Rebuild Time......Hint, Tip and Words of Wisdom

I just noticed my car burned 3/4 of a quart of oil in the last 800 miles. The car was consistently burning about a quart every 2000 miles. If this is not some sort of fluke, I imagine a top end rebuild is in order. The car has only 70k miles on it, is this too early? Are there any other things it could be other than worn valve guides? I am planning on keeping this car for a long time if not forever and want to get it in order to run another 70k miles. Any hints, tips or words of wisdom invovling the rebuild and things to do while the engine is out? Thanks.

I think it would be well worth the money to have the compression and leakdown checked first; the rule of thumb is 1000 miles per quart is still okay. If the car is running well and still pulling strong, I'd be disinclined to mess with it. Have you changed brands of oil? Pulled the undertray to see if you have a leak? Revved it up to 5000 rpms while driving, let it fall down to 2000 or so with engine braking, then floored it and looked behind you to see if it's smoking? Lots of variables here. Bruce Anderson's advice on worn valve guides was to wait until the car tells you it wants to be rebuilt ... it will start drinking oil and smoking and fouling its plugs and then you know.

No leaks as the engine tray is off. The car runs fine, no change in performance that I have noticed. I will check for smoke but as far as I know it is fine. thanks for the advice.

I'd drive her a lot more and would take more accurate readings on oil consumption. I'd also keep a similar log on fuel consumption and 'driving behavior' e.g. acceleration (or lack of), etc.
I'm just trying to save u some $.

Don't forget - at this time of year (approaching winter or immersed in it) the car when fully warmed up will be a t a lower temp than in the summer. This typically translates into a lower oil level on the gage or stick making it look like you've burned some when maybe you haven't.
