the wrong filter. I'm glad this lot only had it two days
before I bought it so it wasn't driven much this way. Replaced it with the
correct AC Delco filter and the correct grade and amount of oil. 700 miles
later and the truck has been great. Fuel guage problem about 95% solved
after a few tanks of gas. I think it sat a long time with very little gas
in it.

Thanks,
Jay
