compression test on my BB
I did a compression test on my car today,and 7 cylinders were between 175-200 psi. One cylinder was 65psi. I added a couple of squirts of oil and it only came up to 75psi. What do you think, cracked rings mabe? Car is smoking on that side. thanks Jeff

Re: compression test on my BB (jeff batchelor)
Next you need to do a leakdown test to see what's leaking..
Could be a valve, indicated by air leaking through the carb or the exhaust..
If air leaks out the oil filler it's a ring.
Good luck
