A few years back I purchased a 1982 Ford econoline club wagon. 2wd with a 351 windsor. 38k miles original, nice rig
Only major issue I noted was at times it would puke oil out the rms. 2 piece rms being roughly 40 years old. I know what to do now
One summer I decided to pull the motor and give it a reseal, not down to head gaskets but everything else was inspected/replaced
Now I'd never gone this far in depth with a ford engine but I figured I can get by with my knowledge, an mcm vintage manual for specs and local/online part houses. It worked out great
After removing the oil pan and getting eyes on the rms cap/housing I had no idea what I was looking for. When I removed the cap I saw an empty groove where the rms should be. Ford sent this block out with no rms in place, Friday motor
Installed a new rms with anaerobic red silicone and never lost a drop out of the rms again.
