Cylinder Head Gasket Troubleshooting On A Sea Doo Jet Ski

[@kennyschopperz]

As a jet ski mechanic myself, I must say, NICE VIDEO! Most people, including myself, don't take the time to film each and every step with detail, or at least 90% of them. This is what sets your video's apart from every one else! Great Job!

I tape a clear water bottle to side off coolant resovior and put overflow tube in it. Go run unit hard. If any coolant is in water bottle the head gasket is blown.

Nice diagnosis and fix. Any theories as to what caused this failure? Did the machine overheat at some point? Factory flaw in the cylinder head surface?

[@3ftDeepChannel]

The head gasket replacement seemed to do the trick, so it appears to have been a bad gasket. We're not sure why it failed, as we don't see it that often, even in older machines.

Currently replacing the head gasket on a 2006 RXT- Pretty great video/ thank you. Never worked on a sea doo before so a few more details in the video would have saved me hours. It would have been extremely beneficial to your viewers to have shown how to turn the engine by hand (17mm on supercharger clockwise) to line up TDC. Location of the chain tensioner bolt/ When to lock the crankshaft. Is it necessary to lock the crankshaft for head gasket? How do I properly clean the surface of the block? Does the camshaft need to be locked when reinstalling? How do you check to make sure timing is correct by hand before starting the motor?

[@3ftDeepChannel]

The crank and cam need to be locked when the cam chain sprocket is installed so the cam timing is correct. The head and block can be cleaned with some 400 grit sand paper wrapped around a hard flat object like a piece of 2x4. Cam timing can be checked by leaving the spark plugs out and rotating the motor by hand to check for any interference and the cam gear marks still line up after a few rotations.

[@ALABAMADAVE]

@@3ftDeepChannel I put #3 at TDC and locked the camshaft only. Used a sharpie to mark the chain/ gear. Never locked the crankshaft but was careful not to pull on the chain when installing the gear. Everything runs great! Thank you for the reply!

Hi. I have a 2007 GTI 155. And there is water in the oil, what could have caused that?

[@tyreebaldwin7598]

Hello you have very informational videos, some people just come to be spoon fed. But you give us what we need thanks! Im having trouble and im wondering if you wouldnt mind a response or two thank you! I have a 06 gti 155. Idk PO.(no history). It needed plugs as they were corroded ski sat for a while, change gas it started fine took it to the lake. About 5 mins on trailer 5 mins 1/4 throttle then limp mode overheating buzzer. Shut down ski started back idled to dock. Took home found oil in coolant, did a blue liquid check stayed blue. Leak down stayed at 10% each cylinder. Has low hours on ski. No bubbles through (cool res). But i do see a few black flakes. Idk what direction to go any help is greatly appreciated and needed thank you!

[@3ftDeepChannel]

There are three ways that problem normally arises: 1. Faulty oil cooler. 2. Faulty head gasket. 3. Faulty seal in water pump. Black flakes usually indicates a bad head gasket, but not always. The overheating warning may actually be a separate problem. That one may just be a bad temperature sensor. I'd check that out. As for the corroded spark plugs, that's not normal. That suggests that water vapor (hopefully not standing water) was in the cylinders, which may also suggest that of the three possible causes of oil mixing it is most likely to be your head gasket. The oil coolers don't fail as regularly, so that would be last on my list. That's where I'd start. Good luck!

[@patrickduran8163]

Okay I believe I have a bad head gasket, however the “gurgling” isn’t coming from my coolant over flow but rather one of my intercooler hoses the water outlet hose to be exact. I would assume that I shouldn’t be hearing and gurgling at all but just wanted to run this by you and see if you have dealt with this kind of scenario. This video has helped a bunch ! I have the little black flakes in my bottle. White chalky residue on my plugs and the gurgling (just in the wrong spot) haha

I am working on a 2013 GTI 130SE and the engine oil leaked into the coolant that made icky mess throughout the entire system, but there is no trace of coolant in the oil. Do you think it's a blown head gasket or a leaking oil cooler? Also, what's a fast way to flush out all that mess from the cooling system?? Thanks for making great videos!

[@3ftDeepChannel]

That's a tough one. We've seen more leaking head gaskets than oil coolers so it's likely the former. But as it's a 2013 model without a supercharger, it's unusual for a head gasket failure. Keep in mind it could also be a coolant pump seal failure. Sorry we can't be more precise as to which one is your issue. After the issue is addressed, I'd drain the coolant the usual way, fill it with coolant system cleaning solution, follow the instructions and drain again. Repeat until the coolant is clean. Good luck and thanks for the kind words!

I don't know how much you can remove before running into clearance problems I think there are some recessed spots in the head surface as long as these are still visible after resurfacing the head is good, can't remember where I read that. Every time I have had a head resurfaced I have asked the machine shop to take off the minimum needed to achieve a flat surface I always use an oem head gasket with new head bolts, if you want to go one step better get some ARP head studs instead of the oem head bolts. If a thicker head gasket would make you feel better Cometic make them in different sizes.

So I'm thinking about pulling it back apart, machining the head and new gasket. Maybe I got the wrong head gasket? Thoughts on where failures can be made while reassembly?

@@3ftDeepChannel So I think the gasket maker I used sucked for mating the upper and lower engine halves together and that's where the oil leak was. I mistimed the engine not using the crankshaft and camshaft pins, I don't know why. Also, I put the pistons in 180 degrees off with the arrows facing the intake side. So the first time I cranked the engine, it bent all 6 exhaust valves and broke the rocker arms. I'm an idiot and can't believe I did that.

Boy, that’s a tough one to answer over the Internet. There are certain things that need to be replaced when you pull your engine apart, including stretch bolts and gaskets.

Well, the good news is that if it is only the head gasket then it will be a fraction of my estimated cost.

There was also oil splatter in the hull on the port side. The white smoke smelled more like burning oil than like steam from over heating coolant. The oil splatter in the hull and the oil on the dip stick looks clean, not milky. Could a failed head gasket cause these symptoms, or something else?

[@3ftDeepChannel]

It sounds like something failed catastrophically. Not sure about a head gasket though, as the “oil” splatter is unusual. I’m wondering if it’s a carbon seal failure.

[@3ftDeepChannel]

That is the most likely culprit. The coolant appears to have gone into the oil. It could also enter the oil through a failure in the oil cooler, or the water pump. But it is extremely rare to see any of these failures in such a newer machine. Good luck.

[@tinokamung846]

@@3ftDeepChannel Thank you for replying! What would be symptoms of coolant in the oil? There's were no warning lights or errors codes on the computer.

I did have an issue where rocks got stuck in the impeller and threw off the engine timing but that was fixed and the machine ran for about 10 hours with no issues. It was only the other day when it ran out of gas and then steam was coming out of the exhaust that the mechanic noticed the coolant problem

[@3ftDeepChannel]

A milky or milkshake appearance of the oil is a symptom of coolant intrusion. A code is not always thrown when this happens. Age normally causes the head gasket to degrade. Engine damage could also cause the leak. It is possible that you have a defective head gasket, but that is very rare. Is it possible that anyone took apart your engine at some point, and did not torque the head bolts down properly? That could also cause the issue.

Another mechanic suggested that the milky oil is from water entering the exhaust while towing and that the coolant loss is a result of draining and refilling the reservoir to do engine work

[@3ftDeepChannel]

Well, that would explain it. Those head bolts are very important part of your engine. If new ones are not used when the engine is taken apart and they are not torqued properly, then this problem can result.

I just bought a 2013 Seadoo RXTX 260. While i was test driving it, it appeared to have surging issue. There were parts of the lake that were shallow and I hit a sand bar. The owner swore that there was nothing wrong with it. Thinking that the shallow lake caused the surging issue, i bought it. I took it out for the first time today at a well known lake. Surging issue persisted. Eventually, it got worse where the engine started shaking and it would not go past 20mph. I went home and pulled the spark plugs. The 2nd cylinder has oil in it and the oil now has water. It is creamy coffee looking. The reservoir did not have any oil residue and was halfway between low and max, so I'm not sure if the water came from the antifreeze. Is this a head gasket problem?

Hello Kevin, Sorry to hear of your problem; there are a number of possible issues, including the head gasket. Most likely there's a leak in your intercooler and it's taking in water.

@@3ftDeepChannel I think I found the issue. The ski didnt come with drain plugs. So I bought and installed them. I also plugged the flush port since I've seen a gtx model with them. Based on my research, they are supposed to be left open. Therefore, the water have no where to drain and got into the engine. I had it on for 15-20 mins. Will that cause any damage? Besides flushing the oil, what else would need to be done? Cylinder 2 have water in it. How do I get it out? I removed the spark plugs and cranked it but it still is wet.

[@3ftDeepChannel]

You’ll need to get the water out of your engine immediately to minimize the damage. It will start corroding your engine immediately, so the quicker you get it out, the better. Most people figure it starts causing serious damage after a few days, especially if it is salt water. As long as you don’t hydrolock your cylinder, you should be okay. They process is to run the engine in “drown mode” with your spark plugs out to shoot out any water. It will clear most of the water out in 10 seconds or so. The rest of it will evacuate when it’s running. You should also change your oil at least 2 times and until there is no milkiness in the oil. If you can get hold of a Service Manual for your machine, it will have the proper process for getting the oil out, but in a pinch the suggestions we just gave should work, but do it right away. Good luck!

Also, I notice there is water droplets in the air intake hose of supercharger (not intercooler). Engine will barely rev to 4000 rpm out of water.

[@3ftDeepChannel]

Thanks for the kind words. We suggest getting the cheapest oil you can find (that’s suitable for the machine) and flushing ASAP as many times as required until it’s no longer milky. If the milk keeps forming, then it’s probably your intercooler. That could explain your low RPMs. When you no longer see water in the oil, change it one last time with the proper oil. I know it’s costly, but you’ve got to get the water out of the oil.

Do you see any oil or dark flakes in the coolant reservoir?

Very informative brother thanks 😊

Video about fixing problems on yamaha jetskis ?

[@3ftDeepChannel]

Only one series, after the cylinder head cracked. Sorry, but we just work on our own machines (Sea-Doos), or machines that friends ask us to fix.

[@rennanazevedo3437]

@@3ftDeepChannel Thanks. Can you tell me which brand has the least problems with entry jetskis? Yamaha or Sea doo (2008 - 2015)

[@3ftDeepChannel]

For entry-level machines, they are all very good. I would stay away from supercharged or intercooled models, though if you want to minimize problems. If I was looking for my first ski, I would stick with Sea-Doo. Good luck.

[@danielkerekes3588]

Hi, thanks so much for all your videos, they are awesome. I just bought a 2008 RXP X 255 last week (250 hours on engine). I've only taken it out on the water a couple of times, but it was sluggish in acceleration and had a low top speed (around 40 mph). I found the same problem as the other commenter, Tino - coolant reservoir is empty and oil is overfull and milky. Based on your responses it sounds like it could be a head gasket issue, hopefully it doesn't break the bank. Thanks for explaining all of these problems.

[@3ftDeepChannel]

My first guess would be head gasket. Although it could also be a few other things. Thanks for the kind words, Daniel and good luck.

[@danielkerekes3588]

@@3ftDeepChannel Thanks for your reply! I just spoke with the local jet ski repair shop and they said it also might be the oil cooler, because it is pretty uncommon to see ALL of the coolant leak into the oil and really overfill the oil with just a head gasket issue. But they don't have availability to do diagnostics for a while. Does that also sound reasonable to you? Do you have a video on how to remove the oil cooler and/or leak test it?

[@3ftDeepChannel]

Yes, that would’ve been our second choice. The oil cooler is very easy to remove. There are just a few bolts holding it on. No video on removing it specifically, but it is seen in the one where we take apart the GTI SE 130 ski with 900 hours on it. Good luck.

[@danielkerekes3588]

I'm having fuel problems I rebuilt the motor and it is not taking the gas like you should could you give me any tips what it could be or how could I get up with you to check it out check engine light is on also I just need some help

[@3ftDeepChannel]

You may have damaged a fuel injector when you removed the rail. Where are you located?

[@timdial372]

I've cleaned injectors with power same to be spraying and clicking just fine as normal as any other tips that might be the problem

[@3ftDeepChannel]

Are you absolutely sure your spark plugs are OK? I don’t see any other way your engine rebuild would be creating an issue. Please check for codes and let me know what you find. If the engine light is on, there must be a code. Your owners manual should be able to help you look for codes.

[@timdial372]

I'm going to change the plugs and see if that makes a difference.. the ski has been sitting about 4 years and don't have any code on it... I carried it to the local dealer the only thing he said that IBR brake system was causing the engine light to come on but it has a solid beep.. before starting what could that be?

[@3ftDeepChannel]

That long beep is just a generic trouble sound. It may also have a problem reading the key. But that shouldn’t result from doing work on your engine. Anyway you could video the issues and send it to our email listed on her channel? That would help. If you do, Make sure you film the gauge cluster when you start it up.

[@DevonSpittleREAL]

excellent!

[@3ftDeepChannel]

Thanks!

[@IHadToMakeThisAccount]

What good is machining the head flat if you don’t do the block, in the Subaru world that can buy you maybe 5000 miles best case scenario.

[@3ftDeepChannel]

We only do what's necessary, to minimize expense. Thanks for your comment.

[@justinanderson181]

Previous owner of my Impreza tried to cheap out on not resurfacing heads after the sohc ej25 decided it wanted to introduce oil and coolant to each other. Spent 2 days tearing the engine out and buying all the new parts like valve gaskets and new head bolts and 7000 miles later he has oil coolant soup on his dipstick. Second time around he got OEM MLS head gaskets from a WRX STI and put it in along with making sure to get a head job done at a local shop. Lesson learned was do it right the first time

[@3ftDeepChannel]

Thanks for the tip, Justin.

Good thing this isn't a Subaru 🤣

Very nic sir .. sir i am surching job for this ... .. my qulifiaction is diploma in mechanical and .. i have working experience in bike show room ..

[@3ftDeepChannel]

We are not a dealership that employs people, but I’m sure if you went to your local dealership you might find some work in the shop. Good luck!

[@DennisSwanson517]

Why not use arp head studs it’s not much more expensive than the stretch bolts and they are reusable.

[@3ftDeepChannel]

Those are fine. We’ve used them before. We usually like OEM stuff, whenever we can afford it.

[@DennisSwanson517]

Can I ask why you prefer the oem stuff. I recently rebuilt my 185 and used arp for everything and I have right around 15 hrs on it with no issues

[@3ftDeepChannel]

OEM is always good because it was designed specifically for their machines. ARP are at least as good, though. I’m sure you’ll have many great hours on it.

[@DennisSwanson517]

Well I want to personally thank you because of your videos on the supercharger failure I was able to put it back together and it run good. And I did put super tech valves in the exhaust I left the intake ones. Thanks again for all the help

you’re welcome. Glad to hear you’re doing it on your own and saving money!

Hi there

[@3ftDeepChannel]

Hello!

[@Bmxjoe26]

90% chance that gasket was fine. The oil from the tube can cause intermittent misfire under loads. That will cause surging. 10 minutes some new tunes and a water test could have saved some time and money.

[@3ftDeepChannel]

What tube are you referring to? The spark plug pipe?

[@victorstephenson4591]

How do explain the gurgling in the cooling system?

[@3ftDeepChannel]

The gurgling comes from air in the cooling system.

[@Bmxjoe26]

Yes we the spark plug tubes are a terrible design and are a common culprit for oil leaks onto the plug/coil causing intermittent misfire or loss of RPM they have been redesigned and and still suck. @@3ftDeepChannel

[@andrewmccafferty1126]

I feel like a new gasket was in order after seeing all that crud in the coolant reservoir
