the car seems to only burn oil when i start the car up after sitting anywhere from 30 mins to a few hours. when it sits overnight most of the time it doesnt. it may burn just a little bit of oil in the high rpms (5k) but not sure. i put one qt of oil every 700 miles or so. could it just be worn out rings, or something else that i could check?

it could be bad valve guide seals if it seems to burn oil only on startup; i doubt its rings if only on startup

just curious, but how do you determine that it burns oil only on start up?

Grey/white puffs of smoke on cold start.

so the problem could be in the top end? that would be great im on a limited budget it would be better for me to put new heads and cam instead of having the entire block rebuilt. but is it worth the risk?
