Hi everyone--just discovered this forum and signed up. I'm a regular on IH8MUD and Yotatech, and now I'm here. Can't get enough Toyota.
Have a question: Anyone know what would cause oil pan bolts to loosen 5000 miles after a thorough, professional rebuild by a highly thought-of engine shop? Engine is 3VZE in 94 4-runner with auto. I was searching for a large oil leak when I discovered the two studs at the rear stripped and all the bolts barely finger tight. As far as I know the vehicle has not been mistreated or overheated. Any ideas?
Thanks!
Jim
