May has certainly been an interesting and varied month in the JH Service department!
A few images below to show some of the more intersting (and sometimes very dirty!) jobs.
•Land Rover discovery 3.0 for a snapped crankshaft.
•Volvo XC90 Cambelt service
•Volvo 240 Waterpump
•Volvo XC40, came in with hesitation and engine warning lights, diagnosed with Vida to a faulty EGR Valve.
•Volvo XC60, came to us with transmission faults, poor gear changes, slipping gears etc. Diagnosed with Vida and followed the Volvo technical bulletins and found failed input shaft seals.
Stripped and replaced the seals, updated the software to the latest level and recalibrated the gearbox.
•Volvo V90 Classic recovered to us. The engine and gearbox had been replaced over 12 months ago and it’s not run properly since!
After going to two specialists, a transmission specialist, and then an auto electrician, it finally made its way to us.
After a few hours diagnosis into poor crankshaft signals we decided to pull the gearbox off. We found the crankshaft flex plate was 0.45mm out of tolerance and was causing a poor crank signal. (Likely to have been damaged when the gearbox was refitted)
A replacement flex plate was sourced and fitted and now starts and runs like a dream!
•Ferrari Portofino, the customer complained of the windows steaming up and the carpets damp.
After hours of stripping and water testing it was found the water ingress was due to some missing seam sealer on the inner body panels.
• A high mileage XC90 with poor running and an engine that sounded like a tugboat!
After a top end strip it was found that most of exhaust camshaft rockers were worn and the hydraulic tappets had collapsed causing very poor exhaust valve opening.
And Finally…..
This month has seen an unusual amount of rodent damage on several customer vehicles, chewed wires have been causing issues with engine systems, lighting faults, injector faults etc.
