2000 Acura Integra 4 cyl Front Wheel Drive Manual 107000 miles
my car is an 2000 acura integra ls. I bought it about 3 months ago and it was fine. My wife is driving the car and all the oil got burned up. And we did an oil change and I notice that it burn oil faster now. It only goes about 500 miles before we have to fill up again. And we even put thicker oil in there. And in the morning, the first start up of the day, it smokes for a little while and than it goes away. And this only happens in the first start up of the day then its fine. Would you guys know whats wrong?
What you are describing is classic valve stem & valve guide wear. There are small seals on the valves that restrict oil from entering the manifolds. When these seals and stems deteriorate hot thin oil will by pass the seals and a little will enter the exhaust manifold and the inlet manifold over night. When you start up this will show up as a plume of bluish smoke that will normally clear quickly. There will be a small on going oil consumption through there seals during driving but normally in such small concentrations that it is not readily visible, if it is there is a bigger problem, (rings) also involved. There is no short cut repair, I feel that the previous owner has use a temp stop smoke additive (this swells the seals in an attempt to stop oil passing) but this can do more harm than good in the long term. Best get a mechanic to do a comp test and get an engine vacuum reading this will give them a better understanding as to what is going on internally.
