Hi....need some opinions on a car I'm looking at.

Compression #'s are good all the way across, within 5 lbs of each other.

Leak down #'s are off. 3 cylinders at 90% to 95%, 3 cylinders at 60% to 70%.

Owner is going to have a valve adjustment done to see if that brings the numbers up.

But... just for my edification, it's usually rings or valves at this point right?

So, if the numbers don't come up...it means a "top end". How much? $4k?

Any input?

thanks,
Eric
