I have a 1994 nissan sentra 124,000 and it is using a lot of oil. It is is not going on the ground. There is blue smoke coming out of the tailpipe. Is there an easy fix? The car seems to run fine. Also there is a hose coming from the transmition that doesn't seem to go to anything. Is that a vent?

the hose is probably a vent. the blue smoke you're indicating is that your car is burning oil. more than likely the piston rings are worn or the valve seals. the only way to fix the problem is rebuild the motor or replace it.

Hi there,

If you notice blue smote on start up, good chanch that the valve stems and or guides are worn, smoking all the time normally indicates worn or broken oil control rings, don't waste your money on fixes in a bottle, they don't work a re build or change over is your only option.

Suggested Repair

Rebuild or replace the engine. Blue smoke means the engine is burning oil from worn piston rings, valve seals, or guides; bottle additives will not fix it. The unconnected transmission hose is likely a vent.

The owner of a 1994 Nissan Sentra reports high oil use, blue tailpipe smoke, and no oil on the ground, plus a transmission hose that appears unconnected. Experts say the hose is likely a vent and the smoke indicates oil burning from worn rings, valve seals, or guides. They recommend an engine rebuild or replacement rather than additive treatments.
