Many thanks for all of your suggestions. It's looking likely that there is a faulty oil check valve in the sump which is allowing the oil to fill up in the crankcase from the back tank when the engine is not running. I can't find any parts available for that part of the engine but I will keep researching it.
I had wondered when you removed the lower cylinder why there was so much oil in the crankcase, so am I right in assuming the engine is effectively a dry sump unit with a "built in" oil tank in a similar way to the Royal/Indian Enfield bullet engine?
don't lett anybody tell you how you should do your video's ,just do as you like it ,there is always complaining people on youtube and mostly people that don't make video's ..greetings from holland
well said mate, he does like to know what people think though. i am sure by now he knows he cant please everybody but i bet he does like to see some of us supporting him like you did ;)
Agree, your space your time and effort. To do what you do and not explain along the way would be difficult to do. I have a vision of you doing mime showing the paper specifications and pointing to the rings etc. Please keep up the great work and explanations, I look forward to your videos and continued commentary.
I actually enjoy it. At first it surprised me because when I found this channel all I seen was the one's without him talking but I enjoy him talking about what he is doing. Especially when he he describes what he is fixing to work on.
“Wet sumping of dry sump engine”. Dry sump engines are ones where oil is contained in a seperate oil reservoir (in your case the back tank) rather than in the engine sump. The engine driven oil pump has two sections, one to take oil from the bottom of the oil reservoir and pressure lubricate the bearings and the other is a ‘scavenge’ section that is normally of greater flow capability, that scavenges the oil that has lubed the bearings and made its way down to the sump, back to the top of the oil reservoir. There is normally a simple lightly sprung check valve that opens under slight suction to allow oil from the bottom of the reservoir into the inlet side of the lube oil part of the pump. This valve may be faulty, sometimes debris holds it open thus allowing oil to seep from the tank into the sump through the pump. ie., ‘wet sumping’. British classic motorcycles are notorious for wet sumping. When left standing for more than a couple of weeks, the crankcases accumulate oil. The remedy is to drain the oil that has seeped into the sump, into a clean container prior to starting, this accumulated oil is then poured back into the oil tank. But then I’m sure you have deduced all that, so here endeth the unsolicited sermon....🇦🇺
Absolutely, as soon as he mentioned the drain on the external oil reservoir I was thinking it was leaking out into the crankcase.. either from sitting too long or from a failed seal or something. Either way it seems the dry sump is more likely the culprit here than rings or valve guides. About to watch Part 2 so we'll see if he addresses the sump. 😉
I actually enjoy your narration, it's very informative without trying to be a big personality. Don't ever worry about talking in your videos. Thanks for doing these.
Your mechanical skills notwithstanding, the running narrative you provide offers a necessary context to the work you are performing and authenticates (not that it's needed) your bona fides. Another interesting project....best wishes and be well old mole!
I love your commentary. You are very knowledgeable in your craft. I find the subject matter very interesting. Iv learned a lot about small engine repair from your videos. Thank you!
As someone who knows nothing I appreciate your talking and explaining things. I can understand why those more knowledgable prefer just to watch you work. I enjoy that with some of the tool restoration channels but being selfish I appreciate your explanations in this instance.
I have fixed lots of small diesel engines when they are hydro locked. A lot of people think that pouring oil down the air -intake will winterize the engine, but it locks up the engine. All you need to do is take out the injectors and spin the engine over to blow the oil out. Then pour diesel down the intake and spin the engine over until it blows clean. Then reinstall the injectors and start it. It will smoke like crazy until it burns the oil out of the muffler but after that, they run great. It sure saves on gaskets, time, and money. But that wouldn't make for a good video.
I love the dedication that you take simply to keep your hands out of the way! Talk away, anybody willing to make a video this good can do what they want! I love your videos.
I have a hunch, as a diesel mechanic. Be sure to check and see if the oil tank on the back of the engine has a check valve in the bottom hose. If it does, replace it. Honda 400EX ATVs have a similar setup. An oil tank that you have to check after you've started the engine and filled it back up. If you don't, it will show empty because some of the oil runs back into the bottom of the crankcase. Just a thought. Looking forward to seeing this thing come back to life with ya. Happy wrenching from me in Southern Illinois, USA to you.
I like your narration ,its clear , concise and articulate. Very informative collection of videos. Your passion is evident and as a result, lots to learn for all of your subscribers. Thank You .
I generally hate it when people talk in restoration videos. But you talk about the project, and explain things. And not all about yourself or about nonsense. And I find your voice calming
don't worry about complaints, some people are never happy, I do just wonder why they don't just move on and watch another video!! For me your commentary is interesting and invaluable as it helps to understand what your doing and why and how different things affect the engine, it makes learning about how engines work much easier!! Keep up the good work Dagger and thankyou for all the hard work and effort you put into your videos!!
Personally, just my opinion I prefer the commentary. I also appreciate how clearly you explain things. Completely understandable for some of us who aren't so well versed in small engines. So, thank you.
This appears to be a dry sump engine design. My humble opinion thinks the problem could be oil seeping back into the crankcase from the oil tank while setting. This would cause the crank case to be overfilled with oil. This would cause the engine to hydro lock on the lower cylinder. Just my thought as I watch you work and I do enjoy your commentary.
My guess as well, especially because there is so little info on the vertical shaft engine - there is no way that much oil could get past the rings unless the crankcase was full of oil I'm pretty sure that some twat way overfilled the oil tank
Probably there´s a check valve to keep this from happening and this valve is faulty. Maybe they used the oil pump valves for that purpose and they don´t work well anymore
You're a very matriculate worker but I beleive you took apart more than needed. Never should be that much oil behind a piston which is why it was hydrolocked.
exactly what I was thinking as well, only reason I can think of for it having an oil tank on the back, and as also already suggested, the one way valve must be worn and leaking oil back into the crankcase.
Even the cross-hatch pattern in the cylinder was still intact. Aside from the mess, everything looked new in there. This doesn't appear to be a piston/ring/cylinder problem. Overfilled? Stored on a decline? Looking forward to this mystery being solved.
Overfilled or its been stored on its side somehow allowing oil to move into the exhaust and inlet , just a guess? ,anyway hope its a simple fix for you,ATB Matty 😀
"I want a diesel lawn tractor, but I want it's engine to include that cylinder oil flooding problem that was common on World War I era radial aircraft engines" Ruggerini: Say no more.
Really enjoyed this video. I’m from USA and I have never seen or realized diesel mowers exist. Talking is very welcome for me. Not expert enough to common on oil in cylinders except to say I used to keep my smaller mower stored in winter vertically and it had this problem so my first guess was it was stored on a hill. As to draining oil, I always use a pump suction siphon kit for doing oil changes now. It’s slower, but much cleaner than fussing with drain plugs. I don’t even spread towels at all anymore. Don’t know if they have in UK, although mine is French so it must be in Europe.
So if you look at my history I almost never comment on a video, but I feel like I needed to type this out. Please keep up with what your doing! Your videos are fantastic and you do an amazing job at narration. While subtitles are nice hearing you explain aloud how something works helps bring a better understanding to the video
I can get a riding mower in the USA for $50, or $10 for a push mower at garage sales. I sell them for 400 (100 for a push mower) and offer $10 for a trade in. That's single cylinder gas mowers. So I can make 100 for 4 or 5 hrs of tinkering and about $5 for a gasket and some fuel, oil, etc - it depends.
Wow , I am so amazed at how technical this video is. I have not one ioda of mechanical ability. However, you have just thought me so much in these few minutes. You have just earned you a new sub . Ty. Can't wait until I see this engine running. Ty
When I bought my latest house it came with a Westwood t1200 from 1983. I have a robot lawnmower so no need for the t1200, a very over enthusiastic guy bought it from me for £450. It was still running and cutting but you could tell it needed some work. I was just happy to have the garage space.
Your narration is really good and makes the videos better if anything. More and more channels are doing the restoration + subtitle only formula, but very few have good narration as well. Almost no one.
Honestly, you have the formula figured out quite perfectly. You do silent/subtitled videos on the projects where that is the most effective/informative/entertaining way of presenting and you narrate on the projects that require a more detailed explanation or an explanation that would be too long or cumbersome to type out (and the viewer to read.)
Ive rebuilt a few of those ruggerini diesels and was surprised at the quality of those diesels. Great job, thanks for the videos. Greetings from the states.
Your videos are amazing how they are the explanation throughout is brilliant. Thank you for sharing the restorations you do please don’t change anything.
I feel like half of the point of this channel is the previous owners not doing a good job of taking care of their machines. Can’t get too mad if they don’t tell you it’s hydrolocked. Probably didn’t even know it was a thing to tell. Not that I’m defending the twit. Just saying. Also never stop talking. You are the best.
Nice to see the diagnostic process ongoing given you were confident of the piston rings and they turned out to be good. It'll be interesting to see where you go from here.
I really enjoyed your explanations! I like your videos with commentary much better, I like to get to know more about the things you're doing and the reasoning behind it. Keep up the nice videos
Personally I have absolutely no problem with your talking. You know what you are talking about and that shows. Additionally you are a Brit of one stripe or another and your accent is pleasing to the ear. Keep on keeping on sir. Thank you for the entertainment. I am NOT a diesel mechanic. I have been a gas engine mechanic for 65 years. ( I'm 81) but I understand diesels enough to follow along quite handily.
i personally like the talking, you explain what you are doing and potentially what is wrong. very informative. I get lost when you dont talk, even if i read the captions. It's just not the same
Don't listen to the haters! I think the vast majority of us like it best when you are narrating the videos :) We understand a lot more when you are talking.
I don't commonly work on Diesel small engines, but in big diesels, diesel "runaway" occurs frequently when oil finds a path to the combustion chamber. It's a good thing this never happened. Also I should really say that I love the "talkie" versions of your videos most. The silent film ones i find less informative, and I'm not just here to be entertained, I actually pick up something new now and then and I run a lawn mower flipping business (i buy derelicts and refurbish them). Narrated is the way to go. Thank you.
In all honesty, i prefer narrated videos. I tend to have these in the background while i working on something, so listening along to whats going on is nicer than reading subtitles. I know lots of people like the restoration in its purity, but I think a mix of both is best.
Thank you for sharing this engine teardown, I agree with some of other comments that probably overfilled on oil. I suggest to replace rings and seals,gaskets etc. for long life repair. Thank you.
I said it before, and I'll say it again. I prefer narration, or voice over. It reminds me of being in the garage with my grandfather when I was younger, and how he'd explain to me what he was doing
Nice job and explanations for an engine never seen in the USA. One thing I might suggest is to use a thinner fluid than diesel to do a leak-down test. Gasoline or ethanol. If it will contain the thinner fluid it will certainly keep the oil where it belongs. Be looking for Part 2.
You mentioned an oil tank, so I assume we have a dry sump system, which is common in a vertical or radial engine. Also a common failure of a dry sump system is a leaking check valve on the oil return line from the crankcase to the oil pump / oil reservoir. Some systems use crankcase pressure to return oil to the tank, some use a pump. In both instances there will be a check valve somewhere in the line to prevent oil from gravity flowing back to the case when the engine is stopped. Over time, if the check valve is leaking, the bottom cylinder will fill with oil that has leaked into the crankcase. The piston rings won’t stop the oil, it will seep into the cylinder given time. Eventually leading to hydro lock. I believe your rings are fine. Good luck and enjoy your channel. 👍
That has to be a dry sump engine otherwise oil would get into the bottom cylinder after sitting a day or two and lock it up. It may even have a *defective drain back valve* because there was just too much oil in the crankcase. There is a reason it does not have a case drain, it's because there should not be much oil in the crankcase ever....Make sure the scavenge pump is working correctly just in case...
Really enjoyable video. I enjoy your commentary and you are good at explaining what you are doing. I have never seen any of those diesels here in Ireland and that one sure does need TLC. Great video and thanks for sharing.
Looks to me just been over filled with oil seeping past when engine is at rest didn’t see u pull the dip stick normally first port of call then go from there and yes I am a horticulture enginner of 45 years
The dipstick showed half way between low and high. I think the issue is the oil check valve allowing oil to leak back into the crankcase from the rear tank
Great video your talking is good that's how we learn don't worry about other people there not got the balls to make videos like you thank you for making & sharing your work keep well & safe Regards Steve UK London
Never seen a diesel in that much detail before, pretty cool. (And, never seen an inline 2 cylinder engine...) The mystery problem is always frustrating!
Wow I really wish one of these was available to find here in the states. I would certainly purchase one. Back in the early 80's we had an Italian tractor that was diesel for our fruit orchards. It was a very low height tractor that was articulated and four wheel drive that I would still like to find. I was in my 20's back then and wasn't such a tractor fan. It had a common Italian equipment name.
Just found your channel. To those who complained about you talking during the video piss off. It looks like the hydro-lock may be caused by a high oil level as shown when you removed the lower cylinder. Oil poured out of the crankcase. If it is high enough it will sit in the cylinder behind the piston it could seep into the combustion chamber if sitting long enough. I am looking forward to the next video and will check out your channel.
I enjoy the videos as you have been doing talking and all don’t let anyone tell you how to do your videos you’re fine as you are sir. Very informative very appreciative sir.
Let me just add my voice to the pro commentary group it does add enjoyment to the viewing and helps with understanding the engines. That's why I watch your content. Thanks👍
Last time i looked this was your channel. So you get to run it the way you feel most comfortable so i wouldn't worry too much about what other people say. I say just do it your way and leave it at that.
You can better cap or tape off the connection to the injector, if dirt gets in there it can block one of the little injection holes. I also think you are right about the oil level in the sump getting too high and therefore it can seep past the rings and fill the bottom cylinder while at rest.
Firstly.. talking is not a problem... adds to the interest . As for the reason for oil I would have thought from what I have seen up to now that the only way that much oil could get in was from overfilling... When you take out the bottom barrel on a vertical motor the oil level should be below where the piston travels.
Had one of these best mower I ever had, would run forever on a tank of diesel. Much cheaper to run than the petrol equivalent. It also would mow and collect anything, however long the grass was!
Many thanks for all of your suggestions. It's looking likely that there is a faulty oil check valve in the sump which is allowing the oil to fill up in the crankcase from the back tank when the engine is not running. I can't find any parts available for that part of the engine but I will keep researching it.
hey dagger hope your well
You had me thinking that someone swapped in horizontal shaft parts to “make it run” and the Frankenstein method failed miserably.
I was gonna say it was overfilled with oil, but I think that's a more solid explanation. Plus you know what you're doing
I had wondered when you removed the lower cylinder why there was so much oil in the crankcase, so am I right in assuming the engine is effectively a dry sump unit with a "built in" oil tank in a similar way to the Royal/Indian Enfield bullet engine?
Just more excuse to have a damn good investigation into the engine!
don't lett anybody tell you how you should do your video's ,just do as you like it ,there is always complaining people on youtube and mostly people that don't make video's ..greetings from holland
well said mate, he does like to know what people think though. i am sure by now he knows he cant please everybody but i bet he does like to see some of us supporting him like you did ;)
Agreed. do your video as you like!
Exactly!
Agree, your space your time and effort. To do what you do and not explain along the way would be difficult to do. I have a vision of you doing mime showing the paper specifications and pointing to the rings etc. Please keep up the great work and explanations, I look forward to your videos and continued commentary.
My shop my video my rules. We are moving on.
I'm glad you talk. I've actually learned a lot from you and I couldn't of learned unless you talk. Lol
For those who don't like the talking, there's always the volume control. Customize your experience, and quit bitching.
I really enjoyed the thorough explanation while you were disassembling this engine.
Why is it that people have issues with him talking about whats going on with the projects? I have no problems at all with it personally.
Yes me to
Because ppl have to cry about something
Its very educational and a great way to learn new things. Its way better than the music ones. He explains what and why.
I agree I like the commentary personally, it doesn't distract from the project unlike others where I have to read what's going on
I actually enjoy it. At first it surprised me because when I found this channel all I seen was the one's without him talking but I enjoy him talking about what he is doing. Especially when he he describes what he is fixing to work on.

This is actually pretty cool, Thanks for the learning session dagger. Love this informational vids
Thank you for sharing this engine teardown, I agree with some of other comments that probably overfilled on oil. I suggest to replace rings and seals,gaskets etc. for long life repair. Thank you.
Glad you talk. Really enjoy your narration.
Keep talking!
I watch these videoes to learn something, AND be lightly entertained at the same time. This you provide for.
I said it before, and I'll say it again. I prefer narration, or voice over. It reminds me of being in the garage with my grandfather when I was younger, and how he'd explain to me what he was doing
I really enjoy this style of your vids! Thanks.
Nice job and explanations for an engine never seen in the USA. One thing I might suggest is to use a thinner fluid than diesel to do a leak-down test. Gasoline or ethanol. If it will contain the thinner fluid it will certainly keep the oil where it belongs. Be looking for Part 2.
You mentioned an oil tank, so I assume we have a dry sump system, which is common in a vertical or radial engine. Also a common failure of a dry sump system is a leaking check valve on the oil return line from the crankcase to the oil pump / oil reservoir. Some systems use crankcase pressure to return oil to the tank, some use a pump. In both instances there will be a check valve somewhere in the line to prevent oil from gravity flowing back to the case when the engine is stopped. Over time, if the check valve is leaking, the bottom cylinder will fill with oil that has leaked into the crankcase. The piston rings won’t stop the oil, it will seep into the cylinder given time. Eventually leading to hydro lock. I believe your rings are fine. Good luck and enjoy your channel. 👍
I'm glad you talked in this vid
That has to be a dry sump engine otherwise oil would get into the bottom cylinder after sitting a day or two and lock it up. It may even have a *defective drain back valve* because there was just too much oil in the crankcase. There is a reason it does not have a case drain, it's because there should not be much oil in the crankcase ever....Make sure the scavenge pump is working correctly just in case...
Really enjoyable video. I enjoy your commentary and you are good at explaining what you are doing.
I have never seen any of those diesels here in Ireland and that one sure does need TLC.
Great video and thanks for sharing.
I for 1 appreciate your commentary! S the camera follows what your working on keep it up. Thank you
great vid i like restoration videos with verbal explanations in them
Just subscribed can't wait for part two. Interesting engine. Thank you for not adding music, I enjoyed hearing you work.
Looks to me just been over filled with oil seeping past when engine is at rest didn’t see u pull the dip stick normally first port of call then go from there and yes I am a horticulture enginner of 45 years
The dipstick showed half way between low and high. I think the issue is the oil check valve allowing oil to leak back into the crankcase from the rear tank
@@MachineryRestorer I’ve got a Westwood w11 and I’m wanting to do it up how hard is it to re do ?
Great video your talking is good that's how we learn don't worry about other people there not got the balls to make videos like you thank you for making & sharing your work keep well & safe

I like talking and explanation. Keep up the good work. Looking forward to the detective work on this engine
I prefer the videos where you explain what you’re doing, what you find and how you fix it personally
Great video thanks for sharing that is a Nice little diesel there I have a Pasquali 997 with a Ruggerini Engine in it currently restoring it.
I really like the videos where you talk, I honestly prefer them over the videos where you don’t talk. Its much easier to learn from you when you talk
Never seen a diesel in that much detail before, pretty cool. (And, never seen an inline 2 cylinder engine...) The mystery problem is always frustrating!
I like the talking, it's very informative and I learn a lot👍 great video, looking forward to the next one.
Wow I really wish one of these was available to find here in the states. I would certainly purchase one. Back in the early 80's we had an Italian tractor that was diesel for our fruit orchards. It was a very low height tractor that was articulated and four wheel drive that I would still like to find. I was in my 20's back then and wasn't such a tractor fan. It had a common Italian equipment name.
Just found your channel. To those who complained about you talking during the video piss off. It looks like the hydro-lock may be caused by a high oil level as shown when you removed the lower cylinder. Oil poured out of the crankcase. If it is high enough it will sit in the cylinder behind the piston it could seep into the combustion chamber if sitting long enough. I am looking forward to the next video and will check out your channel.
Cross hatching in that cylinder looks good.
Maybe it was just way overfilled.
I like the explanation.
Don't ever stop talking during your videos. If you don't talk, we don't learn. Love your content and learn a lot. 👍
I enjoy the videos as you have been doing talking and all don’t let anyone tell you how to do your videos you’re fine as you are sir. Very informative very appreciative sir.
Great video again 👍 super cool to see a diesel like this.
I love your vids, I like it when you explain things. You do you, make the videos the way you want to. The haters can leave.
Im in the USA, i had heard of Westwood but never a diesel version or even that brand diesel. Great vid, thoroughly enjoyed it.
you poor prune, being there!
Let me just add my voice to the pro commentary group it does add enjoyment to the viewing and helps with understanding the engines. That's why I watch your content. Thanks👍
Last time i looked this was your channel. So you get to run it the way you feel most comfortable so i wouldn't worry too much about what other people say. I say just do it your way and leave it at that.
I learn more from people talking. I enjoy watching you work on mowers we don't have in the states
It's in lovely condition. Nice find!
You can better cap or tape off the connection to the injector, if dirt gets in there it can block one of the little injection holes. I also think you are right about the oil level in the sump getting too high and therefore it can seep past the rings and fill the bottom cylinder while at rest.
What a clean Westwood ,great episode 👍👍
Firstly.. talking is not a problem... adds to the interest . As for the reason for oil I would have thought from what I have seen up to now that the only way that much oil could get in was from overfilling... When you take out the bottom barrel on a vertical motor the oil level should be below where the piston travels.
Had one of these best mower I ever had, would run forever on a tank of diesel. Much cheaper to run than the petrol equivalent. It also would mow and collect anything, however long the grass was!
