Hi everybody,
I have a Corolla with 235,000 miles on it that burns a quart of 5w-30 every 300-500 miles. It has good compression in all cylinders and so I assumed it was the valve guide seals/lifters and that if I rebuilt the head I'd get good results. Nope. Just spent $1650 and it still burns about the same amount of oil. Looks like I'm going to eventually rebuild the block too. Probably the oil rings eh? I just put Castrol 10w40 in it as prescribed by the machine shop to slow the burning. Any helpful thoughts?
