All T-Type (TC/TD/TF) problems All workshop issues

Common Engine, XPAG/XPEG (1,250cc/1,466cc Inline-4)

Timing Chain Stretch

Symptoms

A rattling noise from the front of the engine, particularly on startup or at idle. The engine may feel down on power and the timing may wander.

Cause

The single-row timing chain stretches with mileage. The original tensioner is a simple spring-loaded slipper that can only compensate for so much wear. Eventually the chain becomes loose enough to slap against the timing cover or jump a tooth.

Fix

Replace the timing chain and tensioner.

This requires removing the timing cover (front of the engine).

Fit a duplex (double-row) chain conversion if available, it's stronger and lasts longer.

Cost: $200-$400 for parts.

Minor Engine, XPAG/XPEG (1,250cc/1,466cc Inline-4)

Oil Leaks, Everywhere

Oil weeps from every gasket surface, rocker cover, timing cover, sump, rear main seal, and anywhere two castings meet. The area beneath a parked T-Type will have oil spots. Some engines leak enough to require topping up between services.

Critical Engine, XPAG/XPEG (1,250cc/1,466cc Inline-4)

Low Oil Pressure (Worn Bearings)

Oil pressure drops below 40 psi at cruising speed when warm, or below 15 psi at idle. A knocking sound from the bottom end, particularly under load, confirms the diagnosis.

Dynamo (Generator) Failure

The charge warning light stays on above idle, the battery goes flat, and electrical accessories dim. In some cases, the dynamo seizes and the drive belt snaps or glazes.

Overheating

Coolant temperature climbs above normal, particularly in slow traffic or on hot days. Steam from the overflow. In severe cases, the engine boils over.

Minor Wooden Body Frame

Rot in the Ash Frame

Doors don't shut properly or are misaligned. Body panels flex when pushed. Gaps between panels are uneven. The body feels "soft" when jacked up. In severe cases, the body visibly sags or the scuttle area cracks.

Minor Wooden Body Frame

Body Flex

The body creaks and flexes over bumps. Doors pop open over rough roads. Scuttle shake (the windscreen frame vibrates relative to the body) is noticeable.
