and yes i know about the PP article.
i want to know how real people do these....

Real people change the pushrod tube seals by removing the rocker arms first. It isn't hard...

Just readjust the valves...
Make sure when you're putting the rockers back on you orient them correctly. They are held on with two C shaped mounts that are NOT symmetrical.

On my Type I engines I removed the head and added some aviation gasket to the surfaces of the push rod seals (The head and case side). This assumes the engine is out of the car.
Never had a leak from the push rods again. Not sure if this procedure is applicable to the Type IV, maybe some one can chime in.

figure out the "mysteries of the valvetrain" before you go digging. yes, you'll need to readjust your valves afterwards. read the PP article a dozen times, you'll be fine.
oh -- and use jackstands when you're under the car.

Yeah, you will have to do a valve adjustment after you take the rockers off. Its a good time to learn. As stated previously.... You also have to be aware of the orientation of the rocker shaft blocks. Its easy to put them in backwards and they are not of uniform thickness. Also, if you want to get a couple of the pushrod tubes out, you may have to lower the engine a few inches. I had to mine were damaged

You DO actually have to lower the engine to get a couple of the tubes out all the way.
One little tip someone gave me is that you can slide the tube out of it's position and remove the seals from each end without actually taking the tube all the way out.
I'd rather take it all the way out and clean it well, but seems like it'd be an option.

The REAL problem is the PUSHRODS. If you can remove the pushrods without removing the rockers, you really do need a valve adjustment - big time.
-----
When you DO remove the rockers, lay everything out exactly as it came apart. Put it back together exactly the same way & your valve adjustment should not change.
Torque the nuts to 10 foot pounds.

My sealant handbook will go over this procedure step by step. I have already written this section of the handbook and I think it came out the best of any other part.
I should have the handbook published by the end of the month.

Don't matter. it's been written here several times. Works really well BTW. Maybe there should be a search of the subject before getting us all through the wringer again.
Britt I have all that tube sealed valve adjustment stuff done to the motor you want to get. Just get down here and get it.

I know it has been explained here a few dozen times, because I have done it most of those times myself.
Most of the other tricks about sealing the engine have not though.

How about if we just have someone steal his keyboard(s) so we won't have to put up with this anymore?

Valve adjustments are a routine maintenance item on 914s. You NEED to do it, pushrod tube seals or not. Just be glad the heads don't have to come off to change pushrod tube seals on a type IV. If you don't want to adjust valves, replace the engine with something that has hydraulic lifters. (late bus, subie, v8, etc.)
