Buying Tips for 1987 Daimler Sovereign
- Inspect the 4.2-litre engine block between the middle cylinder bores for hairline cracks and deck sinking, which cause repeat head gasket failures.
- Check operation of the twin fuel tanks and dashboard selector switch, confirming that fuel feeds and returns correctly without cross-filling or overflowing.
- Examine the rear suspension subframe and inboard disc brakes; leaking differential output shaft seals soak the inboard brake pads in hypoid gear oil.
- Scrutinise the front subframe vee-mountings and rear suspension radius arm bushes; perished rubber degrades the celebrated magic-carpet ride and causes tramlining.
