Can I put the B5254T motor into my XC90 that originally came with a B5254T2?

A mid-size luxury crossover SUV, the Volvo XC90 made its debut in 2002 at the Detroit Motor Show. Recognized for its safety, practicality, and comfort, the XC90 is a popular vehicle around the world. The XC90 proved to be very popular, and very good for Volvo's sales numbers, since its introduction in model year 2003 (North America).

Ya but as I was saying, I did that with my impact gun. They both turned about that much when I loosened the bolt

If you got all five lined up, I would be pulling the Cam cover off to see if something is going on in the Valve train.

Watch it on the Cam cover to make sure you don't warp it. The Cam Cover and the head are line bored at the factory. You cannot just run out and by another. The tool kit above has tools for removing and installing the Cam cover.

It would be best to back up as you are bringing up things randomly.

So right now the motor is out of the car. The motor does not turn over freely. It turned over freely before you did some work on it.

So what work did you do on the engine?

Is the exhaust and intake manifold on the engine? If they are not installed, you can look at each valve to see if you have a valve issue. If they are installed they are easy to remove with the engine out. As the engine will not completely rotate a leak down test is not an option at this point.

It is possible to set the crank to its timing mark, remove the timing belt and let the valves close. You can see this visually and do a leak down test from here. But that would be later.

One other item - on Volvo engines the timing slots on the back can easily be set 180 degrees off if one is not careful. You need to pull up pictures and make sure you have them aligned correctly. Don't recall which one, but one is offset of center - this could be your issue.

At this point, reading between the lines, it appears you have a bent valve, a cam that is 180 degrees off, a foreign object causing issues or something else you did wrong. Need to work through it from the beginning, the more details the better.

Report back.
