Hi I have just got a f150 v6 4.2 1997 and it's all running ok but on the top of the rocker cover there is a sticker it's a old one and it's got a barcode on it and a date 15/7/2002 what's this mean is it a new engine from ford

 

most likely. If i was a betting man your truck was a hydrolock victim, and got a used motor, or new motor crate.

 

Thanks how can I tell if it's a new engine it's got the same thing on a plate on the side of the engine it reads
F6TZ-6006-krm
4.2l fr engine
Date mfg 5/17/02. S0016000

 

 

 

 

It's probably a used engine from the boneyard.

 

This is the truck
