No significant external modifications except for wheels (see details below) and Hella front fog lights.
Cooling system overhauled
1. radiator boiled/rodded
2. all hoses replaced with silicone hoses (turned out to be counterfeit - more in 2018 below)
3. new thermostat
4. new tires
The rest of the Service C was stalled due to personal issues.
Service C 'Plus'
Replace (all new parts unless otherwise noted)
1. both fuel pumps - Bosch
2. fuel accumulator - x40, not OEM x39 as JAE says x40 supercedes. Have use x01 on 88 Esprit for 50K miles with no problem
3. turbo to air cleaner rubber hose (OEM)
4. both gas tank feeder hoses (tanks are 100% rust free despite reputation for rusting out - 71K miles)
5. Gates blue timing belt
6. valve tappet replacement (cast iron OEM rumored to crack anywhere from 50-70K miles) - JAE new steel parts
7. valve adjustments - new shims as needed (requires removal of cam towers)
8. new sparkplugs
9. new wires
10. new inductive pick up (car developed a miss prior to servicing - suspected bad wire in inductive pick up due to vacuum advance stress)
11. new cap and rotor
12. new fuel filter (OEM)
13. new pre-fuel filter (aftermarket mod to prevent rusty tank particles from damaging new pumps)
14. new alternator strap (aluminum replacing plastic aftermarket that buckled)
15. new catalyst (aborted due to difficulty of finding flanges - may need to go NOS)
16. new SJS aftermarket cambelt sprocket - random reports of cracking on other models; old sprocket was fine
17. had leaking oil line fitting repaired temporarily (used barb to connect new hoses to old 30 year old hoses)
Back from shop - at about 75K miles, the counterfeit silicone hoses - one key hose near the camwheel cut into it, resulting in a huge leak.
1. Got JAE silicone hoses to replace them.
2. Replaced thermostat (only 5K miles, but since it was out, may as well).
3. Replaced 30 year old oil lines with 1 piece hoses.
4. oil cap cracked after 31 years (red plastic) - got OEM replacement from JAE.
