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!)

What year Ford V-8 engine are you working on? Has the engine been run recently? You can get the valves out of the engine with the engine in the car. Getting the valve guides out of the engine can be a real challenge.

To make the job easier, remove the hood from the car after marking the hinges and surrounding mounting surfaces. This is done so that you can more easily replace the hood in its original position.

You will need at least a couple of special tools to remove the valves: one is a valve lifter prybar to pull the guides down and the other is a hook to remove the valve guide retainers.

The earlier 239 V-8s 1948 and earlier have split guides which must be kept together as they were originally installed in the engine and mushroom valve stems. The later 239 V8s, 1949 & later passenger cars and 1948 & later trucks have one piece guides which are a little easier to work with and straight valve stems.

If the valves are not in too bad a condition, you may be able to free up stuck valves without having to remove them from the engine.

One way to free them up is to remove the cylinder heads after draining the coolant, remove the intake manifold and use a good penetrating oil and/or Marvel Mystery Oil on all of the valve stems and guides. Allow the oils to soak into the spaces between the valves and the guides overnight.

Turn the engine over by hand in a clockwise direction (to keep the crank pulley bolt from coming loose) by using a wrench on the crank pully. Watch the valves while you rotate the crankshaft. Some of them may already be loosening up. Those valves that are stuck open can be freed up by carefully doing the following: first make sure the tappet for the frozen valve is contacting the base circle of the camshaft lobe (valve closed position) then hit the top of the valve squarely with a rubber mallet to drive the valve down to the closed position.

You may have to repeat this procedure for several days to loosen up some of the stubborn stuck valves. Once you have all of the valves freed up check the valve clearances as measured between the valve stem and its tappet.

If the valves clearances are smaller than specified, the valve can be removed and the valve stem end ground squarely to achieve the required clearance. If the valve clearances are too loose, the valve sealing surface can be ground to reduce the valve clearance.

By the time you strip the engine in place to work on the valves, you may as well pull the motor. This will allow an inspection for necessary repairs, and upgrades such as new hardened valve seats, as well as a thorough removal of sludge, etc, from the valve valley and oil pan.
