While in the summer of the 2019 a few of our Bavaria 39 Tessa Jane began producing black fatigue smoke and suffering a decrease in power from her JULY 2004 Volvo Penta MD2030. Initial investigations covered the typical suspects for instance fuel issues, blocked exhaust elbow and the like, which resulted in the fitting of the shiny new stainless-steel harrow elbow.
But I got unable to isolate the exact trigger before our annual cruise regarding the Channel Islands and north France, so we merely kept the revs compact while motoring and preferred our holiday.
However, if motor-sailing from St Peter Vent to Cherbourg, the smell of unburnt diesel increased and a few miles from the west entrance into the harbour we started giving out rather some white smoking.
We limped into Chantereyne marina and were luckily willing to berth on the hammerhead, which reduced how many time manoeuvring under vitality and kept the white smoke suitable minimum. We obviously was instructed to address this tout-suite thus cancelled our plans to remain onto St-Vaast-la-Hougue and go about investigating a possible faulty or blocked injector.
Astonish breakage
I successfully drawn entry two injectors (of of which three), but the aft-most just one single was surprisingly loose. Diesel injectors has to be fitted with relatively substantial torque, so when I organized to removing the retaining nut to your fuel leak-off pipe attached with the rear cylinder, I became genuinely surprised to see the complete injector rotate as fine. Inevitably, the result of your rotation was that your own brass leak-off pipe pennyless.
With the three injectors most pulled, a quick inspection health in their ports highlighted that in which rear injector port were being completely blocked with carbon build-up, and I attributed the chief cause to the loose injector. We also noted that there looks like it's a lump of a thing that appeared as in the event calcified carbon still in part blocking the injector port, but this proved out of the question to eliminate.
I cleaned out the backed injector convey, and made a temporary repair for any fuel pipe using JB Weld in advance of reassembling the system. A good engine test confirmed many of us had, at least, ceased the billowing white smoke cigars.
Due to a deficit of brazing equipment in mother board, which might have been utilized to affect an even more permanent repair on the leak-off pipe, I decided to visit some local garages and workshops to know if anyone could fashion a repair with luck. However, I was out connected with luck.
Plan B therefore was to promote the Volvo Penta Motion Service (VPAS) to resource an upgraded part. This is now Friday afternoon prior to August bank holiday and also we had crew joining us across the following Tuesday ready for a sail back across this particular Channel. VPAS were beneficial with identifying the specific part number, locating a new local dealer, dealing utilizing translation challenges, and getting them to produce it right to the marina towards the Monday. However, I ended up funding 200 Euros for a part you will definitely get online in the UNITED KINGDOM for £50.
With the replacement vigor pickup installed and wine beverage beverage stocks replenished all of us appreciated a lovely sail back throughout the channel stopping overnight indoors Yarmouth, before continuing on to Portsmouth. Engine power has become still slightly reduced, but there were no billowing white smoke cigarettes.
I knew I’d ought to remove the cylinder head to be able to identify the foreign object in the rear cylinder injector interface, and as the boat can be moving to her winter time home in October, we enjoyed a number weekends in the Solent devoid of incident.
