Re: my engine has a rod knock
Uh... Yeah, I was. Steve - How the heck did we suddenly end up on the opposite side of the fence? We were arguing the same point. Thanks for all that evidence by the way! That's some pretty darn good stuff! I am as sold on the reliability and engineering of the FEH as I could possibly be. In fact, I think your post has made me even more so.
Please re-read the past few days of posts and I think you'll see what I mean.

Re: my engine has a rod knock
This discussion reminds me of the Porsche EXPLODING rubber clutch episode back in the early eighties. Having had one myself, a '78 Targa, EXPLODED at only 38,000 miles, I was fully aware of the problem. But get anyone in the Porsche community, dealer, aftermarket shops included, to discuss the issue openly, NO WAY, Porsche would NEVER commit such a sin.
"Porsche can do no wrong..!"
Then in '83 Porsche dropped the rubber center clutch, admitted the reason, and suddenly the issue could be discussed, admitted, openly.

lol. well put. I think Bill should go run for office..again. i think Vernal Utah needs a dog catcher. He would tell cavemen they did the wheel all wrong and left out a rock then proceed to add one and tell them his rock wheel was superior. lol.

Re: my engine has a rod knock
One thing I've been wondering about.
Back in the early 2000's many of the people over at InsightCentral.net were promoting the WOT technique, and apparently some had used it for years, at least until 2005.
The description can be found here under the title "Use Full-Throttle Acceleration":
http://www.insightcentral.net/KB/faq...l#acceleration
Basically, it's going wide open throttle to accelerate quickly up to cruising speed then feathering back. The procedure was used both coming off a stop- ICE off or ICE on and flooring it.
I tried the technique maybe 2-3 times many years ago in my HCH1 but quit because (1) it seemed like a lot of uneccessary stress was placed on the entire drive train and (2) it proved terrible for efficiency. I had found that a slow but deliberate, moderate acceleration was proven to be most efficient in my own vehicle.
I was never sold on the theory that WOT in an automobile would overcome any pumping loss effects. I'd be curious to know how their cars held up (Or not held up)

Re: my engine has a rod knock
I do a moderate acceleration in all my cars and feather back also or begin a P&G. Many times I'll come out of EV mode to the floor to make a stoplight also. With MG2 Assist, I'm not worried because the manual oil pump begins to get oil to the bearings while MG1 is starting the engine at a rapid spin-up.
Now, when the engine is first started after sitting for awhile, MG2 provides the torque until emissions are handled better by the CAT. The timing is retarded by the PCM during the first start-up in the FEH. Most of the energy is coming right out of that big 330V battery in both Assist and first start-up after sitting. This is why those cabbies drive like hell and get 300,000 miles before their made to retire those vehicles to us normal drivers. They drive the Crown Vics the same way because they can get new parts all they want. At least, that was what the cabbies told me recently while staying in Manhattan. My Son, his girlfriend, and my wife sat in the back while I sat in the front of the cabs and talked to the cabbies about their vehicles.

Re: my engine has a rod knock
I haven't read any of the responses to my original post (I'm at work & don't have time to wade through all the back & forth).
I do IT work for a large auto dealership & was also a flat-rate auto line mechanic in my younger days. One of our service techs used to work for a Ford dealer and told me that these engines letting go like this is not a real common problem but certainly not all that rare either.
He personally saw three cases of FEH's with the exact same problem in his time with Ford.
I found a used engine from one of our sources with 60,000 miles on it for $2200 & installed it myself (I have an engine hoist, hand tools, welders etc. in my home garage) so the thing is running again but I'm not sure if I will keep it or not at this point.

Re: my engine has a rod knock
Glad to hear you got it sorted John, you were a regular contributor when I was all new to my '07. Seems like a rare occurrence, ie, the Friday build, or whatever. Anyhoots, seems like you have enough invested to just drive it, make sure it's all good and then sell it. What is the legal disclosure on a vehicle with a swap-in motor? I assume since it's private owner sale, then it's "as-is" with no further ramifications on you part.
I used to do this with my race car built motors and it was assumed that it might blow up in 30 minutes or 30 days. that was assumed by the buyer.
oh. btw. which bearing failed?
