The same thing happened to me years ago on a Pontiac Grand Prix. I would
bet that you have a bad fuel pump. There is a diaphragm that separates the
mechanical side of the pump from the gasoline side of the pump. This
diaphragm is probably leaking fuel into your block where the pump's lever
reaches into the block.

Subject: Sick TR6
I have a 1971 TR6 that is a "rolling restoration" and I have driven it more
this summer than in the past 4 years combined - and I love it!
Now my problem - the other day on the way home from work the engine started
to miss at about 4,000 rpm (I thought it was a fouled plug) so, I didn't
think much about it. During the same trip the brakes started to pull to
one side while braking. So, I put her up on the jack stands and a few days
later when the parts arrived, I did a four wheel brake job (the left rear
was leaking brake fluid - a lot). While the car was on the stands, I
noticed that the front carb was dripping some gas - we've had problems with
stuck float valves before - so once again I didn't think much about it. I
cleaned the plugs and started the car - in order to use the vacuum assisted
brakes for easier bleeding. After the car started, I noticed that the oil
pressure wouldn't go above 20 lbs. - this baby regularly gives me at least
50-60 lbs. - Oh, No!!! - I shut the engine off right away, and pulled the
dip stick to check the oil - the oil is now very, very thin and is diluted
with a large quantity of gasoline. I've worked on cars for 32 years and
never had this problem before. My first thought is a hanging intake valve?
The plan is to test the compression in all of the cylinders this weekend as
a starting point. Anyone else had this problem before? Any ideas are
welcome. Thanks in advance.
