| + | * Take the cam cover off without dropping anything in the drain pan or on the floor while preserving where all the shims are positioned. | ||
| + | * Try not take the cams out unless you Need to. | ||

| + | * Now look in the gap, and with a skinny screw driver, push all the cams back into the engine so that they won't come out with the cover. | ||

| + | * Now, you will be able to see the shims if there are any in there. | ||
| + | * Use an ice pick to work any shims, that are hanging on the cover bushing flanges, back onto the cams. | ||
| + | * Make sure the cams hang inside the motor using the skinny screwdriver again as you work the cover off. \\ Note that the cover is still engaged to the cams and that they are slid fully into the motor side. | ||

| + | ====== Inspection ====== | ||
| + | * **Inspect the cam bushings**. Check the clearances per the service manual and replace any out of service bushings. Also check for scoring or scratches. [[techtalk: | ||
| + | * **Inspect the point cover/ | ||
| + | * Look for ID leaks; a marred cam journal, seal lip not getting up on the full journal diameter or a missing dog bone thrust plate on far side of cam. ((Dr Dick of the XLFORUM https:// | ||
| + | * Look for OD leaks; the seal bore nicked, tearing the seal OD when installing it. | ||
| + | * Look for scratches, gouges or wear marks on the cam shaft where the seal seats. If there are any, they need to be removed or the shaft changed. Also check if there are any gouges or cracks around the outside diameter of where the seal fits in (bore). These can be put there during seal removal and let oil seep out around the outside of the seal. They can usually be scraped or filed back flat. You can make a scraper by grinding the teeth off the end of a three-sided file. | ||
| + | * **Inspect the breather vent/ | ||

| + | * With the cover installed: (do-able but arguably not the best way) | ||
| + | * The seal can be a bit tedious to remove. ((IronMick | ||
| + | * You can force it out with a pointed tool, an oil seal remover tool or a flat blade screwdriver. ((IronMick of the XLFORUM https:// | ||

| + | === Installation === | ||
| + | The seal is pressed into the cam cover to seal #2 cam shaft as it protrudes thru the cover behind the the points or ignition plate. \\ | ||
| + | * Lightly grease the lip (the part that surrounds the cam). However, the seal OD should be installed rather dry or with an appropriate sealer (not RTV). \\ A thin layer of non hardening aviation gasket sealer etc. around the seal OD lubricates the installation. ((Hopper of the XLFORUM https:// | ||
| + | * Then you can tap a new one in with either an oil seal installation tool or a socket of appropriate diameter. | ||
| + | * If you decide to pull the cover to change the seal (better idea), remove the push rods FIRST. ((8ball of the XLFORUM https:// | ||
