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!)

Do A compression test then do A wet test maybe its valves not rings the wet test will show you which one. put A few pumps of engine oil in the spark plug hole and take another compression test the oil will seal the rings if the compression is higher its the rings if its the same its the valves IMHO my uncle showed me this many many years ago and it works

Please, do not confuse cranking compression, (pressure) with compression ratio. Two different things. You can easily have low compression with a high compression ratio. Ya can't fix a worn out engine by milling the heads.

I would like to send you an email or PM but both of them are disabled. It might be valuable to you if you changed that. A general location might also prove valuable at some point. In the meantime, how about sending me an email at the address shown in my profile?

Hello:
1. An unscientific question to ask. Did you check your 59A block compression at 5000 (approximately mile high) feet? If so, do you have the opportunity to check your compression at near sea level to see if your compression increases or remains as 60 pounds at your advertised altitude?

2. Would you consider judicially shaving your heads or using a thin copper gasket to increase your compression at your mile high geographic location? As usual, shaving a head or using a thinner head gasket on a flattie may run the risk of valve interference into the head or reduction of airflow.

I would not replace the engine when low compression is the only problem.

The engine should be at operating temperature (drive it for at least30 minutes, maybe longer in the cold weather), the throttle should be wide open and the battery at full charge before taking a compression reading.

If your readings are consistent across all 8 cylinders, the engine runs smoothly and seems to have adequate power, I would leave it alone.

If it is lacking power, I would talk to someone in the High Country Regional Group about timing and carburetion for high altitudes.

One more thought: Did you crank the engine over at least 3 revolutions for each cylinder?

I keep the battery (Optima) on a charger and it appears to be strong. I did not have the throttle open however. I will retest it, I assume this is to make sure the is adequate air getting to the cylinders. The procedure was to take a compression tester on each cylinder and crank it with a remote switch. I did check the compression tester against my air compressor and it seem pretty accurate (set the regulator to 60lbs and the compression tester, with adapter, read same.) I really appreciate the thoughts.

Was the battery strong and did you hold the throttle open when cranking it? Is your compression guage accurate?

What procedure did you use to check the compression?....
