All XJ6 (Series I-III) problems All workshop issues

Minor Bodywork and Rust

Floor pan corrosion

Symptoms

Floor pans rot from underneath or from above (water sitting under carpets). In severe cases, you can see the road through the floor.

Cause

Water enters through failed windscreen rubbers, door seals, heater matrix leaks, and blocked drainage. Sound deadening material holds moisture against the steel. Carpet and underlay hide the damage until it's severe.

Fix

Cut out the rot, fabricate or buy replacement floor sections, weld in.

All carpet, underlay, and sound deadening must come out for proper inspection and repair.

Budget $3,000-8,000 AUD depending on extent.

Cost mentioned in fix

Budget $3,000-8,000

XK engine oil leaks

Oil weeps from cam covers, timing chain cover, sump gasket, and rear main seal. The engine bay is perpetually oily. Oil drips on the exhaust and creates smoke.

Common Engine

Cooling system inadequacy

Engine runs hot, particularly in traffic or on warm days. Temperature gauge climbs, coolant may boil over, heater blows hot when it shouldn't.
