So my new to me 124 300 24V Diesel was booked in at Ian’s today for some preventative maintenance as it is just about to roll over 200K. The fuel pipes and breathers were up for renewal as they were brittle/non opaque and generally in bad order. Plus a possible diff change, as the gear changes had always been "jerky" since I got the car, around 1000 miles and a couple of months ago. Well talk about a job growing legs. Under the manifold was a defunct/disconnected pre heater system for the fuel. Someone had been running this darn thing on WVO (Holy carp Batman) So that was taken out. The vacuum system was a cobbled together total mare of various non-standard pipes. Many running nowhere some just not connected to anything. Much head scratching and fettling followed with pipes renewed and routed correctly. Once that was sorted the gearbox cooling pipes which run through the radiator were checked. Well I should have said "should run through" the radiator. Some wassert had just looped the pipes together and they went no where near the rad. (All hidden by the undertray) So that was sorted and a gearbox oil change was carried out. The car now runs like a dream. Gear changes are bob on without a diff change (Ian did detect a slight clunk on some changes but new diff mounting bushes have been ordered to sort that) Kickdown really really works. It worked before but it is now "rocketship" compared to what it was. The rear headrests now bob down too when commanded to do so by the dash rocker switch. Big thanks to Ian and his team. Poetry in motion Ian, poetry in motion.
