What a project but I would rather be working on the bike. I hope nobody buggers up their gasket surface with this idea or the pushrod tube press. That was pretty funny.

You should use the tool a bit and see if it works. It surely won't as photoed. The flat bars will hit the head. The funniest thing is I can't figure out what keeps the valve from going down too? The whole point is to keep the valve in one place while the cap gets pushed down?

I think the edge of the valve will hit the wood table top and should separate at the keeper end but I don't see how you are going to grab the keepers when removing or replace them when reassembling. And because the valve moves at least till it contacts the table there may be even less room to move than appears. It doesn't appear to have enough room.

I don't have a picture to show but for removing valves I have two tools. I don't think either one is right for an Airhead and I use one for removing and the other for assembly. One is a large C-Clamp type which I have brazed a socket on the end to make the right size. The other is the KD type.

That sounds like a good way to bend a valve. It doesn't appear to work but surely someone with no experience will come in and say otherwise?

Yes I think you may bend a valve but I also think it just won't work.

Nice try Plaka. Maybe something along this line could be developed or used in a situation where you don't have the right tool. Have you tried to actually use this thing?

Not on those heads or they would have gouge marks in them.

I'm letting the gaskets season and I'll torque it all down tomorrow.
What kind of sensor?

I figure this is as good as I'm going to get for the hottest oil. I don't think the sender at the pan really showed how hot the oil was getting. I'm after the peak number. I have an imersion thermocouple I'll rig in a cork to get some accurate pan temperatures (temporarily) and check the difference.
Interesting, thanx!

I grab the keepers with either a pick, a pair of hemostats or a small bar magnet. I usually lay out all three and grab this or that.


if you do the socket routine a 7/8" oxygen sensor socket is sweet. That was my first attempt but I screwed it up and it was less work to do something else than try to recover it. I still could have used the socket with my arbor press and a wood angle plate but that isn't the sort of stuff owned by people without a valve spring compressor.

Was that your tool I saw? Big C-clamp with two pieces of key stock welded on?
The concept here is much like a VW tool I've seen, used for changing valve springs on an assembled motor.

I've been able to use a conventional Craftsman valve spring tool, but I admire the creativity here.

Took more time to take the nuts off the bottom and switch the tool to the other side than to put the keepers in. The valve has all kinds of float in the top cap and the thrust is withing fractions of a degree of strait down. The keepers just dropped in---which requires the valve be centered in the cap---so what's to bend? Careful who you listen to old son...I have the thing in my hands, I don't have to imagine anything.

It could use some refinement but it wasn't worth it for something I use every couple of years at most. Already it's faster than anything I've ever used. Don't look fancy but the geometry is right and the leverage is huge, you don't have to lean on the prybar a lot.

Oh no, you would never post things that don't work nicely. Like seasoning your gaskets, for instance.
