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:

All information that you provide to us for your membership is correct.
You will not use your membership to spam, harrass, or exploit other members in any way.
Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.
No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
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.
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:

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!)

I changed oil on my 37 Tudor and I went by the original manual for oil capacity and it stated 5 qts. I read the dipstick afterwards and it read high. Should I go by dipstick or manual? Also what type of oil are you guys using? Thank you.

Which engine does your '37 Ford have? The manual states that the oil capacity of the 85 HP engine is 5 quarts while the capacity of the 60 HP engine is 4 quarts.

The oil that I use is a conventional Pennzoil SAE 30 High Detergent Oil along with an additive to provide the proper amount of ZDDP to reduce camshaft and valvetrain wear. One additive that provides the proper anti-wear components is Red Line Engine Oil Break-In Additive.

If you don't want to have to add additives to your oil, you can use Valvoline VR-1 Racing Motor Oil which is available in several mono and multi-grade viscosities. This VR-1 oil also contains the proper amounts of ZDDP.

That is not unusual. When I drain my oil, get 3-1/2 to 4 guarts out., so that is all it will take to fill. Others have posted similar experiences. I go by the dipstick. Not good to over-fill.
I think the capacity figure in the book applies to a brand new engine.

I always use 5 quarts to fill the pan. That is what the Owner's manual calls for.

TomO as always has offered you precise information. Your engine was designed to be filled with five US quarts.
The fellow that responded stating his held 4 1/2 quarts has an issue or two with his engine.
The dipsticks have often been changed and as such may not read correctly.
Very often, the dust "washer" that should be present just below the dipstick metal shield is long gone. This 'washer" was made from dense wool and was about 3/16" thick.
Last and also very common is the oil pan has a lot of sludge in the bottom.
Given some thought, it's easy to visualize how any and all of the aforementioned possible issues could affect the true level depicted on the stick.
