Good evening, I have the vehicle listed above and unfortunately the oil cooler failed causing the engine to run out of oil. I ordered a used engine but what was sent was an engine from a 2008 Toyota Camry. The company informed me that all I had to do was have my mechanic take the manifold and the oil pan off of my original engine and put it on the Camry engine and everything would be fine. My mechanic was not willing to do the work and now I’m stuck with a used Camry engine and my 2010 Highlander with the original engine still in it. Please help! Any assistance would highly be appreciated!

Hi Wilson,

I am not familiar with swapping these two engines but they are similar so I wouldn't doubt they are correct. However, I agree with your mechanic that this type of stuff just opens a can of worms. If it were me, I would try to return the engine and start over with a direct replacement even if you have to pay a little more. The only reason is, you could end up spending just as much or more trying to make this engine work. You could have someone do as they said and it works just fine but this is a risk and how do you put a value on this risk?

In my opinion it is not work the gamble. However, if you cannot return the engine then you have two options in my opinion. First, tell the mechanic that said he did not want to take it on that all you want him to do is swap the parts as instructed and install it. I assume he is concerned that this issue will become his if he does what they suggest and it still has issues.

The other option is to call around and find another mechanic that is willing to take this on.

Let me know what you find.

Hello,

The engines are identical. The intake manifold probably needs to be swapped because of the intake runner length. The intake runner length will have a major impact on the characteristics of the engine. Longer, flatter intake manifold runners will produce more horsepower(like are on the Camry), while shorter and taller intake manifold runners will produce more torque(like are on the Highlander). The oil pan probably needs to be swapped because of the configuration in the engine compartment, simply to make it fit with the cross-member. Your mechanic probably doesn't want to do the work because he didn't purchase the engine and can't guarantee the engine. I would suggest finding a mechanic who is aware of your situation and is willing to do the work. We can send you instructions on how to replace the intake manifold and oil pan yourself, if you would like. In the diagrams down below I have sent you the engine specifics for both the engines so you can compare them side by side(Note the engine number on the top of the I.D. Pages). Please get back to us with how things are progressing.

Thanks,
Alex
