[QUOTE="Dean Hedin, post: 1029658, member: 57230"] Yes, the 4.0L went from around 165hp to 210hp with the addition of the overhead cam. Which is very respectable. But I probably would have been just as happy with some minor tweaks to the older OHV engine. They probably could have gotten it up to 185 or so if they bumped the compression to 9.6 like they did with the SOHC. I pulled my "deluxe" center console out of a 2001 Explorer Sport at a junkyard. It had "timing chain bad" waxed on the inside of the windshield. Sad. Nothing wrong with it otherwise. I just want to emphasize..Very few local shop mechanics will go deep into a high mileage engine. It's just too time consuming and risky and they don't have the specialized tools. If they are pulling it, its just easier to get a motor from a re-manufacturer. If something goes wrong with it the costs to fix are shared between the mechanic and motor re-manufacturer. Timing chain guides & parts is what - something like $400?... and now add in the mechanics labor (motor in/out AND futzing with the guides)? Where we at? $1800-2000? and we are putting the 160k motor back in? Forget it. Fork up the extra $1000 and put the reman motor in. Now, if you are doing the work yourself..and your on a budget..that is a different story. [/QUOTE]
