As you know, I can't help at all, but I feel your pain.
Hope you're back in business cheaply and speedily.

You've not perchance pissed anyone off to the extent they've slipped a gallon of petrol in your tank?

I'm not easily offended, but I do draw the line at any sort of comparison with a fucking idiot who just thinks he knows what he's talking about. Interesting then that you completely misdiagnosed the fault with Ricco's engine whereas I got it completely spot-on. As I recall it, I was told that your worthless advice had been to simply have the head gasket replaced on an engine that didn't have enough compression to fire or run, whereas my verdict was that the engine would have to be lifted out to rectify the problem, and to check/rectify any valve or injection timing faults/errors that might have contributed to or caused the problem in the first place. When first checking the engine over to diagnose the starting problem it was blowing a lot of vapourized and partially burned fuel smoke up the pushrod holes from the crankcase and the valve gear and surroundings were very dirty and sooty, . . . common symptoms of excessive piston and ring blow-by OR, sometimes, a blown head gasket. The owner assured me that there hadn't been any problems with overheating, over pressurizing of the cooling system, or coolant loss, which pointed to broken or stuck piston rings being the likeliest cause. If the problem turned out to be stuck rings, which it was, then checking both valve and injection timing as as a possible cause of the carboned-up rings before it went back into the boat would have been sensible precaution, but as far as I'm aware it wasn't done, thanks mainly to you and the input from the equally stupid fitter from the nearby Vetus agents, who, incidentally had been unable to offer any useful suggestions as to why the engine wouldn't start a few days earlier.

Unless the tank was almost empty, a gallon of petrol wouldn't stop it running, we used to routinely put 15% petrol in the diesel tanks in Russia in the Winter to stop the fuel waxing. If the fuel is contaminated it's more likely to be with water.

Then your recollection is wrong. My opinion was that the engine fault should have been diagnosed with the engine in situ, and it was likely to be an issue with the piston rings (and if piston rings are gummed then they can often be freed without removing the engine), but in any event that is academic since the engine had already been removed and the boatyard subsequently booked to carry out the repairs before I even arrived. I did agree that it was a sensible idea to get the boatyard to carry out the repairs because after three weeks broken down and a CRT overstay notice being issued with no progress whatsoever being made with the repairs Ricco was rather understandably keen to get underway again.

The fault WAS diagnosed with the engine in situ, Mr Shit-for-brains, . . and having established that piston and ring problems were the most likely diagnosis, I told the owner that the engine would have to come out to a) fix the problem, and b) to allow the valve and injection timing to be checked and put right if necessary, . . a task which, thanks to one of the worst and least accessible engine installations I've ever seen, wasn't possible with the engine remaining 'in situ'. You have at least remembered some aspects correctly, though, . . it was you who thought that the best people to fix the engine were the ones who couldn't figure out what was wrong with it in the first place. Have you been sniffing too much of the only item in their fitter's toolbox which they had used in their earlier, abortive attempts to locate the problem and get it going, . . . 'Easystart' ?

Well, Mr Shit-for-brains, at least you've got that bit right, . . you thought that the best people to fix the engine were the ones who couldn't figure out what was wrong with it in the first place. You'll excuse me if I don't join in with the name-calling but I find it rather puerile. As I said, Ricco had already booked his boat in for repairs before I even arrived at King's Lock so short of exercising some type of psychic influence on Ricco from afar then it wasn't a decision which I influenced, although I did agree that it was the right course of action to take. Had he not done so I have no doubt he would still be there now.

Meanwhile........back at andy's problem....... Rog Personally I'd check for contaminated fuel in the first instance by rigging up a temporary gravity fed tank and bleeding through, followed closely by a compression test. If compression is down then the cylinder head will have to be removed to ascertain whether it is a problem with an exhaust valve or the piston rings. If it is the former then it will need new valves, if it is the latter then depending on what the problem is it *might* be possible to fix it without further disassembly.

If you need a compression tester Andy, let me know and you can borrow mine.

Andy how did it start before this issue? Did it fire up easily, on both cylinders straight away? Or did it cough and shudder into life with lots of white smoke (firing on one cylinder first, before sufficient rpm to get the second one firing). Seems almost certainly low compression and my thinking is that one cylinder could already have been low on compression with it starting on the other one, and now the other one has a problem (stuck valve or whatever) hence the no-starting. Or Tantrum Tony's theory about timing slippage I suppose.

From what I can remember, Ricco, isn't much brighter than you are, . . he seemed to think he could speed the job up by getting the engine lifted out several days ahead of delivery of the one and only part - the head gasket - that wasn't available off the shelf anywhere in the country and was on order at the time. All he achieved by doing that, however, was to put himself in line for paying extortionate hourly labour rates to have his engine stripped and re-assembled by someone who, like you, was too stupid and/or sloppy to think it worthwhile finding out why it had gummed it's rings up in the first place.
