Early Ford V-8 Club Forum

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.

After eight years I have my 34 Ford on the road. Drove it to work and Rotary this week. What a pleasure. But . . . Sticker valve is causing pops and farts. Rather embarrassing. Engine had not been run much for at least 30 years, but compression is good on all but one cylinder. Probably the one with the valve problem. Any ideas on how to unstick the valve. Am running SeaFoam and MMO In the gas.

To confirm that a valve is the problem, run a dry/wet compression test on the low cylinder. Test compression, then insert oil in the cylinder and compare results. If the wet compression shows a large increase, the problem may not be a valve, but a broken or stuck piston ring, a leaky head gasket, weak or broken valve spring or retainer, or other cause. As you say only one cylinder is affected in an engine that hasn't run for that long, one stuck valve seems odd. Most stuck valves are due to carbon buildup from oil consumption, and only pulling the head and intake manifold to remove the valve assembly is a reliable cure. Most oils, etc, will not dissolve carbon.

Thanks for the tips. My plan for now is just to drive it. It seems to be getting a little better. I put a nos set of c7 plugs in it yesterday. The plugs that came out were cooler and sooty. The popping through the carb seems to go away with a little choke. Maybe thinks will settle in.

Sooty plugs and backfiring can also be due to a vacuum leak. Check all connections to the intake manifold, such as the wiper hose and distributor line. Squirting a bit of carb cleaner on suspect places can help. If the engine speeds up at idle, you have found the cause. Another cause is a worn carb throttle shaft and a throttle plate that doesn't fit the throat.

Thank s Superreal, I will check those out. I think the carb is good, it's one of the new Strombergs, but it could be a vacuum leak. I'm try the carb clea near trick. Esteban

t hey have these little cameras on the end of flexible line, maybe you can find a garage that has one and look down the spark plug hole. or just squirt some pb blaster down around the valve stem

You can also run the MMO in the engine oil, check the container for instructions. Beside helping to free a stuck valve it will assist in freeing stuck piston rings and help to stop burning oil. I am not recommending using it in the oil with every oil change but worth a try at this point. It will help to run the engine and not let it sit. You can also remove the spark plug from the cylinder and with the valve open spray a bunch of the MMO under the valve seats, let it sit for several hours and then run. If it doesn't get any better in a couple of weeks, it is possible the valve is bent, the valve spring broken or excessive carbon deposits on the valve seat. Before taking the engine apart do another compression test to see if there has been any increase in the low cylinder reading.

As you have located the offending cylinder, I'd pull the intake manifold and inspect the two valves of that cylinder. As the post above says,you may find a broken valve spring or other related problem. Old valve springs easily break after years of flexing, and the protective coating wears away. Sometimes the broken spring is hard to see, so pry it up and down to be sure it is intact.
