My dad told me today that he's going to be changing the camshafts in his Mustang (2010). Now, from what I understand about engines, which is not too much, you need to remove the heads and a bunch of stuff. However, do we need to remove the entire engine from the car itself? Do we need an engine lift to change camshafts? Because I don't have an engine lift :(

Nope. You should be able to change Cam shafts with the engine installed.

Crankshafts on the other hand require engine removal.

It's a DOHC motor right? Shouldn't have to pull the heads at all.

Heads stay on, no need for an engine hoist. Just need basic hand tools and knowledge.

That's what I was thinking - camshafts top (especially if they're 'overhead') crankshaft bottom end.

How many miles are on the car?

How much of a cam is your dad thinking?

I hope it's mild because I would not mix a really big cam with a motor that's got more than 50k on it without doing a compression test first.

In many cases, the motor will be just fine, but when you pull the valve cover off, what you should really do is grab a wrench, and from the crank pulley, try to turn the crank so you can visually inspect every single existing cam lobe. If any of them show significant signs of wear, or look like they may be damaged or otherwise off to you, take a ton of pictures, and don't proceed until you can verify that nothing is going to be a problem with a different cam.

I'd rather do it the "more complicated way" of keeping the stock cam installed when cranking over the motor simply because in the case of something being a problem, you can pop the valve covers back on, and consult a professional. It's easier on you in the long run.

Lucky you, having an OHC motor. If I wanted to do a cam in the 5.7 HEMI, I'd have to tear the whole damn car apart to get to it.
