I'm Siren, and I sold my house to buy a 1976 Tayana 37 (CT37) Taiwanese build designed by Robert Perry. She boasts a teak deck, roomy quarters, and needs a lot of work, and the projects have begun! I'm traveling solo with my rescue pigeon, a small tender, an iffy outboard, and my rigging can not be sailed.
I'm a surfer, yacht broker, captain, diver, and Floridian who has already spent years working on sailboats and yachts, and I've traveled the Caribbean and beyond, living in countries around the globe, and now I'm here to do it over again on my bluewater boat. Join me as I get her ready!

Good to see you back on your feet Miss Siren. Keep the videos coming and stay healthy.
Thank you!!!!🙏🏼
Siren, it you truly ran that engine out of oil you may want to at least take the oil pan off and look at the rod and main bearings to see if they've been hurt (scored). If you just got the oil so low that it didn't show on the dip stick you're probably OK. Another way to check, and this is probably be better way in your case, is to take the oil filter off and cut it apart (they make a special tool for this). If there are metal shavings in the filter you have a serious issue. If there are just flakes that you can't feel between your fingers this is normal wear and nothing to worry about. I think your friend is on the right track with the coolant leak. Keep the good stuff coming.
Thanks! Yeah, but at least it wasn’t like it ran for long like that. I was watching the gauges and shut the engine down as soon as pressure dropped, and Daren checked the oil I believe at the start of each day, so we were fine until something happened suddenly. I’m assuming it’s a gasket just due to the fact the engine now has over 4K hours on it.
Look at Sailing Magic Carpet and talk to Aladino an Maya about external Chain plates they just completed their Cape George 36 and moved all the chain plates to external due to leakages that rotted the deck beams.
I have to be honest, I really dont watch youtube or the other sailing channels, but people keep referencing them as they tend to have a lot of the same problems that I have! hahah They're deck! I was sent a video where they did the deck too, I think. ....I think. I guess I'm going to have to poke around their channel. Luckily, Anderson if the guy for the chainplates. I'm going to have to feature that on a future episode. I've searched all over the internet to see other boats and what they look like after doing it, and I've been so many in person, and honestly, I dont love any of it! I just dont want to cut into the wood. Thank God, Anderson is not only a master sailor but a VERY impressive woodworker, and he did the job on his boat, and after searching and searching to find someone who had done a "good job" that I liked, I finally just looked at Andersons, which I'd seen countless times and had never really paid attention to, literally a few blocks from my house, and his were BY FAR, the most impressive thing I've seen so there's no way Im letting anyone else touch the boat when it comes to installing those new chainplates. He put teak under them. I'll have to do a video!
@@TheSirensLog Another reason it might be worth giving Aladino and Maya over at sailing magic carpet a shout is I believe the chain plates they installed externally on their cape George are designed for a tayana 37.
Best of luck with the reseal. My WAG is previous ownership neglected to run the engine on a regular basis which caused seals to dry out. Hopefully you can resolve the engine issues without breaking the bank
Using diesel to clean up the crank case is the go. Then make sure you run it with fresh oil warm it up. Then dump that oil. The diesel in oil is hard on your seals. If you have an oil cooler pull it out and pressure test it. That’s a simpler fix.
He sounded like a wealth of knowledge. He also seems like a kind soul….which to me means he is something that should be caught and kept
LOVE the thumbnail!!!
Hahahah.... So these thumbnails. lol The best way for me to get them, alone, is to shoot video and then slowly go through it and take a screen grab of the frame I want. This video was like 4 whole minutes of me posing and making faces with a dipstick. hahahaha It was probably the most hilarious video I've ever had to go through alone, of myself, just to get a thumbnail.
@ That is hilarious! I think you should show us the whole 4 minute video!
You can do a comedy show with that guy
Sounds like an oil cooler if there is oil in the water , vice versa is probably a head or head gasket

Good job!
Thanks!! Thanks for being here this week!
I would suggest you mixed synthetic oil with mineral oil, I would first of all flush the engine, pressure test the cooling system,
We were careful not to do that, actually. Did did mix various viscosities, though. It was around 50 degrees in there so I think the cold was the most likely culprit.
Good video….boats, always something uh? Engine issues I am seeing described - head gaskets and valve cover gasket are straight forward. You do not need a new Yanmar. But, time to bring in the proper Yanmar techs with the correct tools. Love the heated vest…chilled down here in Stuart! Thanks, Andrew
Yeah, it’s time to get it fixed! And you’re right, I can always get a new engine, but that’s not really ideal at the moment! A good mechanic will cost $175/hr so the trick is coming up with the money quick enough.
Very important projects!!!you will do your best!!
Gonna try!
N0 matter what, Boat 🚢 life is always an adventure. And it is never boring. There is always something to fix or do. But ! The Boat can take you to places no one else can go.
So, with that said, I would like to wish you a Very Merry Christmas 🎅 🎄 and Happy New Year 🎉!
So until next time, Aloha from the Big Island of Hawaii!
I hope to see 👀 your sails ⛵️ on the Horizon someday from our lanai.
Aloha and Cheers 🍻
@@kptbillburkett8735 Thank you!!! Merry Christmas!!! 🎄
Your not that dumb are you who told you to taste it
@@daveallison1888 Thats a common technique to determine exactly what is mixing with the oil so you know where the problem is coming from.
@TheSirensLog i have worked on vehicles boats never tasted it
I know what to do in your case (on the cheap), but it’s way too much to type out on here and most will bash the advice (but it fng works)… Smell can determine just as well as taste.. I never 👅. Don’t bother with a diesel flush. Women, by the way have a better sense of smell than men.
I been watching you for a long time and all I can say is you should merry the engine guy!
You mean marry
Siren, sweet pea, ur just going over what we already know needs fixing, as u said, gotta get started somewhere!!!! The cosmetic stuff can wait, gett the engine done, get the rigging done. Come on Woman pick up the ball. Have great Xmas an N.Y. 🇭🇲💯🤣
Merry Christmas!!! 🎁
Yep, things have just been a bit hectic, complicated and stressful lately but it’ll be alright. I need to get the engine fixed asap but if I hire someone it’s going to be thousands!!
Hi Siren😀
You may have 2 seperate problems.
So i suspect, if the oil cooler that is cooled by the salt water failed and allowed the higher pressure oil to leak into the cooling water ( from a failed/internal split in cooler) the oil would quickly get pumped out with the cooling water into the exhaust and out back of boat .
This is a different problem from the milky oil that is probably the fresh water/antifreeze cooling pump seal leaking into the oil. Or the head gasket leaking coolant into the oil, the head gasket does many jobs including sealing the combustion chamber. I suspect the pump because no oil in the coolant.
But check by taking a glass jar of coolant and see what separates out after 24 hours.
You have 2 seperate problems , possibly the oil cooler issue is intermittent….
Cheers Warren
How many hours are a lot of hours? We were a Yanmar service center at the boatyard, I have seen 10,000 hour Yanmars still running well. Get that milkshake out of the motor and fill the crankcase with Kerosene & new filter. Pull the injectors and spin it with the starter. Change and repeat a few times. I’m betting on the heat exchanger.
@@boyddubard4197 yah I agree but am wondering why it was out of oil so fast after checking level. Can failed head gasket pass oil going to valve train to cylinder on this model Yanmar?
But had those 10,000 hour engines never been rebuilt?? I agree a well maintained yanmar can last an incredibly long time, hours or years, but the engine is around 25 years old, pushing 5000 hours and hasn’t been rebuilt. Would the gaskets be going bad anyway?
I agree with asking this question. The way it happened was a bit strange to me. Ran 24 hours no problem, gauges reading good, oil level good, no milk, just sheen on the water from exhaust. Then ran it again for maybe an hour at best, oil pressure tanked suddenly, and all the oil was quickly gone. Refilled with oil, tried again, 30 minutes later oil pressure tanked again but this time the oil was still there, but clean. Got towed the next day, in Carabelle I ran it at the dock for maybe 20 minutes and then the oil was full of apparently coolant and milky.
@@TheSirensLog yah that’s kinda a mystery to me. The oil I saw in video was clearly whipped good which means it had ran for a while to get infused like that. So how much oil did you have to add when you added oil the first time?
@ it’s very possible to get 10k out of a good diesel motor. That usually dosent include fixing oil leaks because of a gasket or seal getting had and leaking. That 10 is pretty much just the main block of the motor in other words the motor can stay in boat without removal for rebuild. It may or may not not include head gaskets, valve job, injector and pump renewal. You should have cleaned and and or replaced the heat exchanger and oil cooler many imes in that 10k timeframe. Also don’t forget the yearly raw water pump impeller and exhaust elbow decarbinazation. Something to think about is you can get sea water in the engine if the exhaust gets mucked up. Your guy said it tasted sweet like antifreeze but I’m scratching my head as what I saw on your video is the antifreeze overflow tank was half full and the engine seemed full when the cap was removed. There had to be a good amount of water getting in oil to make it that white. But you’re not very low on water…
The valve cover gasket has nothing to do with the coolant in the oil…. You need to do it right and remove the oil pan clean out all the baby poo oil and replace the rod bearings IF you ran it a long time with the baby poo oil. If your engine has a ton of hours rebuild it if not just re-ring it. You need a good mechanic that has rebuilt a few engines. Not just any backyard mechanic can do it. Replace the oil cooler for sure. The exhaust manifold can leak coolant into the cylinder past the rings so it can be bigger than just a head gasket. Get a coolant pressure tester pump it up take out the injectors and see which one of the cylinder have water. Do not pressurize the engine then crank it with starter with injectors still in as it can hydrolock the engine and bend a rod and cause catastrophic damage. So in short it can be 4 things that leak coolant to the oil. By most common, 1 head gasket, 2 oil cooler, 3 crack in eahast manifold, 4 crack in head or block. The head, block, oil cooler, and manifold cracks usually are caused by freezing of coolant but you have antifreeze in system and you are in warm climate. So probably stress crack or leak and or head gasket failure. When you remove head gasket you can usually see where it was leaking. leaking coolant into cylinder can be verified as the leaking ones will be clean and less carbon on top of pistons because coolant acts like steam cleaner on piston and combustion chamber. Good luck hope it’s just the gasket. Also if you find salt water you must replace the valve springs as the salt will attack newer hardened valve springs causing them to fracture. Don’t think your motor has them just the stand steel ones. But something to check. you need any advice just ask. I’ve been an engine builder for 50 years and would be glad to help if I can.
Thanks for that! I’m guessing gasket somewhere because we never overheated it. Oil was changed regularly and maintenance had been done. The engine has over 4K hours (could be closer to 5k now, honestly, I have it in the log) so I’m sure it was pushing needing the rebuild anyway. It could be as simple as it was just time. I honestly don’t believe it was anything we did, as the engine had no problems until it just suddenly started loosing oil, but at that point, we were watching oil pressure like a hawk and I shut her down as soon as the oil pressure tanked to avoid harm.
@ well it’s gonna need further investigations. You could have broken or stretched a head bolt lots of gasket leaks and stress cracks start for no reason. If your short on cash pull it replace the rod bearings making sure the rod journals are not scored. You can get a lot more hours out of that motor if it was taken care of. You will see what the cylinders look like when you get it apart. First go to auto parts like advance auto parts they will rent you a coolant pressure pump. Test to see what cylinders have water. That helps you know where to look when you pull the head. If no cylinders have water then probably cracked block or head. So when you ran out of oil did you notice the water in the oil? Keep us posted.
Some good advice, but don’t forget this is an engine in a boat it a very big job to ‘drop the pan’ . It requires Complete engine removal which when boat is in the water it’s quite complicated and expensive .
Cheers Warren
An emergency situation loosen the pressure cap you'll lose a little bit down the bildge but less will go into the motor oil
Loved the vest 🙂
Flush out the engine first. You need to get that milkshake goo out of there ASAP. Then pressure test the cooling system.
Forgot to mention, don’t jam that pump tube all the way down to the bottom, it won’t flow
Hi Siren and garrison , how are you all going? I want to say Merry Christmas and a happy New Year to you all you are such a beautiful woman Siren , I don’t understand why a man hasn’t scooped You up, you are such a kindhearted and wonderful person. If I was in America, you have no hope I’d want to be around you all the time. And help you out with your yacht anyway lots of love and appreciation Cliff from Logan city Queensland Australia. I’m on the big island
Awhhh thank you. Yeaaaaah…. It’s tough to find good men these days, too! Hahaha 😂
Regardless of whether you get it rebuilt or repair it yourselves, it will be very helpful to know precisely where the leak is before you actually tear it down. Doing a pressure test on the cooling system will probably help,. A lot can be determined with a cylinder leak test too, but keep in mind that some leaks may only show up when the engine is fully warmed up. Unfortunately, the engine bearings probably took a beating, running it with a mix of water and oil, and your loss of oil pressure is a really bad sign, so unless you find something definitely wrong with an external system that caused all of this, I would plan on getting it fully torn down and properly rebuilt…while it still can be. It will be a lot cheaper and safer to do it now, plus the piece of mind…
Best of luck.
I'm considering replacing entirely. Is that wild? I dont have the money to rebuild or replace, but if a company will sponsor the channel with an engine, that would be the cheapest way, by far! If I do a rebuild, at $175/hr having a mechanic do it, and especially if they want to pull the engine to do it, that wil probably cost damned near as much as the new engine. What do you think?
Re your rigging consult the rigging doctor and others substitute with Dynema rigging .. much lighter and cheaper .. stronger replacable anywhere with minimum special tools and you can carry a couple of drums with you. No corrosion .... Just watch out for rubbing points.
I had considered Dyneema, actually. It's not totally out of the question!
22:20 Is the engine now running?
Maybe head gasket, maybe the head cracked less likely, block cracked even less likely. Also the seal from block to water pump. My engine had a oil cooler, engine oil cooled by engine coolant. If you have one it could be the source, gaskets or breakdown in the exchanger tubes by corrosion or something. Chain plates can be done by a metal fabrication or a machine shop. Check a few for prices, need a template. And changing a head gasket or water pump seal is not a rebuild. First if top end goes bad you change the head, for a rebuilt one. If the lower end being pistons bearings and rings went bad, would be a rebuild. i would exchange the engine,, due to time and tools involved. Make sure its coolant and not fuel, different scenario. Did you lose a lot of coolant. Being you mentioned loosing oil, coolant in oil, no oil in coolant(water pump seal), no oil or coolant in fuel, Could happen at the head gasket. There are some pressure tests for that. In the boat with a gauge and the engine running.
I don’t expect any of that, and I feel like it’s a gasket because gaskets just go bad. We didn’t push the engine and we never had any smoke or overheated or did anything that was “wrong”, but it has enough hours on it that it was nearly time for a rebuild anyway, so I’m thinking it’s just a natural occurrence.
@@TheSirensLoggaskets don't really "go bad". Valve cover gasket, sure, but not a head gasket. Head gaskets are secured with the pressure of the head on the block. They don't rely on rubber to make the seal like an o ring would. Head gaskets go bad mainly with heat. They will either burn / blow through between cylinders or oil galleries or water jackets (think running your engine too hard for too long, extreme exhaust gas temp) or they will leak because loss of that pressure from the head. That typically would be a warped head from over hearing. Unless an engine is known to go through head gaskets due to some engineering flaw, it shouldn't be a maintenance item if your engine is properly cared for.
If your oil is that compromised or it was run without oil for any period of time your bearings are probably damaged and will continue to get worse until your engine locks up or throws a rod through the block.
It's is a full engine out situation. That whole thing needs to be torn down and gone though. Rebuild or replace. Especially if you're going ocean sailing. You can get away with old man duct tape fixed if you're staying coastal (when the engine stands you, you might not be in a deadly emergency situation), but if you're out at sea and you lose the last or need to get out of the path of a storm and the engine decides to go then... You're pretty screwed.
Since you don't have experience successfully building engines, I really don't recommend doing it yourself. Pay a professional to do it, and yes, it may be worth considering a new engine depending on how much the rebuild costs. Don't replace it with a used engine, better to tear this one down and rebuild it so you know the condition of it. If you buy a used engine that "runs" and drop it in, you may be in a worse situation because it may be on borrowed time and you're thinking it will be reliable. Have it pulled and rebuilt or buy a brand new engine.
Talk to some mechanics, get some prices, and go with the one that seems the most skilled and takes pride in their work.
If it were in a car, you could put it on a lift, drop the pan, and physically inspect the rod ends and bearings. If you can figure out how to do that on the boat, that would tell you a lot of very valuable info.
Good to see you again! It's been awhile! How is your pigeon doing? Have a great holiday season! You're wearing an electric blanket! I'm in S E Florida and I'm in my recliner under an electric blanket 🎄😸
Hahaha It’s has been so cold!!! Garrison is doing good. He’s not even attempting to walk, despite my efforts. I think he’s just content to scoot around and it doesn’t seem to bother him. lol He lives a good little life in a house right now, with a big window, and big rugs to scoot around on in the evenings.
@TheSirensLog yep he's living the good life with you! Garrison thinks you are his Mom!
Your chain plates should be on the outside of the boat !
Yes, they should be!!
Oh, this is interesting. I'm watching closely to see how both the engine repair and chain plates go. I'm guessing head gasket on the engine. But what would cause that to happen?? Perhaps some problem with the cooling system and there could have been an over temp during your long run? All guesses on my part but I am interested to know the final verdict. Thanks for sharing.
No we never overheated the engine. The thing has over 4K hours on it so it was pushing time for a rebuild anyway. I just think it’s time! Hell, I’ve put over 1000 miles on that engine since I’ve owned it.
If that oil has anti freeze in it it will destroy bottom end bearings in motor then motor is junk
Sooo,, lots of work to do,,, you have your projects prioritized?
I do, but logistics are based on what I can do monetarily right now and the order of importance is a factor but in the mean time I’m doing what I can and staying busy.

Thanks! Yeah, I’m weighing my options. I can’t afford a rebuild at the moment as mechanics typically start at $175/hr. If I did it myself with some supervision here and there, I would probably take forever, but I’d know the engine when I got done! That’s a massive advantage. It would be good RUclips content also. And cheap! …but yeah, would be really nice to have someone just get it done.

So you didnt rebuild?? WHat did you do for your chainplates?
Can you get at the oil drain plug ? If you use a pan to,catch the oil and drain the oil out the bottle if you have the room , it looks like you can do it from the video??
I dont "believe" there's room, but I could be wrong. I'll certainly confirm.
Oh no , don't spin a bearing 😬
As an experienced car / fighter jet mechanic , I would try and do the head gasket knowing that you need to run a complete overhaul of the engine eventually. The truth about marine diesel engines is that they suck lol 😂. They were only really designed to get you in and out of a marina . People just started using them for long trips. Run it as long as you can’t then scap it and get a larger diesel engine with a combi generator. Regen all day long
Physically larger wouldn’t fit unless there’s something more compact. I do wish I had a generator on the boat!
@ xx
@ it’s more about the cylinder bore size then the actual block and engine stands . Merry Christmas and Happy Yule
As a diesel mechanic not sure if your model has an oil cooler in it. If so that’s easier to pull and pressure test then pulling a head. A pin hole in that cooler will make you oil into milk shake I have also seen one get o oil into the coolant. I am surprised aircraft engines don’t have oil cooler in them also. That would be most mechanics I know would check if one had an oil cooler in it.
The thing about this is money and time . Do as much of the top end as possible without having to remove the block. The heat exchanger has to come off to remove the head . The issue is that engine has been sat . You want peace of mind knowing you’ve done what you can with it in the water . Reseat the valves , new springs , new collets .. very therapeutic. Also learning the rule of 9 with help to adjust the valve clearances . Most mechanics will look at preventing any opportunity to overheat . That means both the heat exchanger and head gasket Xx 🎉
time rebuild ?
Likely! The engine has enough hours on it that I have a feeling it’s as simple as that. It’s just time.
Yummy yummy oil 🛢️
Why didn't you run that engine to warm it up? 😂😂
Because I'm trying to keep this engine if I can!
@@TheSirensLog that was very smart of you. Running that milkshake oil is never a good result.
😍😍❤️😍😍
Hey young lady, nice vest. It suits you & knowing your habits a bit just watching your vids, it's too pretty to get dirty, but hey I leave that to your discretion. Have greatday . Shake oil a bit look for milky appearance. Then you will know.
Baby your engine is too far gone. You're going to have to get it pulled out, cleaned and inspected. Make some flyers for repair. Describe your issues. You need a professional who knows what they're doing. You can't afford to gamble with a Mickey mouse job. Your oil pressure stopped because of that white milky oil. It's in your oil pump, your oil filter every crack and crevice needs to be disassembled and cleaned with no residue left over. And then diagnose your Engine and heat exchanger plus exhaust system properly.
The oil wasn’t milky white either time the oil pressure tanked. The first time the pressure dropped, it literally had all gone out the exhaust. It hadn’t overheated, but we’d just done a 24 hour run so it was hot. Then we put oil in, 20 mins later the oil pressure dropped again but this time there was still oil; and it was still alright, at least in the areas we could see. The milk didn’t show up until two days later. We’d been doing daily maintenance and constant checks to the entire system the whole way. With that said, the engine has well over 4000 hours on it so it wouldn’t be absurd to think it’s a gasket.
Disagree...heat exchanger is the culprit!
I totally disagree with thinking it’s the heat exchanger that unit only has coolant and sea water in it. That unit can’t cross contaminate to the oil. A oil cooler is what I would be looking at if the compression was good in all cylinders. Check into what a heat exchanger is.
@c.a.mcneil7599 my heat exchanger does double duty and has a smaller separate unit for the oil! 😜
@ that’s nice a oil cooler also
@c.a.mcneil7599 TRW mated to j/Deere 💪stronger than 10 acres of garlic! Ha
Rotten decks, shot standing rigging and a worn out engine. Good luck with it, you must really see something in it to want to keep going.
I guess I do. I see an amazing blue water boat in awesome condition for its age. All boats need new rigging throughout the years. That’s not the boats fault. Also, engines have gaskets and they go bad, and all engines eventually need to be rebuilt, not due to anyone’s fault, just the fact that the parts inside don’t last forever. This is how boats are.
Sell it before you put anything else in your mouth
Using design to clean up the crank case is the go. Then make sure you run it with fresh oil warm it up. Then dump that oil. The diesel in oil is hard on your seals. If you have an oil cooler pull it out and pressure test it. That’s a simpler fix.
