I'm back after a few months off the list. If you remember from this
summer, my oil pressure relief valve got stuck in the block. I had to
remove the engine and drill into the valve and pry it out with a
crowbar.
Well now it's stuck again. I'm afraid the bore in the block is messed
up, like like it's scored or widened. One day I was driving the B (76)
to school and taking off from a red light. Then the pressure, instead
of relieving itself at 75psi, shot to about 100 when I took off, and
stayed there at any rpms above 1500. I put put-ed home after class that
day (2000rpms in 4th, about 80psi) and the car hasn't moved since.
So I'm faced with a problem. I'm going to pull the engine again next
week when I get the car trailered home. Is there any way I can get an
oversized valve made, and have that part of my block bored?
This engine ran incredibly well both before the valve failed the first
time, and after I reassembled the engine. Great compression, and great
oil pressure. I don't really want to take the engine from my 74.5 GT
unless I have to, and I don't want to have to buy a used block. When I
took the head off of this one, there were no ridges at the tops of the
pistons, and very little wear on the bearings.
Any help is appreciated. I start working on the car Wednesday. Thanks!
