Ok, thanks again.

Hi Tony can you recall the size of the washers on the banjo bolts on the fuel pipes in the engine, I thought it might be worth getting some in just in case.

Will certainly keep a much closer eye on it in the future. Thanks

An update and I'm a numpty. Went back to the beginning checked oil level again on closer inspection of dipstick I noticed a watery film above the level marks, so withdrew about q/2 a gallon of clear looking oil and let it settle low and behold mostly water, shall drain the crankcase completely tomorrow and refill with fresh oil. The engine bay deeply flooded last year and again during lock down and I didn't think that the water could have gained entrance into the engine. I assume this had been over pressurising the crankcase causing valve cover gasket to leak. Unless someone has a more experienced view. Thanks again for input.

Thanks for the tip Tony will check tomorrow, thanks again for advice.

To be honest the gasket didn't look in too bad a condition it lifted away in one piece on the leaky side. The fluff looked like a small collection of fibres matted with oil, I suspect possibly drawn into the inlet manifold in the past as it didn't have an air filter element when I first got the boat. I've got 2 sets of cover gaskets so will try resealing to see what happens.

No I ment the breather tubes when took them out to check clearance the external sides of them had a lot gummy coating. Tony it is possible that the fan had thrown oily water up to burn off and I suspect there has been an unseen leak for a while though I can't say I've noticed much of a drop in oil levels. But it's the puff of smoke and spray of oil from no 1 cylinder that concerns me.

I'll do that next, hopefully weather will be clear tomorrow. Thanks.

Hi guys d sorry for slow response but was only able to get to the boat today. I checked the breather tubes a and they were all clear. So any ideas as to where to investigate next. One thing I did notice was the out sides of the tubes that screw into the cylinder heads were a little bit gummy with oil and bits of fluff.

Unfortunately I've not been able to get to the boat if weather decent tomorrow I'll make a start. Thanks for all advice you've given me hope that it would turn out to be a relatively simple job.

Thanks again guys for help. They all s seem to be leaking but it's No1 that's actually spraying the oil out at the same time as a puff of smoke from the rocker cover gasket and hits the bulkhead. 2 and 3 not so obvious but must be leaking a fair amount as you can watch a constant pinging of oil off the crankcase oil fill cap but I can't see signs of a drip onto it. The amount of smoke coming off the hot engine looks very dramatic.

I've not noticed observed oil level rising but I will check again later today. One thing I didn't mention was that the oil spray and fumes are are not continuous but pulse, I assumed with the exhaust valve opening and closing if that makes sense.

Thanks for the advice Tony I will start of as you suggest. I came to my conclusion because of the way oil and smoke are blown out under pressure and assumed the valves and guides were leaving pressurised exhaust into the rocker covers and then spraying oil out under pressure.

When I said major overhaul I meant the top end. Basically it is spraying oil and fumes from rocker cover gasket. So assume cylinder heads need at minimum a decoke and all new seals up to possibly replacing valves and guides.

Problem is getting someone to come out to the boat.

Modded up in maple at present. Moored not modded.

I have the workshop manual.

I have strpped and rebuilt an engine in the past. I wanted to check about the tools as the parts manual only talks of 4 spanners and obviously the various fastenings are listed and are covered by said spanners but I was just making a general query as 4 spanners doesn't seem much.

Thanks for reply guys. I don't recall reading about bump clearance in the engine manual, what exactly is that. I'm having to consider doing this myself as getting hold of a mobile engineer on the Macc and peak forest canals isn't easy. Hoping to have one guy but he's had an accident and I'm not sure when he will be fit. I'm on a48 hour mooring but been given permission to stay for 4 weeks and I'm already 2 weeks into that.

I've found open ended spammers the worst never seem to get rid of them. As for spanners the are still available, apparently the ST3 used to come with for of them.

Hello all It looks like my latest ST3 needs a major overhaul, in your opinion can this be carried out using the 4 spammers Lister in the parts manual or will a socket set be more use. Thanks.
