2.3L Timing Chain Replacement Problem

Hi, All. Happy to have found this site and hope to be able to offer some of my own insights in the future. First, I have a question to pose. Currently working on a friendís 2006 Mazda 3 hatchback auto with 2.3L inline 4. It recently developed top end noise indicating timing chain and/or VVT issues. To avoid hassle of pulling engine, decided to do repair with it in the car. Things went well until the point of setting TDC. After removing blocking plug in preparation of inserting crankshaft timing pin, found insufficient clearance between the engine and the PS halfshaft to do so. This was at end of long day, so decided to give it another go later. My hope is that I can find means of getting pin in w/o removing halfshaft. In the meantime, thought Iíd pose the problem here to see if anyone else has encountered this and, if so, was able to find a work around. Thanks in advance for any help.

You might have to loosen or disconnect a motor mount and jack the engine up and out of the way of the interference. If - you don't want to completely remove the engine.
