I have been reading the "slap" problems discussions and was wondering the date the Windsor plant started adressing the problem with its' "fix"? My engine has a date of 7/7/99 on its sticker -- is this before or after the "fix was started? -- Thanks

 

I believe I read that enginges manufactured after 4/99 were piston slap free.

I could be wrong tho

Hi Markmizzou,
What I have been told, is that any truck with the build date around October of 1999 has the corrected engine that's not suppose to slap. I guess that it's the 2000 Model year trucks and vans. Bugman.

 

BadAngler,

I recently read a post on here that another F150 member has the slap problem and their build date was in May 1999.

2000 F-150 XLT, 4x2, Superchipped 5.4L Supercab, Styleside, Black with silver two-tone, 3.55 rear, class III towing package with heavy duty cooling package, 4 wheel disk ABS, overhead console, sliding rear window, keyless entry, dark graphite interior, in dash CD, factory leather wrapped steering wheel, Pendaliner bedliner, K&N air filter, rubberized undercoating, cabin filtration system, Bugflector II, 5W-30 Mobil 1, engine build 10/4/99

 

My 5.4L was manufactured on 5/10/99. The dealer's service department performed a cold start diagnosis on my truck yesterday morning, and they confirmed that I do in fact have the piston slap problem. The truck had been left outside at the dealership overnight. The temperature was about 45F degrees, and I was there with the service technician when he started the engine. They are estimating about one month to get a new engine. The truck has 8800 miles on it. Too bad!
