I've only had one toyota - a Corolla - it is the only vehicle I have ever seen to have the engine valves split open on two different cylinders. I had a 1985 Chevvy S10 Blazer that the transmission (auto) blew out at 70k miles, then the motor at 105k. I have a 1996 Chevvy Tahoe where the transmission failed and was replaced at 48k miles. My 1991 Ford Explorer is still running on the original motor and transmission (auto) at 151k miles and has never rolled over. It uses a quart of oil in 3,000 miles. I now have a 2001 Chevvy Tahoe, I have no idea how long it will go without serious problems.
