Cribblog 2019     [Post 3]

   25 April 2019.

This cribblog post also includes sj's 2019 visit, not a lot of activity to report on from that although we were able to catch up on what we had been doing here in Banbury with our new house and environs and also in the US with her school projects and the amazing puzzle hunt she is devising and running for nearly 200 people in the summer. I am bound to secrecy on the latter but expect a proper report later in the year when all can be revealed.

A trip to Cribbit was of course essential and sj was able to supervise the re-fitting of the injectors and spend a night on board enveloped in heady diesel fumes.
After she left we have been able to get the engine running again. A long catalogue of faults which I think have been ironed out now and can be read in all their gory detail below the pics.

Could they be Cadbury flakes?

Could they be Jaffa Cakes?

Could they be chocolate digestive biscuits?

Back on my mooring, canabalised the old injector pump for its bleed valve.

Finally drilled the hole in the hull for the shower pump drain ... now just need to clear the junk out of the shower.

As soon as Cribbit was re-launched, I started up the engine intending to run the big inverter so that I could make new stern berths with the power saw. Well the engine ran for all of four minutes and then cut out in a most determined manner. I recognised the symptom as being fuel starvation, a problem I had experienced [and fixed] previously, though always promising myself that I would one day do away with the motley collection of shaky old fuel pipes and their multiple joins. Clearly that day had arrived. She also needed to be inspected for a Boat Safety Certificate and one of the items required for this was a new engine spill rail. So a good opportunity to replace the lot, fuel and return lines and the spill rail.

Headed over to Calcutt Boats for the spill rail, they have lots of BMC spares. Then to Pirtek for the fuel lines. Really struggled to fit the spill rail as it appeared to be too thick for the banjo bolts to grip in the injector tops and there was one that just would not locate. Advised to go to Thames Valley Electrical and Diesel in Reading and took the offending injector with me. They sorted me out with a new top and a single banjo bolt, the only one they had in stock. At the same time I asked about replacement electric fuel lift pumps and decided that I would buy one as was somewhat fed up with standing on my head in the bilges with a sore finger from pumping the engine one by hand.

TVED also said that they could re-condition my injectors for me and although I had had this done shortly before Cribbit sank I decided that this wasn't such a bad idea. Especially with the dodgy tops and worn banjo bolts, so removed all the injectors and ordered a set of new banjo bolts and copper washers.

When I got the new spill rail from Calcutt, I had been a bit surprised by the long tail at its end and then discovered an unused spacer on the engine that had never been used during my time on board [26 years and at least three new spill rails] but was just the correct distance away. So back to Pertek with the new pump to get pipes fitted to it directly and a new length from the fuel filter to the new position of the spill rail entry. This all pleased me as I was never happy with the end of the spill rail flapping in the breeze and I loathe connections in pipes when they can be fixed directly. Pirtek also braised up the hole in the spill rail terminator and braised a new end for the fuel line entry to the high pressure pump.

By now sj had arrived for her Easter break so she and I went back to TVED to collect the injectors, bolts and washers. [TVED tested the injectors and pronounced them to be OK and re-threaded one of the damaged tops.]

Re-fitted the injectors and spill rail [easy now with the new bolts and re-furbished tops]. Switched on the pump, removed the bleed screw from the injector pump and ...mostly air and spitting fuel ... no way was that going to work. So what next? Well very suspicious of the fuel filter as its bleed screw was only sealed with a dodgy looking nylon washer, decided to put in a new filter and beg assistance from the yard. They fitted the new filter and declared the O rings to be fitted properly so tried again ... even more air this time ... Well it can only be the main feed from the tank, took off the connector and its end seemed to be loose ... and then fell off ... rather a convincing fault. Me overjoyed to find something tangibly wrong at last.

So over to MEC Marine at Wargrave on the Thames [who had supplied the original Vetus tank and fuel gear]. They had not got a pipe in stock but robbed one out of another tank kit so were able to supply me straight off.

Only snag was that this one was too long and had a crimp bulge for connection to a flexible hose. No matter, both could be sorted with the hacksaw. Pleased to see that it was stainless steel too as the original had been plated mild steel and had started to rust [in a fuel tank!]. While the hacksaw was out decided to shorten the bleed plug in the fuel filter as well so the dubious washers wasn't needed.

Put it all back together, switched on the pump, fuel and not air came out of the injector pump bleed, loosened the injector feeds to bleed them as she cranked and then when all was tight, off she roared with a bit of black smoke for good measure.

Very pleased with this of course so decided that I would go and fill the water tank the lack of which had been very annoying. Got about 15 metres from my mooring when ... the engine stopped ... dead. Managed to pull her back to her berth after a bit of a struggle as we were in the middle of winding and she was at right angles to the cut.

Tied her up again and set to contemplating the engine. Well there was quite a bit of diesel under the injector pump and the fuel pump was running continuously but where was it coming from? First suspicion was the bleed screw on the injector pump, but that looked OK but only because so much fuel was leaking that it looked clear. Clearly the bleed screw needed replacing, the last one had been dropped overboard by the people I had in to fix the engine the last time it had failed miles from anywhere.

Dave thought that they might have an old injector pump with one on that we could rob in their leaky last ditch stores so we had a look to no avail so I was resolved on another trip to TVED when he appeared with a grubby unit he had found under a bench, the official bleed valve was missing but there was another on the other side that was still there and now it is on mine.

Started her up again and this time did actually get her down to the water point a 100 metres away and back. Slow running was a bit fast but have slowed that down now and she is still a bit unsteady but I think she will run better once she has had a bit of a run, planned for the weekend.

Lots of help from local and more distant suppliers:
