    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

i found out why my tach isnt working. i didnt see it spinning with the engine, so i took the valve cover off and it confirmed my thought. the drive gear for the tach on the cam is stripped.

is there any magical fix for this or do I have to replace the whole cam?
if i have to replace the cam, any tips/shortcuts or things to watch out for?
 
thats a 1 in a million occurance in my experience..care to post some pics...would love to see it.
 
Chuck were there not some issues arising from the use of the "real gasket" silicone replacement gaskets?

I thought the extra clearance caused the gears not to mesh and made them eat away at each other.
 
Use vice grips to clamp down on the cam like the factory manual shows before you attempt to remove the cam bearing caps. I'd put the engine at 1-4 TDC first, and set the lock screw on the cam chain tensioner.

What kind of engine are we talking about here?

Edit: the clamping down on the cams applies for the shim and bucket GS engines. Not sure about the rocker arm engines. Check your manual.

Dont know about that Jeep, but it makes sense seeing that you cant tighten the Real gaskets down fully or else they tend to squish and tear,

When replacing the valve cover I alway just lay the cover on top of the head and hold down lightly while bumping over the motor enough to see the end of the tach drive rotate. Then tighten down before anything moves further. Use oem or cosmetic gaskets and stay away from real gaskets. Gasket thickness is critical.
