After having its leaking head gasket replaced under warranty, this Delica needed its head bolts re-torqued.

Access to the head bolts on the 4M40 turbo diesel is easier than on many engines because the camshaft is not in the way. Half of the bolts are actually external to the cam cover!

Unfortunately in the Delica the engine sits mostly under the dashboard, which greatly limits access from above - and the intercooler is also mounted on top of the engine.
