oil burning smoke at start-up

[Black Pearl 90]

I have a 1990 Accord EX coupe w/181,000 miles on it.the problem is after its been sittin a while like overnite it burns oil when first starting and continues to do so for about a minute or more then goes away.I have just replaced the valve guide oil seals a week ago and this still has not made the problem go away.Where else could oil be getting down into the valve and or combustion chambers to heat up and burn off?could it be bad ring(s)?any help would be appreciated.Thanks!

if valve seals are good then its probably rings. possibly head gasket but more likely rings.

I would say rings also. Once the engine is warmed up the metals expands, causing the rings to "seal" better then they are when the engine is cold.

compression test f22a4

I did a compression test to determine why my Accord is burning so much oil at start-up.The results were 1st cylinder-161psi--2nd cylinder-90psi--3rd cylinder-110psi--4th cylinder-157psi.After adding oil to second cylinder then repeating the test it was 159psi,and the third on a repeat with some oil was around the same.Even though rings are toast in cylinders 2and3 the engine runs and idles really well and has still got a lot "get up and go" for being way below standards for compression. The car has just passed smog 3 days ago,but was borderline for failing on the HC's at idle.

How can an headgasket cause oil to burn?


Try some thicker oil to temporarily resolve the issue but regardless its going to need new rings.

grade of oil

i like the idea of the thicker oil for a temp solution.It may also reduce the amount of blue smoke that blankets my neighbors house when starting it in the morning.Im planning on buying a low mileage engine from Attarco inc. when i get my tax return in Jan or Feb,rather than mess with same motor.What grade of oil would be best for the time being?

Possibly 10w-40,maybe even a little bit thicker. Just give it a try.
Im surprised replacing the valve seals didnt fix it.
