Ford Trucks with CSK?

The other day I was out at a customer site getting some equipment off of my Freightliner when I heard a Ford engine start and then what sounded like knocking from the engine for about 5 seconds. I turned and saw a 2000 or 2001 F-150 With the "Tritan V-8" badging which means it's either the 4.6L or the 5.4L. Has anyone ever heard of the Ford engines having cold start knock? I have the 4.6L V-8 in my 1995 Crown Vic Police Interceptor, grant it its not the same as whats in the trucks but there are alot of simularities, and I've never noticed any type of Engine noise other then the typical noisy pully and Alternators going bad.

I pulled up next to a Ford the other day at a red light that had a loud knock at idle. I personally have never heard any CSK in a GM.

Being a former Ford Truck guy I used to hang around a lot at F150online in the discussion groups. While I don't remember a lot of discussion about cold start knock there was a lot of discussion about piston slap (specifically those manufactured at a particular plant, but I can't remember which one.) All you have to do is search around over there and you'll find plenty of references to piston slap. Ford has, just like GM, insisted there is nothing wrong, it's a normal condition, etc. Anyway, it seems Carguru is right all the manufacturers seem to have some similar problems.

Many Fords do have piston slap and pinging. Pretty much all of our Fords since '78 have had a ping. It wasn't as noticeable in the older Fords, but our 3.0 has a very noticeable pinging common to this engine. We put 87 octane in it and have never used anything higher, so I don't know if that is the reason.

 

We had a Nissan that knocked like nothing else...sounded like a diesel.

If you read Ford forums you see plenty of posts about CSK on Ford pickups, especially 5.4s. Don't see alot about 4.6 engines. Every now and then someone complains about a 6.8L V10 with cold start knock. Seems to be alot more noise issues with GM's newer engines than Ford or Dodge right now. I think some guys blow it out of proportion. A little noise on startup is no big deal as long as it goes away when the engines starts to warm up.

 

So far my V10's been quiet, which is nice because the 5.3L Silverado I had sounded like a diesel for minute or so every time I started it but it did run smooth and quiet once it warmed up. So far as I could tell it never suffered any performance loss and I used it for towing on a regular basis.

 

Wanna talk about a quiet motor-my wife's Chevy Trailblazer's 4.2L inline is without a doubt the quietest motor I have ever owned. When it's idling in park there's no vibrations or noise at all. I think GM has a real winner with this new series of inline engines. I anxious to see how the I5 for the Colorado plays out. :mad:

      ‘25 Silverado purchase- back to dealership for bumper/radio issue

      The no sound problem is the audio amplifier. The audio amp has a heatsoak issue in some circuitry which causes it to miss the wakeup handhake. If it doesn't respond within a certain time parameter, then you get no sound. I brought it in and had the software update, but after further testing the tech made the call for a new audio amplifer. The software update I belive gives more time for the amp to respond, but if the amp is defective then you can still get no audio at times. After the update it went 12 days before no sound. After doing some research, apparently the fix is a new (updated) audio amplifer, the circuitry internally has been improved to better deal with heat. I had to wait 2 1/2 weeks because at the time, it was on backorder with no eta. Well the amp came in earlier this week. I had the amp and programming work done today. After picking it up I stopped at a few places, and whenever I started my truck, the audio was on instantly, so whatever they did it appears to work because it's never had sound that quickly......Hope this helps

      Make sure the latch mechanism is properly greased. Look at the catch for fresh marks/scratches. And see if it has moved a little, too.

      Thoughts on these wheels?

      By PBNB · Posted

      I have the 18" black mutilspoke wheels that came with my truck. I like them as they are very subdued and look good with the 295/70's    I am sure that the next set of wheels I get will be some after market all black wheels. Or maybe some AT4X wheels.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Interesting question which you partly answered in the word 'potentially'. I think that is going to be a 'point of reference' inquiry. What are the touchstones?    This will sound petty but it is the main source of end fighting in threads on this topic. Define a motors "Life". Think about the various arguments that have been entertained on these pages in that very argument.    I can only speak from my viewpoint. Engine "Life" in my world is defined by power cylinder integrity. For the majority of engines it is the bore/ring interface that quits first. Loss of seal. Oil consumption and loss of power. Most Pro motor builders would agree and there is a good deal of information on using "Leak Down" as a primary indicator of bore integrity. At home a compression test is more the thing. If we can agree on that then I think CC Jensen has done its homework and I'd find it valid.    Now by my own definition, Dizzy, wife's Ecotec 2.4 I-4 has been dead since about 80K miles. And yet we have logged over 200K miles more on it. "Life" and "Usefulness" are therefore independent.      I know a mature fella right now who has just hit 300K on a Mitsubishi 3A92 NA MPFI motor and has done compression test every 100K. It was 205 psi after break in and is now about 195 and still even. He uses shelf oil but good filters and adheres to a 3K mile OCI. He even do UOA's on each of them for the first 50K.      I also know a fleet mechanic with that same motor that gets 300 to 500 K out of them but the are oil using, wristpin sloppy, skirt slapping motors. He ran one with a piston pin so loose the piston was bouncing off the cylinder head for about 20K miles before he called TOD. Both of them claim success.
