A year ago I had my 364 Nailhead rebuilt and hired a garage to install it back in my 58 Buick which has a Dynaflow transmission.
Saturday, on my way to a show, i heard a loud knocking noise under the car and pulled over. I turned the car off. When I went to start the car again I didn't get so much as a sound from the starter. I had power but nothing was moving. It took me jumping the starter relay (not the solenoid) from the positive battery cable to get it to engage again and finally start. This noise was intermittent ever since, but I also noticed a metallic grinding sound (like a circular saw) when i hit about 30mph. When I release from the gas and re-engage it would go away. I thought the starter was engaging while the engine was running.
I brought my Buick to the shop today to see what was making all the noise . They pulled the flexplate cover and discovered that one of the bolts that holds the flexplate to the torque converter had snapped in half and the remaining two bolts were loose. Right now they are trying to get part of the broken one out of the threads. Can someone please help me understand how this could happen so it never happens again.
Could this problem have caused the starter to temporarily fail? I can't wrap my head around how this could happen considering it was re-attached to the tranny a year ago and driven a dozen times since. I could understand if it had been on the car for years and the bolts wore out, but not a fresh install. Very frustrating.
