Does anyone know what the differences in a 2.3L engine in a 2007 Ford Escape Hybrid versus one in a non-Hybrid are? I understand that there is a difference in the timing. I'm not sure if the cams are completely different or just the gears. I would also like to know if there are any other differences. Basically, I want to know what I have to do to a 2.3L non-Hybrid engine so it can be used in a Hybrid?

 

Why are you looking at using a non-hybrid motor to be used in a hybrid vehicle?

 

They are much less expensive and more available.

 

Different camshafts, compression ratios (pistons), starting systems etc. The block maybe the same.

Crank, rods, pistons, camshafts are a given. The ECU, fuel injectors, starter (hybrid doesn't have a conventional one) and cylinder head are the other likely possible differences as well.

 

The e-CVT is also a big difference between a hybrid and non-hybrid. You'd probably have to ditch that transmission if you wanted to de-hybrid a FEH.

There have have been people on this site who claimed to have rebuilt the engines of FEHs (even with junkyard hybrid motors). But these days I bet not that many people are going to want to sink that kind of money in to a 8+ year old Escape.

 

I'm not trying to de-hybrid my FEH. I need to either replace the motor or rebuild the one I have. I have been told that it is less expensive to get a used engine. I have not had any luck finding a replacement. If the differences were minimal, I would have bought a used used non-hybrid motor, used the good parts off my old motor and bought anything else that I needed.

 

Just curious about your original engine. How many miles are on it and how did it fail?

 

Just under 142000 miles. Spun a bearing and intake cam has one worn lobe. Oil level was perfect 1-1/2 weeks before the bearing spun. After it happened I checked the level and it was down 3-1/2 quarts. Signs of oil where the engine bolts up to the transmission.

 

So you're saying there's a chance?
