Is it possible to replace the valve cover gasket on a 1926 without removing the manifolds?
Looking at the 1926 engine in my barn, I'd say it may be theoretically possible, but I would at least get the intake manifold out of the way.
Gary, it should be possible. I do not think you can remove the side plate, but it should be possible to get it far enough out of the way to slide a new gasket into place behind it. It my require removing one/both studs.

yes I have done it
Manifolds no, generator yes. At least that is what I had to do on my 25 to fully remove it so I could clean things up.
Didn't they change from studs to bolts by '26?
I've had mine off. I have adjustable lifters and I set them without removing the manifolds. If you have a Holly or other carburetor you will need to remove the rod first. I think if you have a vaporizer, you might need to remove the manifolds. Mine have bolts not studs.
at some point late 26 .... august????
Thanks for the info guys. I'm going to give it a try.
If you have the bolts which would be correct for a '26-'27 it's not a problem.
Done it many times. Takes a bit of fanegalling around and past the generator but hold your tongue the right way and it's a breeze.
I have a freshly rebuilt motor that is leaking a steady drip from the valve cover when the engine is running. It doesn't seem to me that there should be that much pressure in the valve chamber.
Other than a loose valve cover what should I be looking for?
Make sure the drain holes at the bottom of the valve galley are clear so any oil that comes in the chamber can run back into the crankcase.
Also check and see that your valve cover is not bent.
They do not need to be put on too tight this can warp them and spring them at the ends and more likely to leak.
I have done it on out '21 with the two covers. Can't say about a one piece cover. It might be harder, maybe easier.
Yes. I have done it many times.
It's been a while, but I am sure I had it off on my 26. You do need to remove the throttle linkage.
