Ford Trucks with CSK?

[RyanZ71]

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.

GM is not the only manufacturer with this problem. Just about every manufacturer has had some issues with CSK.

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.
