You would be wise to check it out carefully. See Gilly's response on a 722.6 thread
here.
I didn't say that they were all bad. My orginal post on this thread said that they all had the 3.5 liter engine that is known as the "rod bender," which is true. Then in my post today I said that all the original engines were suspect. Just like I would say that all 722.6 transmissions are suspect, but not all are bad.
