Years ago I was talking to Randy Ema and he still had the long hood.

Bill and all,
I had this exact same scenario happen before (although not on a Duesenberg) The substance did indeed look exactly like brown sugar and when I pounded the valves out of the guides they had a brownish coating that looked exactly like dried molasses.
What happened is that I ran an engine that appeared pristine, but had not been run in quite some time. We added fresh gas and the engine ran like new. Once it was shut off and cooled the valves stuck fast in the guides. Application of a good penetrating oil had little effect, nor did gently pounding the valve stems with a plastic mallet.
What we eventually determined was that old leaded fuel had evaporated and the residue settled in the bottom of the tank and solidified. When the new (for 1997) re-blended fuel was added it reacted with the detritus in the bottom of the tank and formed little globules (is that a word?) of goo that went through the entire fuel system. When the engine was hot this stuff burned through the engine okay, but as soon as things cooled it solidified and stuck the valves in the guides solid. I saw quite a rash of this when the oxygenated fuels were first introduced in the late 1990's. It seemed much more common in engines with good tight valve guides. It didn't seem to effect old worn engines as much.
Harris County (Houston) TX and a few other high pollution cities were the only ones to get this re-blended fuel at that time. It didn't seem to be a problem with regular unleaded gas. It is my theory that what ever additive they added reacted with the old fuel and caused it to liquefy. That's my story and I'm sticking to it
I thought you might enjoy the following photos. BTW as of the last time I was there, this was my favorite O'Quinn Duesenberg.




:D

ordinarily I would agree, but the entire intakes manifold, head ports, carb, etc was coated in a black plastic like substance. It could be melted out with a heat gun or would come out with a strong solvent.

Well, I was running the Clear Vision this morning. With all those cars and only two guys working on them I haven't been able to work on it as much as I would have liked.

I haven't set the timing yet, nor have I filled it with water, but I ran it a few minutes. It has a little tic, but I don't know if I screwed up the valves adjustment or if it just needs to saturate itself with oil. I'll tell the folks at Meadowbrook that I left my watch in it by mistake.

It fired right up, and idled more smoothly than it did before. It was holding about 60psi oil pressure cold and at a slightly faster than normal idle.

I feel the need to toot the horn of Brian Joseph once more. I need valve adjusting discs, and his were on loan to California. He had the guy overnite them to me. I used them and overnited them to Brian. Is he a class act, or what? It has been my experience that over 95 per cent of the people involved in this hobby/industry are nice people.

For better, or for worse, the Clear Vision is on its way. The truck was almost virtually waiting for the car when I tightened the last bolt. I just eyeballed the distributor and carb into place, and it runs. I'll fine tune it when it returns. Wish us luck at the show.

Meadowbrook 2007 has come and gone, and we did fairly well. We took a first in class for early American motorcycles with a 1926 Indian four cylinder. We took best in class with a Packard Phaeton, and second in category with the Clear Vision.

I was proud of the Clear Vision. I ran and idled flawlessly going in, and for the long award ceremony, and it is on its way back. They had a special category for the Saoutchik and Murphy coachwork cars. The Acd Museum had a Murphy convertible sedan there, and I believe they had the Murphy bodied Cadillac. We had the Saoutchik bodied forty eight Cadillac convertible, and Brian Joseph had the Bucciali TAV2 there, which is a Saoutchik body.

It rained on and off in the morning, and then stayed cloudy and felt like air conditioning the rest of the day. The first show I ever bought a hat for, and the sun didn't come out.

For those of you who had an interest. The clear Vision idles more smoothly than it ever has, and all I have to do is adjust the valves one more time and set the distributor a little better.
