It makes me happy when this happens, plus all 8 spark plugs came out just like they went in 9 years ago. This is the engine from the Navigator we purchased one year old and got ran into last year. This engine has had oil changes every 5000 miles with 5w-20 synthetic oil and has been run on premium fuel since I purchased it. There is zero wear on the internal components and never used any oil. This engine has 240,000 miles on it and I am resealing it, tuning it, replacing all the exhaust studs, new water pump and installing it in my 06 2wd Navigator. The Navigator engine is making timing chain rattles when starting.
