Compression help one cylinder is low
As some of you may remember, in May I bought a '76 TR6 to restore. Over the last few weeks I've rebuilt the carbs, and drained and cleaned the gas tank.
I finally started it up a few days ago and have been trying to tune it as well as get the carbs set correctly. This morning, I had the car running while making some adjustments and heard a noise coming from the engine that you know when you hear it, its not good. It didn't make the banging sound continuously, but it did it every once in a while. I pulled the plugs and did a compression test and I don't like what I found so I'm looking for advice as to which way to proceed.
Here's the compression results (dry):
1=110 2=100 3=45 4=100 5=105 6=110
Obviously #3 has a problem. I added some oil to #3 cylinder and redid the test and this time it only came up to 60 lbs.
What is the best way to determine if its the valves or rings? If it is broken rings in #3 then whats to best way to proceed?
Thanks for any help.
