No compression in one cell ender need to be pulled out and replace only that one. Then put back running. How much would it cost?

We don't get involved with costs here because there's way too many variables. We don't even know what's wrong. What you're asking doesn't make sense. The cause of compression loss has to be diagnosed to know how to proceed. Burned valves are the most common cause but there could be a worn lobe on the camshaft, broken rocker arm, etc. Some of those things can be fixed in a couple of hours. Valve problems require removing the cylinder head and many hours.

THERE IS THAT POSSIBILITY THAT YOU REMOVE THE VALVE COVER AND FIND A VALVE STUCK IN THE OPEN POSITION

PENETRATING OIL AND GENTLE TAPPING USING A BRASS DRIFT MIGHT UN-STICK IT

I HAVE ALSO USED THE OLD TRADITIONAL METHOD OF "AUTOMATIC TRANNY JUICE" DOWN THE CARB WHILE KEEPING IT RUNNING A 1500-2000 RPM, WITH REVVING ALONG THE WAY - THERE WILL BE A MONSTROUS SMOKE SCREEN WHEN YOU DO THIS!

KEEP US POSTED ON PROGRESS
