I have a 1948 Continental with a V12. Just bought it and last weekend took it out for it's first club cruise. 40 Miles to a nearby town. I felt confident since the car had a ground up restoration including engine and transmission rebuild 14 years ago and less than 2000 miles on the car since. Well my gauges didn't work, oil always showed 50 pounds, fuel always empty, temp, always maxed out and amps at zero movement, so when the oil gauge dropped to zero and then bounced around, I thought nothing of it... until the drive home. Engine clicking, turned into a heavy thumping knock. I made it home and the engine does run, but it's not sounding good. I did a compression test and My readings are as follows 105 90 95 91 100 98 105 97 90 91 95 105 The manual says pressure should be between 105 and 125... so I'm not looking great. I do think my car was warm, but i only ran it for 10 minutes before running the test. I added oil to three cylinders to do a wet test and the scores came up to 100, 101, and 100 for previous scores in the 90s. So it looks like overall my compression is low, I suspect the sounds aren't from just a cylinder but are valve and perhaps lifters, etc. I'm considering having the engine rebuilt, looking for a shop that really knows these engines and will not cut corners. I want it running better than new. Any thoughts out there?
