Commercial-type sales postings will not be allowed.

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!)

Some shops today are unfamiliar with rope seals. They must be soaked in oil well before installation. At our shop we keep rope seals immersed in oil for the next job. The ends of the seal must not be trimmed, as they will be properly shaped as the pan is tightened.. A dab of RTV on the ends of the seal is a good idea, as well. If you are using full synthetic oil, is is likely getting past the seals. Finally, confirm that it the seal that is leaking. If the pipe plug behind the flywheel wasn't tightened and sealed, it will leak, as will the area around the oil pressure sender. If you don't see evidence of a leak on the outside, it my be a problem with the rings. A compression check will reveal that. I agree with my friend Tom that additives should be avoided. An engine with that few miles shouldn't use a quart of oil if it was properly rebuilt.

Thanks for all of your responses! The oil pressure is 45-50 max. The rear seal had minimal leakage prior to the rebuild. I didn't select the rebuild shop, my restorer did. He's a long time restoration shop in NH, he said that this shop, which mainly does OHV racing engines, was competent. I'm beginning to worry a bit that they fouled up the machining of the crank or something along those lines. The rebuild shop doesn't seem particularly interested in dealing with the engine anymore, the restoration shop says that there is nothing that they can do about it. You get the picture

That much oil leakage on a rebuilt engine sounds excessive to me. If he used a rope seal and soaked it properly before installation, I don't think it will get any better.

Does your oil pressure gauge show excessive pressure i.e. 80 PSI at idle? It could be that your oil pressure relief valve is stuck closed. If you have excessive oil pressure the first place on a Flathead that will leak is the rear main seal. What viscosity oil are you using?

I would not use a "stop leak" in a newly rebuilt engine. Those products are designed to swell rubber type seals and they may affect the valve seals, while not doing anything for your rear main seal.

The 8BA oil pan holds 4 quarts of oil, and you should add 1 quart when the filter cartridge is changed. make sure that you do not overfill the oil pan.

Work with your engine rebuilder, you chose them because they were experienced and you checked out their reputation.

I have a recently rebuilt 8 BA with about 600-700 miles on the engine since the rebuild. It has a rear seal leak, about a qt over the last 400 mi. The shop which rebuilt it told me to put at least 1000 mi on it before they will even consider looking at it. They supposedly are experienced in flathead rebuilds. The rear seal is the rope type. Do any of the rear seal leak stop products ( Blue Devil) work with this type of seal? Suggestions? Thx!
