Friends of mine have a 96-98(?) avalon, with 79,000 miles. It is using 3 qts of oil every 250 miles. There is no oil on the ground and there is no oil in the anti-freeze. Has there been a problem with the avalons? If not what might it be?
Thanks, Ron

PCV valve stuck. If not I would say rings/valve seals

if your PCV valve is stuck solid, and you're still driving it around, your vavle train, oil pan and your pistons will be covered with a thick oil like sludge, and your combustion chamber will have a thick carbon buildup. in addition to that, your gasket and valve seals will deteriorate. The PCV system is designed to remove crankcase fumes and pressure from the crankcase. these fumes can cause rapid sludging of the oil and deterioration of rubber parts. a faulty PCV valve can cause all this. if you do find it to be the PCV system, make sure you also have the engine resealed and new valve stem seals installed along with the new PCV valve and hose.

Is the car have lots of smoke out the back??? if it uses 3qts of oil every 250 mi. it must be burning. possible not draining back fast enough.let it sit over nite and check dip stick first thing before starting carand see where the the oil is on the dip stick...

hi im new to the forum...

thing is same thing was happening to my 95 129,000 miles avlaon.(which recently died) took it to the shop and they said the engine is done becuase of too many deposits. The car died while i was driving and wouldnt start again. I checked the dip stick and there was oil...not much but there was some...is that what killed the engine?

There was a previous incident with the same problem when my mom got sidelined also because of oil leakage. Fixed it but they said it wouldnt last long...

Whats going on??? I thought toyotas were supposed to last =(

pull your front valve cover you will prob.find that the engin is sludged. it will have to be cleaned and new valve seals installed.

take it to toyota they will do it for free

u better have some oil change reciets.
