Thanks everyone. Here's the latest:
It was originally a chain-drive lower end. I converted it to
gear-drive, using stock Guzzi gears. My first thought was oil pump,
since this one has 80,000 miles on it since I put it on the bike and
an untold number from its first owner, so I changed back to chain drive
and another 9,000-mile pump. I hate the whirring noise of the Valtek
tensioner, but I don't have any more time for messing with it right now.
Last fall, when I converted to 950-cc Nikasil, I also converted to run
an oil filter. Two days ago I added a sump spacer and tried it with and
without another quart of oil. This helped, bringing me up to 45 psi and
47 psi, respectively. The base problem still remains, though: it's
heating up the oil too much. On a 70-degree day at a steady 75 mph, the
oil heats up to 110 degrees C. That's way too hot. (BTW, you can add a
spacer to non-filter twins. Patrick Hayes had one on his Eldo, and I
had another I got in a pile of parts that I passed on to another
Seattle Eldo rider. I can't remember what company made them. Also, you
can add the Escher filter conversion, which includes a sump spacer.)
I ran a leakdown test yesterday. Results were 10 percent right (with
predominent leakage through the exhaust valve) and 5 percent right. 5
percent is darn good. 10 percent is not. I'm gonna lap the valves,
hopefully today. I still don't see how that valve leakage would
contribute to the heat problem, but a mechanic said it could because
the whole engine has to work harder to get the power to run those
speeds. We'll see.
Anyway, I think I'm just gonna ignore the gauges and go to the National
anyway, but maybe at slower speeds than I'm used to running.

This is still a non-oil-filter lower end? I assume you would add the spacer but keep the oil at the same level in relation to the pickup? Is yours a gear or chain model? On the gear models, I have seen several oil pumps with galled gears, and galled holes in the block where the pump shaft runs. 73 Eldo 78 T3/949 ----------------------------------------------------------- Apply now for a No-Annual-Fee Discover� Platinum Card 0% Intro APR*, No Annual Fee, Up to 2% Cashback Bonus� award* Start Saving Today � APPLY NOW!
