Karl darling

It did cross my mind to do that ex brummie dependant on the price of the lift pump but for £45 I'd rather keep things standard

Lol yeah well that's normally how my repair attempts go, but I'm pretty confident this time. Will definitely post and let you know .

Update on the diesel in oil problem. I removed the lift pump from the engine block, keeping the fuel lines attached i repeatedly pressed the plunger in on the back of the pump and guess what ......... diesel poured out from around the plunger! So there's the problem! Unfortunately you can't buy a diaphragm you have to buy the full pump, £75 plus postage from the dealer, fortunately these engines are used in tractors and generators and on lots of different size kioti and Kubota engines. I think it must be there standard lift pump, anywho I managed to pick one up on amazon for £45 delivered on 8th oct, result! Thanks to all of your advice that lead me to the diagnosis, it's much appreciated. 👍 Spot on advice Tracy thank you 👍

Excellent advice, thank you, I don't know why I didn't think of it before. It is as you said a kioti. The specs don't match any in the links you put up but I will keep digging and see if I can find out. Maybe that power output is specifically made for canal line 🤷🏼‍♂️ it is naturally aspirated. Thank you The base engine is a kioti, thank you Peter, I'll keep looking see what I can dig up on them

Kind of teaching me to suck eggs yes, I'm familiar with engines, servicing, maintenance ect ect sorry should have made that clear from the start, just not familiar with diesel engines particularly canal line 52 which I can't seem to get any information on online, it's like a closed shop. But quite right to point these things out cuthound, we all have different levels of ability and it might help other people reading this topic Thank you Kind of teaching me to suck eggs yes, I'm familiar with engines, servicing, maintenance ect ect sorry should have made that clear from the start, just not familiar with diesel engines particularly canal line 52 which I can't seem to get any information on online, it's like a closed shop.

Thank you Tracy I will look into that

Hi, can anyone tell me if there is such a thing as a canal line 52 workshop manual or help with this problem. I have a canal line 52, 2018 with 440 hours fitted in a widebeam. The problem is the oil level increases when the engine is running, approximately half a litre over 2 hours of about 3/4 throttle. I am pretty sure diesel must be getting into the oil some how (although there is no smell) and obviously this will thin the oil and potentially ruin the engine. There is no coolent or water ingress and no sign of emulsification in the oil. I have been in touch with canal line engines and they were not much help. I have had this problem since the engine was new, but being new to canal boating and canal engines I didn't pick up on it untill the warranty had run out, which canal line were only too quick to point out. The engine otherwise works as it should, starts easily with no smoke, runs smoothly and oil pressure is around 50 psi cold dropping to 25 to 30 warm, when the oil is thinned the pressure drops to 10psi and the warning light comes on. Hope someone can help or point me in the right direction as I can't find any info on these engines. Regards Karl
