ok i finally am getting around to fixing the bad valve in my 260e and im waiting on the tool to take my head bolts off in the mean time i thought id ask if i should get my head inspected at a machine shop to check if its warped when my car was running the oil didnt mix into the coolant and as far as i know it didnt use up to much oil the car has 122000 miles on it and the only known issue was that the fith cylinder was getting zero compression any sugestions would be appreciated thanx and o ya if theres any other way of taking the head bolts off without buying that 30 dollar special torx bit let me know thanx
