The team have been going through a series of tests and checks to make sure that everything is working exactly should on the 11,000 mile 1980’s twin turbo coupe.
‘Fit new boost pressure transducer and test and have car running, find fuel gauge not working so partially remove fuel tank, remove fuel filler neck remove wiring and clean up terminals, tape up opnigns on tank, test to see if fuel gauge is working when wires are shorted out and find it does so decided to remove fuel sender unit, clean off paint on top of fuel sender bolts, remove fuel sender unit, test resistance on the bench, find there is none through it, strip plastic covers of sender unit and clean up fuel sender and clean off corrosion and contact points, re-test for resistance, find resistance is still inconsistent throughout sweep, take a look at the fuel vapor vacuum pump that isn’t working, test relay with John to see if it working, Sand blast and paint bracket for vacuum pump, clean up all vacuum pump parts, solder back on blocked wires onto vacuum switch, go through and test wiring and components of vacuum pump, blow pump through with airling to free off motor, Prize open vacuum pump to have a look at internals as it isn’t working remove motor and clean off all carbonisation, then test with a battery, find motor to not be working so a new mupm was orderd, temporarily re-strap fuel tank in, fit new radio cover, fit new battery to car, running up to temperature, find bottom rad hose isn’t getting hot, clean up car and tidy up bench and workshop end of day.’
‘Move car outside and run up with radiator cap off to get to 70 degrees and let the car bubble air out and then cool down do this several times, to try work out why car is bubbling over, do a test to see if compression gasses are getting into the exhaust system, find that radiator cap in not pressurising causing the car to bubble over, remove drivers wing mirror to see why it won’t adjust and find missing adjustment rod. Remove battery to gain access to boost vacuum pump, remove bolts from under wing and remove boost vacuum pump from car, clean boost vacuum pump up and clean up bolts on wire wheel. Finish cleaning up parts for boost vacuum pump and set up for bench test on vacuum pump.
