But, when all was said and done, Milo was back on the road and all seemed well.

My son has had the car at college so I haven't seen it much recently. But today I noticed all manner of oily mess on the right side of the engine. After poking around a bit, I suspected the source was in and around the chain tensioner. So I cleaned that area thoroughly, both the tensioner itself and the parts of the head and block directly beneath the tensioner.

Started the engine, tensioner is bone dry, but there's fresh oil coming out at the "lip" of the head where it meets the block."

My questions:

1. Can this be anything other than a leak in the new head gasket?

2. If, as the mechanic claimed, he used all new head bolts and followed the FSM tightening procedure to the letter, how does something like this happen?

3. Any advice?
