I did mine but this was about a yr ago you need a pulley puller for the crank pulley and I bought the special bolt from MMR to get it back on I had some hints from a member on here not a job I would recommend doing if your unsure.......I did it before I put my new motor in and as it turned out one of the links had jumped 1 link and timing was off on the drivers side so I had to basically redo it in the car which is a huge pain
yeah, this is one I would leave to the professionals... if the engine was out, that would be different, but with the engine in the car, it could be a pain...especially the oil pickup tube bolts....I think one is not too bad, but the other is a PITA....
