FORUM RULES: Users agree to these Rules when using Forum.

The site administrator reserves the right to change the terms and conditions of the user agreement without prior notice to the user. It is the responsibility of the user to regularly review the terms of this agreement.

The user agrees to the following terms:

  1. All information that you provide to us for your membership is correct.
  2. You will not use your membership to spam, harrass, or exploit other members in any way.
  3. Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
  4. Commercial-type sales postings will not be allowed.
  5. No mass posting or flooding of the boards is allowed.
  6. No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
  7. VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
  8. EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

    http://donclink.com/deuce_75_1/images/dscn2950.jpg

    Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)
  9. HOW DO I SHOW MY EMAIL ADDRESS ALONG WITH MY USERNAME? You can LogIn on the Forum, and select PREFERENCES. On this page Members can add optional information such as their City,State, Country; Occupation; Hobbies: list a Homepage; list AOL Instant Messanger Handle; Signature; "Make Email Address viewable to others;" and even change the number of Default Topics shown on a page. WHEN others click on your profile, they will see this information.

sound like the oil pump screen is clogged or the relief valve on the side of the pump is stuck open. also did you change the fuel pump, maybe to electric? if the fuel pump push rod was removed that can cause low oil pressure. I have cleaned the screen by filling engine with kerosene and let it soak for overnight, have also used a blower heater to heat up the oil pan to loosen the sludge, any chance it has the truck clean out bottom plate? if so remove an clean sludge

which oil filter do you use? and when do you change it means how long do you use one filter? I had faced this problem in a towing truck of 24 Hour Towing in New York, but after discussing with someone on a forum he suggested me to change the filter this is how I got the solution.

Well, Just a little up date here. After 2 months or more, Put my truck in the hospital for a heart transplant.
for a truck that ran almost like a new one it did have some issues.
like the block was cracked in several places. no leakage anywhere. it had 3 different kind of lifters in it, different kinds of valves, 1 cracked head, the reason for low oil pressure? Who knows. Everything was rebuilt back with all new parts. purrs like a kitten now, with 50 pounds oil pressure.
Thanks to all for your help and suggestions.

This is a related oil pressure question.

I had a NOS oil pressure sending unit in my rebuilt '53 engine ('51 truck). My dash gauge always showed 50 psi after I rebuilt the engine. The NOS sending unit failed. I ordered a new sending unit from Carpenter. The dash gauge read 30 psi. Got another new sending unit from Carpenter. Dash gauge shows 30 psi. Checked oil pressure with a mechanical gauge and got 50 psi. Of course Carpenter knows nothing. Any ideas why the new sending unit only shows 30 psi at the dash gauge?

Richard, I suspect that the reproduction sending unit is the variable resister type and not the King Seeley type. If you have the NOS one (check for KS stamped into the cover to make sure that it is the correct one), it can be repaired by one of the people that advertise in Hemmings. Bob's Speedometer may be able to do it.

See this E-Bay item for the stamp

HI
did you try grounding the wire going to the oil pressure sender and see if the gauge reads higher ? with the sender disconnected
IT MIGHT be as simple as a bad sender or corroded wiring , connections ?
hook up a mechanical gauge and run the engine and see what GAUGE reads,
DIAGNOSIS problem FIRST
before major work that may not be needed,
I bought a 8N tractor that had a bad gauge, I am sure the owner thought it needed rebuilding,
motor ran with no noise and gauge did not move, replaced gauge and never had any engine problems,
hope this helps.

I have posted this question too many times and no one has the answer.
All those oil gauges are marked 0 30 80 I am bad at math, but
ain't half of 80 40? My car hot idle, says 30 and my mechanical says 40:
If I move the car even a foot, dash gauge says like 35 and mechanical shoots
to 60 , so what was King Seeley thinking? Ideas any one cause
I don't and I have 5 F6 V8 trucks 2 F8 V8 337s all read the same so its not
senders or the gauges and my every day driver 46 Super Deluxe 59A V8.
And then who has ever had the temp gauge read correctly besides never?

try to
disconnect the wire going to the sender,
and try grounding the electric sender wire to ground,? to see what the gauge does,

I think it should read the highest it can,
if not your gauge is not working correctly
these are not great instruments, that's why the went to warning lights,
so not to alarm owners,
my 2 cents 37RAGTOPMAN
oil pressure relief valve also could be the problem with low oil pressure, broken spring, dirt in it,
might be a thing to check out, also a worn oil pump,

You guys are hijacking nuffsaid's thread. Best for both of you to start your own threads / posts.
