Ok Ford guys... Need some help if you can be of assistance. 1) Does anyone know where the Anti-Theft module is on a '02 Ford Windstar? 2) Does anyone know of any common problems with a '00 Ford Ranger with the 4.0 Litre engine? We have no compression in Cylinder #2 and we are thinking it's a valve-spring or rocker that is the cause. Anything common with these engines? Has 100K KM (60K Miles) and has been well maintained... Thanks in advance for all your help. Steve

The compression issue sounds like a stuck valve and have no clue about the Anti-Theft module.
+1 no compression has to be an open or broken valve that is not seating or a hole in the piston.

Not a hole in the piston. We filled the cylinder with air and it doesn't come out the dipstick tube, only the Throttle body. So it's definitely something with the intake valve. Either the valve, spring or rocker... It's on the left head which is a PITA to remove because you have to take so much off the engine. If there was a common problem with these engines that is "known" and would make it not worth repairing, we could just pull the entire engine and put in a used one, but this one has so little mileage we wanted to salvage this one if it was something simple. We are going to pull the rocker cover before pulling the engine to see if it's something simple, but wanted to know if these engine have any common issues. Thanks for the responses thus far.

its usually something in the head on the 4.0 OHV. we usually just replace both heads as that is cheaper than what a machine shop would cost to work them over.

As you know the Ford dealer will tell about AT Mod. As far as this being a common problem on the compression thing, that would no. Ford engines are very durable as a rule.

I don't doubt they are durable, especially the 4.0 because it was used with great success in the Aerostar IMO. I just wanted to know if an engine has problems if there is more common stuff to look for. I think we are dealing with a head problem, so I will be yanking the valve cover to have a look before yanking the engine. *FINGERS CROSSED* it is something simple.

Ford engines have been very durable for for me. Much more so than the Asian engines my family members were deceived into buying before they came back to the fold.
