My wife car is burning oil what can she do to stop it change the head gasket?

changing the head gasket will not stop that problem, however the rings and/or the valve stem seals could be at fault. every engine out there burns oil. it is part of life and nothing that can be done about it. if you are not happy wit the rate of consumption there is a few things that you can do. first off go to a little heavier oil, that is all it takes some times. also there is now an oil for this situation, the higher mileage oil can help to return the seals to there original shape and help them become more flexible again. it is not a cure all though. most manufactures agree that roughly a quart every 3000 mile is normal. if you ask me if it does not happen, at that point i would worry.My wife car is burning oil what can she do to stop it change the head gasket?
There are too many answers for this question. How many quarts of oil is your wife's car using per 1000 miles of driving? Believe it or not, 1 quart per 1000 miles is considered normal although for late model cars this is rare. If sludge is built up in the valve cover(s) over the top of the cylinder head and on some engines this can be checked by removing the oil filer cap and looking into to the filler pipe area. If you see oil (like water not draining in the bath tub), then the cylinder head drain holes are blocked and need to be opened. The PCV system can also be blocked sucking oil under extra pressure.My wife car is burning oil what can she do to stop it change the head gasket?
do this first ! take the valve pans off and see if the drain holes are opened up. if they are clogged then oil can run down pass the valve seals and get on the valves. i fix a car awhile back and that what was wrong with it.
you did not mention the make or year of car. or how many miles on it. so we would assume that the car is old. you need another car or it is time for an overhaul.
Stop driving it.
