absolutley , ambulance for some reason the last 6 i have had in i found the high pressure leak on the passengers side , in the oil rail the dummy plug at the front has two o-rings on it , the bottom o-ring is usually blown out

9 hours to pull valve covers sounds like WAY to manyhours for that job. not fun, but should not take 9 hours, maybe for removal and replacement, but not just removal!
