andyandsallyb Posted September 22, 2010 Share Posted September 22, 2010 Hi Everyone, Just wanted to know if any of you have had any engine work done by Calcutt Boats? They seem to be highly recommended, I spoke to one of their guys today and he certainly made all the right noises. I am considering having my BMC 1.5 rebuilt next year and have spoken to a couple of the broads based yards but the cost differencial between them is crazy. My engine sounds sweet enough and starts very easy but has a problem running off load by where it continually puffs blue smoke. The only way to cure the problem has been to advance up the pump timing but the downside to that is the inducement of a hideously loud diesel knock - equally undesireable. It has been suggested that the issue could be with the timing chain and sprocket gear being streached and excessivly worn, but Herbert Woods have very little service information for our boat and so this is an unknown. I am planning though to renew the chain, sprockets and associated tensioner as this is a fairly low cost option. If it proves to be unsuccesful then maybe the rebuild rout is the answer? - Any thoughts?? ! Andy Quote Link to comment Share on other sites More sharing options...
