David, can't help you with your questions however I had a similar
experience; the year was 1976 and I was driving a TR3A with a
transplanted TR6 engine on a Los Angles freeway.
It was dark outside and I had never been on more than a 2 perhaps 3
lane highway before and when I checked my instrument panel, the oil
pressure indicate 0 psi
Managed to get over to the side of the road and when I checked the
Turns out I had used some rubber surgical tubing to make the connection
from the metal oil pressure line to the engine block and the barbed
fitting had finally let go after a few thousand miles.
A state trooper drove me down to the nearest service station and I
purchased 4 quarts of oil and received a ride back to the car from one
of the employees. Girlfriend and contents were still in the car.
After adding the oil and starting the engine, there would be a brief
knocking. At low rpm, I did not hear any other strange noises. After
reconnecting the line, the oil pressure was down to about 10 psi
I added a couple of cans of STP oil additive which was similar to the
consistency of honey at 0 F. This raised the oil pressure by about 5
psi and I was able to drive the car back to Canada (2000 Miles) at
about 40 mph. (the tranny had O/D)
Was a very long trip back, a 12 hour day netted about 350 miles with a
few sight seeing stops along the coastal route.
From what I recall, several mechanical issues on this trip prior to the
oil loss. - loose alternator connection on gauge, - brake fluid leak at
master cylinder, -water pump replacement, and torn diaphragm on one carbs.
The torn diaphragm occurred on the way from Vegas to LA and caused the
car to run lean and the added heat in the exhaust system resulted in
some carpet melting/burning behind the drivers seat.
The first sign of the carpet meltdown was a sweet odor which we thought
was desert air and later, smoke came out from under the dash making me
think the prince of darkness was at it.
Oh yeah, then there was the rainstorm somewhere around Yellowstone
National Park which proved that the car was not waterproof. Water came
in everywhere which probably explains why floor pans require replacement.
The rain was a bit of a relief from the bytes of the mosquito swarm that
feasted when I stopped to put the top up and and install the side curtains.
I am thinking about a Spitfire trip from Vancouver to Phoenix in the
Spring but not so sure I could handle as many issues at this point in my
life. Perhaps I will trailer the car.
