This is the engine most associated with "348" branding (3.4 liters of displacement effectively).

A: Most manufacturers recommend every 60,000 miles (96,000 km) or 5 years, whichever comes first. For high-performance variants, this interval may be shorter. Autodata 348 includes the service interval in its data sheet. autodata 348 top

Autodata 3.48 is a version of the famous technical information system used by professional mechanics, garages, and MOT test centers. It was designed to provide critical data for vehicle servicing, repairs, and diagnostics without the need for an internet connection. This is the engine most associated with "348" branding (3

This version is widely considered one of the last great "standalone" iterations of the software. It covers the vast majority of vehicle models produced up to roughly 2008. For many workshops that specialize in older vehicles—specifically those from the late 80s, 90s, and early 2000s—this version remains a surprisingly relevant tool.

Beyond the “top” procedure, Autodata 348 provides critical torque values. Loose or over-torqued fasteners will undo your careful timing work. Below are typical values for engines covered by this reference number (always verify by software):

| Component | Torque (Nm) | Torque (ft-lbs) | | :--- | :--- | :--- | | Crankshaft center bolt | 150 Nm + 60 degrees (angle tighten) | 110 ft-lbs + angle | | Camshaft sprocket bolts | 65 Nm | 48 ft-lbs | | Timing belt tensioner bolt | 25 Nm | 18 ft-lbs | | Timing cover bolts | 10 Nm | 7 ft-lbs |

Angle tightening requires a torque angle gauge or a highly experienced hand.
