Yup, pop the top cover off the steering column, remove the bottom cover, it will have 2 T25 Torx screws and a T15 Torx screw. Now you remove the two T25 screws that hold the turn signal switch to the steering column, and unplug the connector. Reverse process. Now drive 45 miles per hour in the left ...

Rear isn't a lot of fun, but it's only a few bolts. First remove the upper engine mount bolt so you can raise the rear of the engine later. Place the car on jack stands.

I have been informed that Volvo no longer offers the OS1 piston for the B5254T engine. I learned this .020MM OS piston isn't available after having my block bored, which is a pain in the wallet. This is Volvo part number 272242. The OS2 .040MM OS pistons can still be ordered, or so I've been told, u...
