No mate, no need to jack it up, i just used a jubilee driver. Has a bendy shaft so you can tighten the jubillee clips on bends and get some much needed torque to tighten it up. Others have used a ratchet with a 7mm (i think) and plenty of extenstion bars. As youv probably read, taking the air filter housing off, have all clips at hand and check your turbo for side to side movement. Running your finger in the turbo housing, you may find some oil, just run a bit on the inside of the turbo end of the TIP, easier application. Just stick with it and watch that MAF.
