My car is burning oil just wondering if anybody could here anything that could possibly be wrong with it. My guess is that the oil control rings are stuck with carbon because compression is still ok. Any opinions agreeing or disagreeing would be helpful thanks.

What evidence do you have of your engine burning oil? What about leaks? Have you looked for them?

 

I am wondering the same. How are you certain your burning oil?

I can't tell exactly from the video but it sounds like a valve sticking also judging by the exhaust sound.

Positive i'm burning oil. I go through a court every 500-800 miles so it's pretty significant. It really starts to show smoke over 4000 rpms. No leaks at all either. Got under the car and there is not a drop of oil.

 

Might come as a shock to you and many others, but i have done this myself a few times. Go buy a lead substitute/additive for the fuel. Use as directed. The lead helps to breakup carbon and re seat valves and rings. I'm honestly not entirely sure how it works, but i have done it on three vehicles. Two being carburated, and one being my eg.

It won't stop oil burning if it's bad valve stem seals or head gasket. I have actually done this. Same with gas/quality/mileage, etc. my friends truck starts to smoke slightly every 2,000 miles or so, he runs the lead substitute again through one tank and smoke goes away. Now it's obviously not a permanent fix, but it does work. Might take a few tanks of the stuff (all three vehicles i did were different) and don't be afraid to drive it hard. Driving with the engine At higher rpms also prevents carbon buildup and breaks up carbon deposits already in the engine. The higher rpms and internal engine heat/friction helps keeps rings lose and clean.

I wouldn't put much stock in this theory. I almost never push my engine above 4000 rpm. It simply isn't necessary for normal driving. I have a 91 Accord with about 301K miles on it and I simply don't drive that way, which is undoubtedly a big factor in getting that many miles on it and yet no oil burning.

 

Well i just pulled the sparkplugs and there is a definite buildup of carbon on the piston heads so i am assuming it would be in the rings as well. I am considering doing a pistonn soak with berryman's chem dip as the MMO has done nothing.

 

Also the plugs have oil on them and i just changed them under 1000 miles ago.

 

It's not really much of a theory. My cd5 when i first got it was driven at very low rpms never brought even close to red line. When i changed the plugs i looked at the pistons and they had some pretty bad carbon buildup on them as well as the spark plugs. When i changed the had 100k later there was no carbon to speak of. It also helps that i use good quality fuels.

check the valve seals if that there will be know sign of oil leaks just burn

 

Do the plugs have oil on the top part or the electrode? And do the plug wires have oil on them?
