Phil---To satisfy your curiosity about how much #6 (sparkplug wire) contributes
to your engine, pull it off and drive the car, if necessary.
On the oil pressure: 35lb. is lower than it should be, even tho you had the
engine oil good and warm with the extended highway cruise. It should be over
50psi, with a "tight" engine running closer to 70 lb.of pressure at the
3,000rpm mark.
Sounds like your TR is a looker, tho!

Well, the TR6 ran like a champ for the 600 mile roundtrip down to southwest
Indiana and back this weekend.
The only notable occurrence was the #6 plug wire somehow popped off the
distributor on the trip down. Not sure when it happened but I noticed it when
checking the oil on Friday after the drive down there. Strangely enough the
car wasn't running bad on the trip down and didn't seem any different after I
reconnected the #6 plug. I halfway wonder if it got disconnected when I
checked the oil but it seems unlikely that you'd tear off a plug wire on the
back of the engine while checking the oil :)
Got tons of compliments on the car. One guy even went to far as to stop at
the cabin we were staying in and knock on the door to ask about the car. One
of the other guys I was down there with drives a white '70 Mustang
Convertible. Very pretty car. He was surprised by how many comments I get on
the car because, according to him, nobody ever really asks him about his
Mustang.
The only remaining question I have concerns oil pressure. I run the engine
with 20W50 oil (which is pretty heavy) and the engine usually maintains about
50PSI at 3000 RPM when warm. Normally I just tool around town rarely driving
more than 50MPH except for the occasional trip down the highway for 15 or 20
minutes. However, on the roadtrip, after about an hour of 70MPH highway
driving the oil pressure was down to something closer to 35PSI. It stayed
there for the entire 4 hour highway drive. Getting off the highway and
letting the engine return to idle the pressure dropped pretty low (down to
about 10PSI at idle). Is it normal for the engine to maintain pressure at
those levels when running a long time at a reasonably high RPM?
