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...

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.

Yes - it's the modern way to do gaskets. It's called MLS for multi-layer steel. Works better and lasts longer than old style composite gaskets but it does require more perfectly flat parts in some applications. Check head & block surface for flatness before installing.

Do you mean assembly lube? On the cam lobes & followers? You can use oil if you want but assembly lube is not a bad idea.
 
i mean on the valve shafts themselves. and its a completely new valve

Won't hurt. I always use it on internal parts (except rings).

If you're tight for cash just oil everything down with oil before you put the parts together and dump oil over the cams before buttoning it up. If you've got an extra $5 or $10 buy a tube of assembly lube from Autozone and squirt it all over the cam lobes & followers before putting it together.

Are you tearing it down to replace a stuck valve? I've never heard of a valve just sticking all of a sudden. Bending, yes, sticking from lack of use and rust, sure, but just sticking out of nowhere? That's very unusual.

Be sure you know what the problem is before tearing it down...
 
it was bent. it got stuck, then hit the top of the piston whilst stuck, and bent.

That can cause the guide to move. Be sure to lap the new valve in to see that it is on center of the seat.

Do not push new valves through the valve stem seals without lubing them first with moly or motor oil. You will ruin the seal and smoke out the neighborhood. Some valve seals come with a condom to not damage the seal.
 
is the head gasket supposed to have a gap between the cylinder, like this?
