My 95 Cougar with the 4.6L V8 burns a lot of oil. Maybe 1qt per 1000 miles. The odometer has stopped, but my guess it has about 110,000 miles. I occasionally see a puff of smoke when I accelerate after sitting at a stop light but have never seen a massive cloud. I often sit with the AC on waiting in a parking lot for my son. After a few minutes of idling, I start to see and smell burning oil. The engine starts and runs great, even idling. There have been no codes of any type. I have not calculated MPG, but I do not notice excessive fuel use. The car sits in the garage over the winter.

A friend suggested a clogged air filter may be the problem. I will get a new one today, but doubt it will correct the problem.

I bought the car brand new, so it has sentimental value. However, the idea a spending several thousand dollars on a rebuild sounds like a poor investment.

Thanks for any advice.

I agree with Logan. The early 4.6 npi motors were notorious for their valve seals wearing out prematurely causing excess oil consumption.

Thanks for the tip. Sounds a lot better than rebuilding the engine. Any thoughts about $$$. I can perform some basic engine work, but this would be over my head.

I honestly dont know how much it would be to replace the valve stem seals by themselves. Maybe call around to local shops and get some quotes.
