1,000 miles. Nothing to do about it, it is within factory standards.
Adjusted the valves in Austin yesterday morning, and only gained an hour on seven valves, lost an hour on one exhaust valve.

definitions:
Hour ; the position of the adjusting screw slot
"lost" , if the screw was at 9-3 o'clock, it is now at 8-2 o'clock, this would be a slight valve seat recession indicator
"gained" if the screw was at 9-3 o'clock, it ended up at 10-4 o'clock, this means wear.

Welcome back

Oh. That's not bad. That's half my consumption.
I got one exhaust valve (#1) gaining an hour every 100 miles. I wonder how long I have before it goes kablooey.

You can't use the same terminology with solid lifters, I don't think.

Maybe you can. If your adjusting screw was 9-3, for example, you are saying that you have to tighten down the clearance and it ends up at 10-4?
If that is the case, you have wear occurring somewhere, lifter bottom, rocker shafts . . .

You gonna get out there and pull the head, Hippie? I'm doing one this weekend. Don't want to wait too long. You'll end up doing this:

Every time. I see these pictures and freeze up rigor mortisville. It does not matter that it was 70* and sunny today, that cold oily dead machinery in the snow . . . . . . . . .

Maybe I said wrong. I am losing the valve clearance. The valve, like, keeps tightening up and losing the gap--and it's getting worser and worser.
I can set 'er at .008" and by weeks end, I can't even get a .004" feeler gauge in there.

Gaaaawwww!!!!! I'm gonna tie a snow shovel to my antenna and drive south 'til somebody asks me what it is!!!!

Unfortunately, I have to pull the engine and strip it to the long block to get the heads off on the T-1 design. Won't be able to have time for all that until maybe December...

Do not even start the engine. No fooling around.
If you are lucky, it is a stretching valve that you can replace for $8.99 and just lap it into the seat. But this option has you in the highest danger zone if you start the engine. More expensive but safer for the person who dares start the engine again, is a valve seat that has worked through the surface hardening, you will see a ridiculous wide shiny seat contact area. This is what happened to my Squareback, I paid $55.00 for a new seat to be shrunk into the fine OEM German head. More expensive yet, and mid-dangerous, is a seat recession where eventually the seat could hula hoop the valve and break it. Here, you have to ask what makes the head get so hot. You would be getting a new head in this instance.

Oohhhhh--it's that bad?
Poop poop poop. I've been driving it 200 miles a week on the highway.
Well thanks much for the info and sorry to hijack the thread.

After all the apprehensions you had I can't believe you're actually driving BobD on the itinerary. It's a beautiful Bus and deserves to be driven. But I'd be so worried about it getting dinged or something.

I say drive it. Load it up with kids and take them to a swimming hole in West Virginia or something. Teach some 16 year old how to drive a clutch with it. Rejoice when parts wear out from use. Take it someplace nice and drink champagne out of a dixie cup for breakfast with someone you like.

Sometimes you have to let them ponies run. They like it.

BobD told me the best miles he ever had with that bus was when it was loaded up with 7 years olds going to the zoo and singing "Old McDondald had a farm".

In olden days when I had motorcycles, I would take a new one home and lay it down right in the driveway first thing.. Put a good crease in the tank. That was the pressure was off.

We all rent here on earth and you do not get your money back. That includes buses.

I've heard that if you buy a new mountain bike you're supposed to lift it above your head and drop it. Same principle I guess. If you plan to use it it will develop "character" and it's all part of the game.

is it money in the bank... or is it a bus? Let it be a bus!

That's why I did a cheap paint job and put my money elsewhere into the project. I figured I'd be so worried and then pissed when something did happen, that I should just paint it cheap and easy then I won't be so worried.

I Love BobD though. Simply a beautiful example of a Bus in it's glory.
