168k 1997 honda civic dx:

I just replaced my valve seals and I am still consuming lots of oil. Is there anything I can place through the spark plug holes so that it dissolves the carbon? I have a gallon of LC20, I wonder if I can pour some in and let it sit on the rings. Maybe it's too thick.

Try something with lubrication such as LCD's LC20, 4-6 ounces in each cylinder.

Let it soak overnight and then turn crankshaft by hand.

Let it soak overnight again and repeat next day.

Before firing up, inspect each hole to make sure all liquid has run past the rings. If not suck it out.

Are you sure that it was done right? It's not difficult to damage or break these very delicate seals during installation. Also, if they aren't seated properly, they will pop out and then you have no seals.

I'm confident I did it right, just the way you described in your DIY, but I will check again soon, just to make sure they haven't come loose. Thanks.

I'm putting in like 2 quarts every 3000 miles. No external leaks. Could a headgasket leak oil into one of the cylinders? I have no coolant leaks.

How is it smoking? Usally smoking at idle = valve stem seals. Smoking under aceleration = rings.

I had no smoke, no drips, just lots of consumption on the highway... Did B-12 chemtool flush after other options didnt help. Added restore after that on a whim because lots of reports indicated it quiets lifter ticks. Both the tick and the consumption are gone!

Be careful speaking positively about Restore, it could get you in trouble around here. LOL

Yeah but for how long are they gone? Until you stop using the engine restore? Was it the b12 flush that cured it or the engine restore?

I cant say for sure. I wasnt intending to do a scientific study, just some last-ditch efforts after trying a few other things. Next step would be to live with it or to shell out money.

In all practicality, given that one item is like $3 (for a full bottle that you only use half of), and the other is maybe $10, I really dont care all that much, because application of both is so darn cheap. When I change out my oil and dont put anything in, then if/when I see changes, it may be telling...
