Sounds to me like you have one of the rings going bad. If it uses alot of oil, she needs an overhaul.

"Cheap" "low quality" oil and oil that is "to thin" (such as 5W oil) will make even a good engine smoke some. You might try a good synthetic 20w-50 oil if the engine is well worn. Good Luck, Gordon

Denny mentioned plugs. What are they like? If you are burning enough oil to see blue smoke, you should be fouling plugs too. Then you could look at the actual crankcase oil level. If it is too high, you could get more oil up on the cylinder walls than the oil rings can push back down. One more thing - how is your valve train oil drain up in the head? If it is plugged, you get more oil up there than the valve seals can handle.

borrow a compression tester, after the engine is warmed up check the compression in each cylinder.
I your compression is good, the problem is your valve seals, otherwise it's your rings.

Most of the time smoke "BLUE" is a sign of bad piston rings. What it is that more oil than normal is getting past the rings. AC

If it might be oil getting past the intake guides, I use Ford type " Umbrella " seals... Requires no machining, and cost very little... I don't remember if AC uses any stem seal, or not, but I prefer to use the umberella seals...
just to be sure... Any possible chance you have diluted oil...???

Denny pretty well covers it. Blue smoke would pretty much indicate oil burning, black would be too rich a mixture. Dave

I'd lean to the valve guides. If the valve stem is loose, oil can slide right down the stem. The intake stroke can help pull it in. Bad rings are also a possibility. Oil drains off the cylinder wall when the engine is turned off. Once it is started, the oil ring is supposed to take excess oil from the cylinder wall. A broken or cracked oil ring can act like that as well. Can you determine if it is all cylinders or just one (check the plugs to see if one is oil wet and the others dry)? If it is only one cylinder, it may be a cracked or broken oil ring. Cracked rings need to be changed immediately to avoid permanent cylinder damage.
