If anything does need repairs, that engine's parts are dirt cheap. To save heartache, check to see if the mounting bolts are at least grade 8.8. If not, then odds are none of the bolts or studs have been upgraded and still chinesium. Replace head, engine mounting, exhaust, chain tensioner and wheel sprocket bolts with 8.8 or 12.9 bolts (I use 12.9 because it's not much more expensive for quality security). It really sucks being stuck miles from home or your destination, pushing a stack of bricks (my profile pic) just because of a broken bolt.
