A delivery van accumulates engine life on a clock its odometer never shows: hours. Idle time at each drop, low-speed work between stops, cold starts at the depot — the 670’s chains, injectors and filter all age against that hidden clock. Two NV400s with the same mileage can be a world apart, which is why the assessment reads duty alongside condition. The registration lookup confirms the code; the tests read the life the van has actually lived.
The 670’s timing chain announces wear the family way: a rattle in the first seconds of a cold start, lengthening as the guides and tensioner give up. On a van worked in hours rather than miles, that rattle tends to arrive earlier than the owner expects — and it matters more, because a chain failure inside a working NV400 costs the engine and the week’s rounds together. The stretch check converts the noise into a measurement, and the measurement makes the repair-versus-replace comparison honest.

Hard-worked 2.3s churn through injector seals, and the symptom has a signature: a tick that tracks with load, carbon rings around the wells, rough running and poor hot starts. Caught early, a reseal is the cheap answer. Worked on, the seats erode, and the honest conversation becomes replacement — with machined seats, which is what the reconditioned route renews as standard. The spill and balance tests place your van precisely on that line, which is why they run before any price is written.
Town delivery is the regeneration cycle’s worst enemy: the van never reaches the exhaust temperatures a filter needs, so soot loads, the pressure sensor complains, and limp mode arrives on a Tuesday. Any replacement decision on an M9T 670 should read the filter’s state first, because fresh rings behind a saturated DPF simply relocate the fault. The specialists assess the emissions side while the bay is open and quote it in the same visit — one decision, one warranty, no repeat visit.
On a working NV400 the arithmetic includes downtime, not just parts: every reseal buys time but costs a day in the bay, and the seats never get truer. The tests decide where the line sits — strong compression and fresh seals point at a repair; eroded seats, chain wear and a loaded filter point at a reconditioned engine with all three renewed. The quote shows both sums side by side, priced for a van that needs to be earning again by Friday.

Reconditioning is the usual recommendation for working 670s — chains, seats and rings renewed, bench-tested to the van’s calibration. Tested used suits newer or lightly worked vans whose donors test strong. Supply and fit converts either into a single fixed-date booking with recovery included, which is the format an operator needs. The comparison arrives matched to your exact code, with the differences explained in plain terms rather than left in the small print.
Fitting a M9T 670 engine means coding the injectors to the ECU and confirming the timing before handover. The network workshops handle the full changeover, and every installation is warranty-backed.
Reading duty alongside condition is not a flourish \u2013 it changes the advice. An idle-heavy 670 with modest miles often needs injector and filter attention long before its chains demand anything; a motorway-worked van may show the opposite. The assessment therefore reports both stories \u2013 the hours the van lived and the measurements the engine presents \u2013 and the quote is built on the combination. Owners are often surprised which side of the engine\u2019s reputation their van actually lands on.
