Rockgt302 Posted January 26, 2013 Report Share Posted January 26, 2013 After nailing the car before to move away from an impending collision, the car hit the rev limiter. Now I have a constant knock that changes with engine speed. Ford doesn't want me to drive it and will pick it up Monday. Car has 750 miles. Any ideas?

Crash712us Posted January 27, 2013 Report Share Posted January 27, 2013 Not a clue. Follow your deals instruction, don't drive until you have it looked at. Quote Link to comment Share on other sites More sharing options...
Paulford8 Posted January 27, 2013 Report Share Posted January 27, 2013 I have hit re rev limiter many times. Difference here is you probably didnt have enough engine break in yet. Hope they check it out and get it taken care of for you! Quote Link to comment Share on other sites More sharing options...

TractorAK Posted January 29, 2013 Report Share Posted January 29, 2013 I think what he means is that your car might have had a weak engine for the get go. Unfortunately someone has to get the rare bad one. I have drove my car hard from 28 miles and it runs like a top. I know have 8600 with no problems.

gpfarrell Posted January 29, 2013 Report Share Posted January 29, 2013 Exactly. I think it's hard for a user to cause internal damage to a new engine with an automatic transmission. If the engine has been neglected for years, then banging it off the rev-limiter might be the last straw. Or, if we had 6-speed manuals and say an inadvertant downshift from 5th to 2nd at 100mph, instead of 5th to 4th, then I think it could be the driver's fault. In your case, I'm afraid a defect snuck through and you found it. Imagine the use these engines will get in Police Interceptors and your quick fling with the rev limitter looks like a peck on the cheek! This should be an easy warranty claim.

Well it was the use as the interceptor that made me get one. So the dealer said the engine is done. The #6 cylinder is blown. They are waiting for ford to tell them what to do. Why is there even a wait and see approach, it has 712 miles and I have had the car for about 10 days. I don't want them to repair it, I want a new engine, they said there was metal in the oil. That leads me to think there is now metal in the rest of the motor and the turbos. Quote Link to comment Share on other sites More sharing options...
Crash712us Posted January 30, 2013 Report Share Posted January 30, 2013 I have feeling you will get your wish, I assume ford will want that engine back to see what went wrong. Unfortunately everything has red tape to deal with. Quote Link to comment Share on other sites More sharing options...
goblues38 Posted January 30, 2013 Report Share Posted January 30, 2013 Can you elaborate on how exactly you bounced off the rev limiter? No matter what i do the auto tranny shifts for me. unless you had it in neutral for some reason, not sure how you did what you did. Quote Link to comment Share on other sites More sharing options...

That part gets me as well, at first I thought it may have been the change in tire size but the shift is RPM dependent not MPH. Quote Link to comment Share on other sites More sharing options...
Rockgt302 Posted January 31, 2013 Author Report Share Posted January 31, 2013 Well they are replacing the long block, no answer on the turbos yet. Quote Link to comment Share on other sites More sharing options...
Crash712us Posted January 31, 2013 Report Share Posted January 31, 2013 I would sweat the turbos being hurt by some metal particles in oil. Most will drain away when the engine is tore down. But a 500 mile oil change once back couldn't hurt. Quote Link to comment Share on other sites More sharing options...
Rockgt302 Posted February 1, 2013 Author Report Share Posted February 1, 2013 The engine was ordered I hope it doesn't take to long. This Chevy Malibu they gave me sucks. I guess it beats the corolla they tried to give me. Quote Link to comment Share on other sites More sharing options...
Blaine109 Posted February 7, 2013 Report Share Posted February 7, 2013 If it was my car and I only had 750 miles on it and they are already replacing the engine I would have made them give me a new car... Quote Link to comment Share on other sites More sharing options...

I've been arguing with ford about that, they don't seem willing to give me a new car, yet. Quote Link to comment Share on other sites More sharing options...
gpfarrell Posted February 8, 2013 Report Share Posted February 8, 2013 I think if you're a jerk to them right away, they'll play hardball and you'll never be happy. If you stay cooperative, but also outline reasonable expectations and make sure the dealer meets them, you'll earn their respect and if the new engine doesn't work out then perhaps a new car will. Good luck! Quote Link to comment Share on other sites More sharing options...
Crash712us Posted February 8, 2013 Report Share Posted February 8, 2013 Very true GP, the dealer has no legal obligation to do anything for you. And can send you packing. No that said, do either of these isn't good for business. Your situation is very unfortunate and I would feel exactly the same way. But things like this do happen to every car made. I know this doesn't change how you feel about it, nor would it do it for me either. Perhaps you could discuss with dealer trading it in on a new car, I know you lose money by doing this, but sometimes piece of mind costs extra some times. Not say I would do this either but it's something I would explore. Good luck Quote Link to comment Share on other sites More sharing options...
Rockgt302 Posted February 8, 2013 Author Report Share Posted February 8, 2013 The dealer has been fine, it's not really up to them at this point. The car doesn't qualify for the lemon law yet. It's been 15 days in the shop so far. By the time I get it back it will be 21-25 days. 30 days in 1 year qualifies it as a lemon. If it all comes out fine in the end that will be good. However, I do want some kind of restitution, like maybe cover the first months payment, a free maintance plan, something. I'm worried about putting a tune in the car when I get it back. And who said I'm being a jerk? I've been very cooperative but I am certainly not going to kiss their asses either. And yes they are legally obligated to fix the car and New York has a pretty good lemon law policy and vehicle owners rights system. Quote Link to comment Share on other sites More sharing options...
mjhpadi Posted February 8, 2013 Report Share Posted February 8, 2013 I tried to get a car replaced under the Lemon Law once, and it was more of a hassle then it was worth, plus they get to deduct mileage and any other defect they might find on the car. However, in your case since you have less then 800 miles on the car, it might be worth the attempt. However, maybe the new engine will be wonderful and you will be problem free. Good luck. BTW, a couple of others here have worked with Ford when they got lemons and ended up getting new cars without the hassle of the Lemon Law. Anyway, you go, I hope everything works out for you without a lot of headaches. Quote Link to comment Share on other sites More sharing options...
Rockgt302 Posted February 11, 2013 Author Report Share Posted February 11, 2013 Should be getting the car back Wednesday, they are replacing the torque converter as well. They say its been stuck in a locked up mode. They think that may have caused the over rev. What do you guys think? Quote Link to comment Share on other sites More sharing options...
Crash712us Posted February 11, 2013 Report Share Posted February 11, 2013 I'm no expert, but I doubt it. If the converter is locked up, the car would stall when coming to a stop. Inside a lock up converter there is a series of clutch disc's. these function just like the clutch on a manual trans. And make automatic transmission more efficient. Where in the past old cars the converter would slip all the time. No if it couldn't lock up I could see a possibility of over reving Quote Link to comment Share on other sites More sharing options...

Lock up converts can and do get stuck in lockup mode (usually the fault of the TCC solenoid), but.... because of internal valve body programming, etc. a fail safe device prevents the converter from being able to remain locked when dropping down into first gear, to prevent such stalling. With that said however, there have been very very rare occassions that some bit of dirt/debris has found its way into a passage that kills the above mentioned fail safe procedure. But, very rare! As for the locked converter causeing an over rev....Hmmm very remotely possible, depending on what was happening with pressures and fluid passages in the tranny at the time. It may have been temporarilly prevented from up shifting causing such an over rev. When the converter locks a lot more fluid and pressure is dedicated to maintaining a good TCC lock. Not a series of clutches, but rather just one. The only multi disc converters out there are dedicated for racing purposes. Quote Link to comment Share on other sites More sharing options...
brucelinc Posted February 11, 2013 Report Share Posted February 11, 2013 Regardless of possible lock-up torque converter issues, I don't know why the rev limiter didn't prevent catastrophic failure - unless there was an engine problem to begin with. As others have noted, I think you found an engine problem that was going to occur at some point. On several occasions, when using the paddles, I have had the rev limiter kick in and no harm was done. I no longer use the paddles for maximum acceleration because I don't like the feel of the engine falling on its face when the rev limiter kicks in. Besides, with the tune, automatic shifts are spot-on, anyway. Quote Link to comment Share on other sites More sharing options...
