98 gs-r with 120 000km. The car is burning alot of oil under heavy acceleration, like i can go through half a litre in 2 days, but if i don't vtec oil consumption is fine. I've checked the tail pipe everytime i kick it, no blue or black smoke come out at all. I look under the oil pan, seem to be a bit of oil hanging on the drain bolt, but its not like dripping hard or anything. When i replaced the spark plugs, i notice there was fresh clean oil on one of spark plug in one cyclinder. THe car is fully tuned up. Could it be a bad seal??

 

I would replace the spark plug seals, the ones under the valve cover, and try using a better quality high mileage oil, and perhaps adding an additive such as Lucas oil treatment to aid in stop oil from burning.

Hope this helps.

im actually using mobil 1 10W40. iwill check the spark plug for oil agian.

 

my guess is that the valve seals are toast

 

I'd just take it easy on the pedal. Don't accelerate heavily and you should have no problems
