Default Blue smoke out exhaust

So when my 02 Saturn sits for a couple minutes and then you rev it up itíll go live a little puff of blue smoke. Is that likely oil control rings or valve seals? Is there any cheap remedies I can try or should I just let it go and live with it? Engine has 121,000 miles

Valve seals are not a common failure so that is oil bypassing the rings, probably all of them and it is not that unusual. Might even oil being sucked into the engine through the PCV valve which is not uncommon either. There is no fix in a can for this either.

Would a piston soak with marvel help at all?

Blue smoke stopped on my Chevy Avalanche directly after adding 32 oz of Lucas Oil Stop Leak, available at Walmart etc.

I did a piston soak with marvel last night the 1 cylinder drained down over night the other still have fluid. I figured Iíd let it sit another day since I donít need it.

The one that drained down is your blue smoke.

How do you know that? Wouldnít the one that drained be less coke up and clogged up? Or did it drain because the rings arenít sealing as well?

Compression rings hold the fluid, oil rings scrape off excess oil. Rapid drain down points at compression rings as oil rings have little to nothing to do with compression. Don't bother running a compression check as you will never see this small bypass leakage.

All things being equal between the cylinder fill with fluid the one that drains first has the highest leakage. As you are seeing that blue cloud you could change the brand of oil you are using and it might go away. FYI a full synthetic is much harder to burn.

What makes a full synthetic harder to burn? Wonít it leak past the rings just the same?

Because it is a plastic and not a basic hydrocarbon. High quality gp4 synthetic does not easily carbonize in an engine so it just ends up going out the tailpipe with no gray cloud.

Could be both. These cars lack drain back holes in the pistons, which starts the consumption process. Poor maintenance or excessively low oil levels, combined with extended OCIs will trash the valve stem seals FAST

Full synthetics are more resistant to oxidation and have better thermal resistance to breaking down.

The oil on the cylinder walls carbonizes the rings from excessive heat. Higher resistance to thermal breakdown will lead to slightly lower oil consumption.

Actually the type of OEM valve seals tend to last long after the oil consumption is being measured in quarts/mile. These are not like your father's oil seals.

Well I used a bottle of marvel mystery oil and a can of b12 chem tool to piston soak for a couple of days. And today I got it all cleaned up and running again. No more blue smoke at all. Really didnít expect that! I did a compression test to while I was there they were all 210-215 so sounds like the engine is strong.

Start using a top quality full synthetic 5w-30 oil.
