why oh why

A few years a go both Toyota Corrollas and Chevys (I think they were called Novas) were made on the same line at the Fremont plant. The Chevys were cheaper new and lost thier value quickly. Savy consumers could pick up a good Corrolla with a Chevy badge at a bargain. -
every seal you can get to. The oil pump o ring and crank especially. Check valve clearance. If your money is still good rear seal and change the plastic seperator for a metal one. Water pump and tensioner if you have the money. You will probably find something else too, but if it is a manual tranny this is a good time to do the clutch. This is what I had done on mine, it does not leak and I hope it stays in the car till the rings wear out.

on my BMW and the last Mercedes I rebuilt this was a no no. Bolts stretch to get thier holding power and a lot of the new ones are only supposed to stretch once. This is sort of like when you stretch an elastic band. The head bolt is always pulling the head down at a predetermined pressure. Bolts used to come loose more because gaskets would compress, dirt in the holes would come loose, or the lesser quality of the bolt steel would stretch. Heads often were off several times in the life of a car becuse you had to grind the valves regulary and decarbon. For these reasons checking the torque during a tune up was common. With a modern car the head often stays on for the life of the car.

a car with 108,000 can run. It uses a regular small amount of oil and a bit more when driven hard or on trips. There is a reason the manual tells you to check the oil with each fill up on gas. Good thing you checked when you did, but there may be nothing really wrong with a 97 that used that much oil in two months other than being a bit old.

If it were mine I'd tear off the heads and see what I had in there. I have also heard of a seized cam and if I recall when they got that engine down it was determined to be because of low oil pressure due to an oil pump seal. Trust me that it is truly frustrating to go to a lot of trouble and find out later you wasted all that time.
