Late 2013 we bought a 2001 Ranger Edge with V6; ODO=87K. Seven months and 1500 miles later the engine died while my wife was 60 miles from home. Ford dealer #1 did the diagnosis and came up with a pretty long list of issues and a high $ repair estimate. Since the truck was pretty nice otherwise, we decided to have the dealer replace the engine with a Ford reman long block.

When the work was completed I test drove the truck for a few blocks and thought the engine sounded a little rough. The tech listened and could detect nothing.

A few months and 2500 miles later the truck went back to the same dealer for an oil change. I mentioned my concern about the engine noise and the tech drove it and commented on the work order “has a little push rod noise due to oil viscosity is gone”. They completed the oil change and fixed another small issue.

The sound I'm hearing is hard to describe. Best I can come up with is it sounds kind of "growly" and the sound is most noticeable while under load and at low to mid RPMs.

My feeling that something was amiss (sorry) remained so I had a friend with a SnapOn Solus Ultra run an scan. He found that cyl #5 was misfiring almost continuously. He also noted that Node 6, Test 56 fails (whatever that is) and detected erratic fuel pressure, indication of possible PCV valve problem and possible failing cam synchro.

BTW, I thought that continuous misfire would result in CEL but it isn't on.

The engine has a 3 yr. warranty and I've found a Ford dealer that is closer to home so it's going in today.

Here's my question (finally!): if cyl #5 has been misfiring for 2500 miles should I be concerned about excessive wear of cylinder walls and rings due to raw fuel?

I think for now you should be more worried about whether or not Ford replaced the cam sync when they replaced the block.

Interesting; the cam synchro was called out as a failing item on the original estimate and the replacement part was listed as well. But on the WO for the engine replacement, I don't see it. Could this part have been included with the reman long block?

Whatever is ultimately done to fix the misfire, assuming that is what I'm hearing, I still have concerns about the 2500 miles with the effects of the raw fuel in cyl #5. Any thought would be appreciated.

I do not believe they would include the cam sync.

My reman long block didn't come with a cam synch, but I didn't buy it from Ford.

I seriously doubt it would come with one anyway, though. It was probably just the block and heads.

I will check with Ford tomorrow to make sure, but on this list http://www.prgmhq.com/RemanEngineKit...20Contents.pdf the engine I got is the 6006; maybe the cam synchro is included in "timing components"

Also, I'm still wondering about the effects of raw fuel in cyl #5 for 2500 miles. Any thoughts?

Thanks,
Wayne

Hmmm. I just got a call from Ford dealer #2 informing me that they had ordered a new long block to replace the one that was installed by Ford dealer #1. The Service Advisor didn't know what the tech had found with the old one but I'll find out. Hope the 2nd one is better than the first.
