G'day Alex, I experienced a very similar issue when replacing my cam gears and gaskets, along with belts, and several other seals or gaskets, on the front end of my Eclipse. When you're replacing as many seals or gaskets as you did, it's obviously, going to directly effect the oil pressure. As the pressure increases, the original graphite, factory head gasket (very btittle), can no longer support the increased pressure...and it fails. The head gasket was probably ready to crack, before you even began replacing cam gears, timing belt, etc...Cheers from Western Australia 🇦🇺.

[@legros731]

Leaking oil seal doesn't affect oil pressure But it sure does affect the crankcase pressure inside the engine all the extra pressure was relieved by the leaky cam seal now with brand new seal there nowhere for the pressure to release so it found the weakest link the head gasket at one of the 4 corner oil return hole to the pan Two possibilities here the engine is worn-out lot of blow-by or the pcv system is not working correctly

[@fiercenet]

my thought too... with all those leaks fixed the oil took the new path of least resistance.

[@rangeraficionado87]

The oil filter could also be faulty, no? He also could have gotten a chunk of RTV blown into a passage somewhere with all the cleaner and compressed air he was blowing around..

[@legros731]

@@rangeraficionado87 not possible the only access to the oil gallery is the oil pickup tube It go from pick up tube to oil pump to oil filter oil filter have a bypass in case of excessive pressure to prevent the filter from blowing up It's probably a crankcase pressure problem the pressure was relieved by the leaky cam seal now the pressure got nowhere to go so it found the next weakest link in this case the head gasket and in the corner is the oil return from the head to the pan and the gasket is pretty thin at this place And it's a common place for head gasket to leak as well

[@Mtlmshr]

That my friend makes perfect sense to me and I would agree with your line of thought!

[@stevecbr929]

Welcome to the wonderful world of DSM's my friend. I have a 95 Eagle Talon TSi (same AWD turbo as Eclipse, different bumpers). I honestly can't tell you how many times I've had mine apart, currently on 3rd & hopefully final engine setup - built 6 bolt block with 2g head. You're doing great, pretty sure your head gasket was just tired & sitting around mostly for better part of a year it was just it's time.. couple of suggestions that come from almost 20 years with this car: get rid of that crank sensor! DSM link will let you run a 1g CAS - simple swap that let's you drop that crank sensor/trigger wheel & your 2g cam sensor & pick up inside the cam gear. The "hall effect" 1g cam sensor will do both & it's literally checking a box on your DSM link software & splicing a couple of wires (or they sell a harness thru DSM link I beleive). Great job on your timing belt - again, suggestions based on horrific 1st hand experience: the vibration isn't that bad - you can always jump in your CL65 (I've had a 04 CL55 for about 2 years & 3 ABC line explosions!). Drop the balance shaft so you can get rid of that belt. If/when that belt should break, it will destroy all that is close to it - crank sensor, your timing belt & parts that keep it in time, hello interference engine, I didn't like those valves anyway! Also, I've never had a Gates racing timing belt (the blue one) fail, fray or break ever & is worth the extra $ in my opinion. Sorry about the novel, your doing great - don't let the DSM issues bum you out, it pays off once you get it going again until something else let's go until ultimately, you too will end up with a built 6-bolt! Good luck man - keep up the great vids/builds!

This video series brings up so many memories and emotions. DSM was my life years ago. It was my first project car. I turbocharged a non-turbo 4g63, smoked all my friends and blew up the tranny. Went to the junkyard and picked up a turbo tranny for $75 and was back in business. Back then parts were cheap and it was so much fun!

Okay, I just finished binge watching your entire series on this GSX-to say it has been massively interesting would be an understatement! Thanks for all the hard work you put into these very educational videos. Would I ever do something like this? Absolutely not! But I could hand you a wrench. 😂 Thanks again!

[@blackbuick1987]

Maybe fixing all of the other leaks like the cam seals and oil filter housing gaskets caused the engine to make enough oil pressure to push out of the head gasket? You also mentioned the oil pump wasn’t aligned before so again maybe after aligning it bumped the pressure up to start exposing leaks. Think of it as a blessing because once you put it on the dyno that head gasket was probably going to blow anyway if it is indeed original. Possibly saved you from catastrophic failure later on.

[@Cougracer67]

There is not any pressurized oil behind those seals, so changing them has absolute zero effect on oil pressure!

[@m4rvinmartian]

This is the answer.

Alex, I've only seen one head gasket leak oil. That was the M104 on our 1993 300E 2.8 engine. Of course, it was already over 150k miles and was original and was just a very tiny leak. So, I left it alone. Didn't want to tackle it. It never showed up by losing oil on the dipstick adn never made a mess. Just normal stuff fro that engine, I believe. Recently, on the M276 engine in our `13 C300 4Matic, I had a bit of oil leaking from the camshaft position sensors and solenoids, so I replance them all, including adding the pigtails onto the wires, so the oil wouldn't wick into the ECU. The wires were dry, but the pigtails were cheap insurance, so why not... eh? I had one which was impossible to replace unless I popped up the intake, so I took it to my shop and they did that one. [They had to pop it all off with new gaskets and peeked inside the intakes and there was no carbon buildup. At 120k miles on a direct-injection motor... WOO HOO!!! A big THANKS to M-B for that design. Impressive. Of course, I also use Shell premium, Liqui-Moly oil every 5k miles and drive it hard when getting on the I-states. I get 30-32mpg on the road at 75mph, and it runs great for a car with a retuned E-class M276 motor. Oh, how I'd love to get that ECU tuned to its full potential. The car does 0-60 in under 7 secs. Handles better than our 98 SLK230, and all on original stuff. Of course, I'm going to install new Akebono pads on (they've lasted over 60k miles on the Zimmerman discs) & check it all out before a big road trip in August.]

[@yokai8896]

New to the channel and caught up on this series since I have a 98 GSX, you make it look so easy, can definitely tell you've been building cars for a while. Really smooth content. Researching and ordering parts in a good sequence is really hard imo and you've done everything pretty much the same way that I would. Awesome tip on the muffin trays You should inspect the harmonic balancer closer because the OEM ones separate at 100k, it must have been replaced already. Fluidampr is a good upgrade, they can't fall apart and smooth out the engine some like when starting from a stop and rev matches Be a lot more careful with the valve cover they're known to crack, as well as the rear diff covers. Watch the tightening sequence and don't over tighten etc just treat them like they're gonna break T6R's look great, I still think red calipers would be cool but the silver is clean too

[@resilva2]

Most of the other comments pretty much pinpoint it,.. but at @ 10:44 my theory is that all the vibrating and cleaning got into the graphite gasket and loosened up what was already a very slight seepage leak. And then perhaps by putting the oil pump back in the correct timing and fixing the oil coolant filter gaskets, it pulsated the oil at a different pressure or different time and the head gasket corner was no longer able to deal with it. The weakest link in oil gaskets presented itself.. especially after probably accidentally getting messed with and soaking up a bunch of degreaser. I've worked on DSMs for the last 30 years and they're probably just as picky or picker then any high-performance race engine. The tolerances are pretty tight to make sure that car runs properly.

[@legros731]

I would say you are wrong It's a crankcase pressure issue the blown cam seal allowed the crankcase pressure to escape Now that it got nowhere to escape it found the next weakest link the head gasket Two possibilities here excessive blow-by or pvc system malfunction For it to happen in a such sort notice would point towards a crankcase pressure problem Somebody I know used the brake booster hose for the vent on the valve cover (engine was a b18b Honda) The hose got a check valve inside so the booster keep is vacuum so it was effectively just blocking the vent in the valve cover It took like 5 second of run time to pop both can seal right out and made a massive oil spill

[@poot111111]

I don't think it has anything to do with the timing job. I would guess it has more to do with the car & gaskets sitting for a very long time and now it is being brought back to life. Often gaskets will shrivel up when they do not see oil and pressure from typical operation. I'm sure you will have it fixed in no time Alex, you always do!

[@feron450]

That’s exactly what I was thinking while 240k miles is a lot it’s not for the year the car is. That thing probably sat for a good portion of its life. And now with bigger turbo and more power the gasket just couldn’t take driving again. Very odd that it was the oil side that went though

[@alk5749]

I agree with that assessment, I’ve had a car blow its head gasket after sitting for a couple of months. Older car with high mileage.

[@thagerdorn2009]

You can't let a car sit. Hearing him say he never drives it means he needs to sell it to someone who will drive it. I'm so sick of seeing these people with all these damn cars and never drive them. Plus it's a 4G Mitsubishi engine...they are notoriously unreliable. Close and long time friend of mine was huge into DSM for many many years so I know all about them. Head gaskets are very common if they sit.

[@jonsmith6496]

Has something to do with all his cleaning too I’m guessing.

[@turbo_brian]

The oil drain leaking is super common. Most likely the flanges are not warped. What a lot of people don't realize is that the washers on the bolts are non reusable gaskets. Replace the washers with new ones and use a new gasket and put a super small dab of rtv on the threads of the bolts. Then it shouldn't leak.

[@boostddsm]

Came here to say this exact thing. This is 100% why the oil drain keeps leaking. You could fix it by installing an AN adapter to the oil pan and turbo, and use an AN oil return line so you never have the mess with the drain line fittings anymore.

[@andrewthomason3857]

⁠@@boostddsmBack when I had my 90 Talon, I always thought one of the DSM parts vendors should have marketed something like that. You had to take that stupid pipe off a lot to work on the engine, and it was always hard to get a leak-free connection to the oil pan when it went back on.

[@DarkRider2k3]

I did all of this on my Eclipse back in 2021 when I replaced my worn/overheating engine and as crazy as it sounds my previous engine wasn't vibrating, but the belt for the harmonic balancer was ripped off due to an oil leak in the same spots you had. The engine wasn't any good though because it had overheated on the previous owner (a friend of mine) and when I took it all apart the block was pitted and damaged and it was cheaper to get a donor engine then to try and completely redo the old ~125k miles engine. But same oil leaks and this is bringing back memories of when I first attempted to look at the original motor in it!

[@End3r_Wiggin]

The bosses on the top of the exhaust manifold are there to install pyrometers to plug into a stand-alone ECU. Using those, you get more finite control over each cylinders' A/F ratio when tuning, instead of only relying on a downstream WB O2 sensor that's reading the total.

[@disgruntledegghead6923]

I'm thinking the head gasket simply got jealous of all the work you did to the front. It was just it's time, and it's way better that you found it before making a mess on the dyno floor...

[@aymenhasan]

Could it be that the gasket was on the verge of going, but when you torched the left hand side 14mm header bolt with the large MAP gas flame, the flame was catching the edge of the gasket and was just enough heat it quite quickly and intensly and cause it to blow right at that corner? Maybe there's an oil gallery quite close to that corner?

[@ospinal921]

Love the DSm content Alex. Great Video, and um welcome to the DSM world lol. Glad you found the leak before the Dyno. I agree with everyone else here, maybe by fixing all the leaks and the correct alignment of the oil pump, it now made more pressure, also I bet that high iddle was because the turbo compressor side wasn't hooked up all the way. All said and done, new head gasket, and a new- street tune before dyno. 🔥

[@konstantinoschristodoulou355]

It happened to me, by fixing many leaking small points like: changing oil pan gasket, oil cooling gasket, and crankshaft gaskets...it started leaking from an engine oil gallery plug, which was a little bit defect but never leaked before. I think by fixing everything (gaskets and leaking points) changes the oil pressure, and oil finds a way out on a weak spot...I guess fixing all gaskets and o-rings will be the answer on an old car...we all learned that in a bad way! *i personally hate moments like this but I'm so happy that you will show that in a new video, love and peace bro!!

Sealing the oil leaks can make weak points in other areas leak. The car came from a dry climate and it has lots of miles so would not be surprised weak points could start leaking with the higher fluid pressures. It like when you use regular oil then go synthetic on a high mileage vehicle and it starts leaking because the synthetic cleaned everything.

[@Cougracer67]

No, changing one seal has absolutely no effect on the other seals. There is no pressurized oil behind those so fluid pressures are not changed!

Still my 06 Mazda rx8 is really what replaced this car and the twin turbo rotary spitting fire and the handling just killed my love for dsms. What I love about you Alex is we have the same taste in cars. I to have a supercharged van but mine isn't a cargo van it's a explorer conversion out of mishewaka Indiana. You should look into finding a early 2000s Ford exonoline conversion van and drop a big supercharged Benz or audi v8 in it. That's my future plan as ls swaps are so boring and I love the 12 and newer Benz biturbo v8s. I have a 2014 Benz cls63 that has this engine built by the only female at amg at the time and it's such a reliable mean car.

Yes its Legit Saturday!!!!

[@sibusisoshongwe]

Sounds nice, legit street Saturdays

[@kevshaw2020]

The dsm gods have cursed you. Don't worry this is how it works. Soon you will start chasing random wiring issues, drive train issues and lots of fun dsm "quality" fails lol I thoroughly enjoyed this video and all of your stuff dude ! Keep it up !

[@jeffmac3071]

Alex, the helpful hints (3/8" drill bit for timing) was great.

[@williamkelley7654]

I think you hit the nail on the head when you said you should have pulled the motor to work on it. Honestly, with that mileage, that oil leak may have actually saved that engine. Good luck! Can't wait for the repair/tune videos to come.

[@sinoverlord409]

I'm developing a Alex sense as to when precisely he will drop a video. I was only one minute off.

[@mcskull88]

When you where using the torch on the manifold studs you Probbaly set the outside of the head gasket on fire

[@rubbishcar]

Super enjoyable video. Thanks!

[@markblunsum6164]

You make working on cars look so easy, also really informative and entertaining! 😊

[@joelwachter7845]

The plug on the power steering pump is so the engine idles higher when you turn the wheel so the steering doesn't get heavy. Lots of mazdas have that as well. When you turn the wheel you will hear the engine idle up.

[@alexandrecouture2462]

Cool! I didn't know it was a thing.

[@mikeysbago-meat7967]

Yeah lots of Japanese cars have done this especially in the 80s and 90s some had vacuum switches others were electrical switches. My 85 Dodge D50 pickup which was a Mitsubishi import had a vacuum switch.

[@wlol9263]

I work on huge turbochargers. In my experience old graphite is a is a strange puppy sometimes. What I’m thinking is that the vibration that you were having beforehand was slowly but surely braking up and when you resealed the lube oil system the slightly higher pressure finally blew it out. You did also say it has 200K+ miles on it probably OE and had never been changed. Graphite gets really hard and brittle with time and heat cycling. I wouldn’t worry too much. Definitely go with a newer style head gasket with better material if you plan on throwing some crazy boost at it to avoid any issues going forward. Love the content bud. I can’t wait for the next episode!

[@Fred-dd6uw]

Welcome to the world of Mitsubishi. Since you're going to have the timing apart, you may want to change the seals on the oil pump shaft and the balance shaft. They will leak just as bad as the cam/crank seals. Also, when aligning the timing mark on the balance shaft gear, you want to spin the gear until it kinda lands on the timing mark. If you give the shaft a spin, you will see that it wants to land at one of three spots. One of those will be at the timing mark. If you don't get this correct, the balance shafts will be out of time and engine will feel like it has a bunch of angry bumble bees inside of it. Hope this help. I enjoy watching your videos.

[@garylucas2126]

What a bummer, but at least you can build the engine the Legit way! I have been mentally preparing myself to replace crank seals and more on an equally leaky Celica but this video has shaken my confidence. 😢

[@TheBananaMan4321]

my day has been made now that you uploaded

[@nosetdirection]

I quit chasing speed, has made my life a lot easier.

[@john-vy1ml]

Haha. So true. Now I just chase good handling and braking. 👍

[@GldVWisRR]

speed with cars. I ride motorcycles now. Cheaper.

[@jochenstacker7448]

​@@GldVWisRR ride safe dude, speed on bikes is just so much more painful when it goes wrong. 🙂👍🖖

[@Jackofheart1]

At least people can see that anyone can have issues even though you weren’t touching that other part ! When some mechanic fix an issue anything can happen. It’s weird but it happened to me working on someone’s car! Not the head gasket but transmission pan gasket! Lol 😂 customer didn’t care and wanted me to fix it without having to pay for it! Sometimes you just got to swallow the pill and continue doing your best no matter what others say or think! Good luck and thanks for entertaining us the way you do it😊!!!! ❤❤❤

[@davidgore3292]

Great Video!! All The Best Brother....

[@LeaveMeAlone1978]

You caught the corner of the head gasket with the drill brush while cleaning and probably bopped it just enough to break the seal. Looks like the corner of it sticks out so maybe something super weird happened when you cleaned it??

[@ryandoyle4344]

Sometimes the grime keeps it sealed up. (master cylinder)

[@LeaveMeAlone1978]

@@ryandoyle4344 lol true. It was a slower leak before because it was so gummed up. Makes sense. Either way it’s an easy fix on this car. Very easy.

[@david1o819]

I get scared to clean my master seals every time!😅

Dude, Nice work 👌. I'm impressed 👏.

[@SteveTheBeardedWonder]

I really love this channel and Alex with his personality. Been a great distraction as I'm going through some hard times. Keep up the awesome work. I love dsm cars

[@SteveTheBeardedWonder]

Sucks to see the head gasket. We know you'll fix it and make it better. That's extremely strange. Sorry to see that.

[@mrld3005]

Wow did not know Ben Shapiro was also a mechanic! is there anything this man can not do!!

[@lka1988]

26:50 I keep expecting a jump cut to you chucking the water pump into a trash bin... I watch too much "I Do Cars"😂

[@darrelhandgraaf7708]

Good video. Sorry about the head gasket leak.

[@totallybonkers]

Another exciting and excellent episode! and the harp joke had me laughing 😂

[@DQ81]

I'm of the same school of thought. Ypu fixed 3 major leaks. Hogher oil oressure found it's weakest point. Good catch and have fun doing that head. At least its an accessable 4 banger!

[@End3r_Wiggin]

Recommendation: One of the mods that gave the best tactile improvement, was replacing the shifter with a Fidanza short shifter with counterweighted knob, and swapping out solid metal bushings for both the shifter mounting plate under the console, and solid bushings on the transmission where the cables connect. A massive improvement.

[@howeybros]

Great episode Alex!

[@scout1633]

Alex - so sorry to watch this set back . But I know you will overcome and bring this engine back to life . Wrench away !!

[@GuapBoiTV]

@legitstreetcars you got me sold on the tuxmats! About to get a set for the Escalade.

[@glenkelly998]

Another great video At least all the stuffs going to come off easy I did feel your pain 😞 With all what you've done to improve the power of this engine a head gasket etc makes perfect sense 👌

[@jivemastert]

Your previous DSM videos made me miss mine and remember it fondly. This video reminds me of why I sold it.

[@paulvaz5846]

Cheers Alex and Max!

[@thlee5902]

AMG did tune some Mitsubishi cars back in the days. Your AMG hose is legit!

[@michaelreno4136]

I was definitely not expecting that to happen. But anyways I look forward to watching your upload every week.

[@davidotoole-nu4ig]

As always, terrific work! Unfortunately, I believe your cleanliness may have led to the oil leak. Either the head gasket was ready to fail, or had failed previously and been hastily repaired. The undoing was likely the copious application of engine degreaser and forced air during the cleaning process. What should have been a stable corner was likely a failure waiting to happen. Fortunately, an issue like this, which would derail most others, seems par for the course for you. The more work it needs, the better story there will be to tell! Keep it up Alex - you're definitely the real deal!

[@johnhicks913]

A gift from across the pond !!

[@octaviocortes6684]

Great video!!!!!

[@RayRyan1123]

These videos have made me miss my 95 gst. It had a 2.3 stroker build even had those wheels on it but they bronze.

[@JonUF02]

Just like I did my front brakes on my ML63 recently. When I dropped it down and started it up it started puking coolant. Now I'm deep into replacing all the brittle turbo coolant lines on my M157, long with a bunch of while you're in there and a couple of upgrades.
