The oil in the cooling system is probably in the process of destroying all of the rubber hoses in the system. They swell up, get soft, and burst.

This would make a great commercial for Shout® Stain Remover. Oil in your cooling system? SHOUT IT OUT !

After seeing the hoses collapse under vacuum, I knew you were going to have problems with them.

Oil in the coolant made the rubber Y hose soft and all the other rubber hoses. Bite the bullet and replace the hoses.

@ 16:43 - Noooo Randy. PLEASE. If there is one car you do not 'have fun with some mods' its a Porsche 911. I will keep repeating it "Originality is everything". Keep it original and you will find a buyer looking to pay Porsche money and you will make a profit. Mod it and you lose the genuine Porsche buyers and you are in Lottery Land. It is a lovely car though Randy. Well done finding it and restoring it to good health. God drives Porsche and he will bless you! ...lol If the oil does return I would be looking at the oil / coolant intercooler not a damaged head. It runs too well for that.

Meaby that small hose was bit bad and when you "sucked" it, it bursted... Hmm that vacuum suck might really bust old hoses..

Randy,,,those hoses are splitting open because they are old...but when you do the vacuum it spreads the chords inside and hence splits them open. We stopped using this airlift machine in our shop for this exact reason.

Cant wait to see the update and outcome on the Porsche! Thanks for the great content. Cheers from Australia.

Love the channel gives me something good to watch! Keep it coming Randy

Love the working videos. Thank you for doing more videos like this!!! I enjoy them all and your work. Doing great job Ramdy!! Keep it up!!!

Great update. Fun watching your channel...great content

Great video, thank you for the upload greatly appreciate it. I plan to get my hands on a Porsche one day.

Randy, this is incredible content. Can't wait till the next video!

Good stuff...your commentary is spot on and so is your video. I can actually see what you are talking about and your camera is more steady than a number of other channels (shaky camera work is the bane of any KZfaq viewing experience). Too bad about the other hoses breaking, but, at least you weren't in the middle of the freeway when it happened. Just sub'd and thumbs up!!

My 01 Boxster S has the oil in coolant. Fantastic to watch your work on this car. Yes, I had to keep replacing hoses till I sold the car. Love Porsches.

I love these videos. Im looking at a 986 boxster. Cant wait to see the next video.

Awesome work. The problems you're running into is due to the previous owners lack of maintenance , nothing more and not the cars fault. Kind glad someone who loves tinkering has this car now and working on it.

I admire your persistence. Well done sir.

Just found this channel, fascinating stuff...enjoying the journey, love it!

Randy , when you use the vacuum generate with the old hoses on that Porsche , they will crack , it is normal .

Thanks great video, informative I've never seen before. Great tip on cleaning out coolant system.

Just found your channel, love the content.

I certainly hope you scored big on this Porsche. Really enjoying the troubleshooting aspect of this one.

Just replace all coolant system hoses. It will be less of a headache, especially now that you know the block should be mostly clear of oil in the coolant passages.

wow love the old school atari / commodore pet sitting on u bench at end of vid...nice

Hi Randy. I would replace all the rubber coolant hoses. Buy off e bay. If oil still gets into cooling system, its probably a crack in the oil cooler. Rev.

one round of flushing is all you really needed to get almost all the erl out. sure you may have some residual erl left, but, thats a good thing...the coolant would still do its job, the small amount of erl in the system shouldnt affect the rubber hoses swelling hardly at all if any....and you would have extra lubrication in the system for the water pump and heater valves for longer life.

Randy you're a 5 stars man, amazing content, thank you for sharing your knowledge.

I love all your content Randy. Love all the cars and CoPart walk-arounds. Stay cool in Oklahoma

Any content is great content!! Keep it coming!!

Love the video I would really like to see more of this car.

Hello Randy. Get the 2 new Porsche hoses and hope the best of luck for you.I can not wait to see the Porsche running down on the freeway.Keep up the good work.Greeting from Venezuela!!!!!!

just watched this playlist, as soon as you put your finger in the coolant tank i said somebody put oil in the wrong spot as it was pure clean oil, the more you looked the more to me it seemed somebody did an oil change and filled up the coolant tank, it was FULL lol they proceeded to start the car which killed the original engine, that engine was changed as we know now with a brand new 1 but they did not clean out the coolant tank and as the system expanded and contracted some of the oil went through the system which is why the oil level never dropped and coolant never went typical milkshake colour just an dirty water colour, My wife whom is petrified of cars and car crashes also enjoys your vids especially the copart walk arounds, so its a win for me, greetz from Western Australia.

Blue 996 Convertible looks sweet even if you did spend the top $j still say it’s worth it with bearings corrected and all other problems fixed you re good to go. Beautiful looker - convertible no less. My thinking is because of the Shout , the soap bubbles created more gas pressure thereby blowing any weak link ( hose) thus your leak on a minor hose. Tanks for the review .

nice work solid vid

Love the Porsche content. that is the reason I subscribed.

Great video enjoyed watching keep up the great

Can’t wait for the next instalment. Good luck.

Replacing coolant on a MGTF135 mid engine car I removed the radiator (at the front), flushed it many times and then did lots of heat cycles with clean water. Surprised at how long radiator took to get hot. Enjoyed doing job right. Wasn't any reason to do flush other than it hadn't been changed for a while (a long while).

It swelled from the oil contamination. It will eventually kill all the hoses.

Dawn dish soap works well. As does cascade powder premixed with warm water mixed in. I have used the combination a couple times to clean up after a blown head gasket. Followed by a lot of clean water flush then a flush of water and coolant flush. Then flush with distilled. Then filled with coolant. I never saw any trace of oil in the coolant system again..

Randy before considering the head have you considered the engine oil cooler, you could remove it and have it pressure tested, if it was it could save disturbing the head,

Great video. Go ahead and replace all the rubber hoses and plastic hoses you can get to in the engine bay. It will help you out and eliminate all your troubles. VAG cars tend to have crazy hoses to go out. It's always the weird hoses too.

Great job!! I believe you scored 👍🏻. And I think you just need to have all the rubber hoses replaced the oil will eat the rubber hoses and soften them.

Although a Porsche is not on my horizon, your experience was fascinating enough to stay with the story through the end. Nice camera work, despite the high- and low-light conditions, and very much enjoyed your narrative of discovery. Most important, you helped dispel the myth, once and for all, that a Porsche is somehow immune to all the annoyances of a regular commuter car-- broken hoses, poor service at the hands of "somebody", and discovery of really bad materials design (as though the OEM wanted the part to fail). Thanks for the ride-- notice the superior yes-to-no ratio.

Randy this is a great exercise in patience! Hope it pays off, but does make for interesting content. Can't wait to see the outcome.....

Bob Moore’s never owned this vehicle and yet he’s profited the most off it lol.

Richard Simmons workout going on for all of the rubber parts in the cooling system! Maybe stuff a few Big Macs into the radiator to harden up the arteries? Just pulling your chain, love your content Randy, best of luck to your repair efforts!

Showed my friend the last 911 vid as he works at a porsche dearlships and works on 911's all day long, he said look at the hoses if NO fix its internal and you need to bring it in for a check over? Its the best I could do for you, I love your 911 and you will get a great price for it👍

Neat cooling flush idea!! Looks like it works very well!! Congrats!!

Due to the oil mixed with the coolant the temperature fluctuates inside the housing which resulted the rubbers to go soft and eventually crack. Another thing is that the air vaccumed multiple times to fill in soap liquid also crunched the rubber opposite direction. Very entertaining. I learning a lot from your channel. Very interesting

Great video

Incredible patience and detective work always pays off well done

Great content

Yep replacement hoses all the way great video.

The hoses are reinforced rubber, when you pull a vacuum on them you are pulling against the grain, they are designed to expand not contract. That kit might save time but its costing money. Essentially the hoses have a designed matrix embedded in them thats ideal for the forces involved i.e. straight line, curve t-piece etc. When you pull a vacuum you are reversing those forces. I wouldn't bother. That kit is more harm than good.

Older hoses will split after being put under a vacuum, even new hoses will at times, the vacuum draws all the moisture out of the system and the rubber hoses, plus the rubber hoses are built for outward pressure , great video I like these 👍👍

Love the car . Keep up the good work

After watching your last video I subscribed I find it fascinating

I had a 996 and those hoses do blow so worth ripping out and replacing that last big one that was clasping. Cracked heads are pretty rare from others i know in the Porsche club. I think you will find you got a bargain may man.

Use a conventional bleeding procedure, the hoses are compromised from the oil so the vacuum fill process is causing the bad hoses to break when they collapse.

You killed it with the shout video

Yeah, Randy. Go ahead and replace all the coolant hoses. No sense in dicking around waiting for them to fail one at a time. Looks like a giant win. Good for you!😃

That is crazy awesome dude what a hose.

I can see where the vacuum helps... what did contribute to the breaking of the already compromised hoses better yet find out now then on the road with the full regular coolant

In my opinion. You made a fabulous purchase. You have a cheap 911, with a new motor, and soon, all new hoses. Winning!!!!!

im really enjoying the porsche content bro!

Love the Porsche content. Fingers-crossed for your success. That would be a huge win if you could fix it cheap!

Love too see more big man. A big👍 from Thomas danmark

Oil in the coolant from water to oil heat exchanger. Common in german cars.

I love your videos Randy and I know almost NOTHING about cars ! My son's 1998 Porsche Boxter 2500L ground to a halt recently and the RAC man told him his engine was 'tight' after jacking it up ! The problem actually turned out to be the alternater and my tiny knowledge leads me to think he had ignored a warning light !!!! Anyway £200 rather than THOUSANDS OF POUNDS was a good outcome wasn't it ? Northumberland, England.

I like your work

Love it the content Randy xx

You need to look in to FCP Euro for your parts

If you are not loosing Oil and your heater is blowing hotter air than before then it is just residual oil as far as the hoses change all of them when it's running clean . As far as hoses they have shops that make specialty hoses maybe Oklahoma does aswell you might as well change all hoses that were in contact with oil

Definitely a win for shout... Seems to work better than dawn or other products I've seen or used

Fingers crossed for you Randy, sitting on the edge of my seat. 👍🏻👍🏻👍🏻

Great video 👍

You have a ground strap cable ground problem. I see the running voltage in your car at 12 when it should be around 13.5-14v. it's the ground strap that connects to the back of the alternator, starter, and the frame. cable costs around 50-100. You'll know that you really have an issue that after the car is warm it's tough to start, slow to turn over.

Yea that’s going to be a little issue 😂 Keep up the great content! 💪🏼💪🏼

Good luck buddy I'm not big on Porsche oh boy told you about the oil and rubber maybe all the hoses eh hope motor good for ya.

Mine as well...replace ALL hoses leading to heater, radiator...full-on assembly, etc, on n on!! Let that BE a lesson n leARN as U earn!!

Oh the suspense. By the way i have found rubber that has been saturated with oil tends to weaken.

When your done you could put waterless coolant into it as someone else has said the oil has made the hoses soft. Please change thouse alloy wheels

I think that you have a good engine and you are correct in your guess about the old coolant being left in the system,,, I would think that you would see fresh oil in the cooling system each time you ran it and that the oil level would be going down, if the engine had a cracked head,, :-)

I thought the vacuum tool was a great idea. Sure the oil had the hoses soft and the vacuum pretty much was the reason they failed rather quickly. You saved yourself a whole lot of headaches down the road and if you're selling it you can be confident you fixed all the weak points in the cooling system. Great videos I really enjoyed them and thanks for sharing the vacuum pump I'll be purchasing one soon. Keep making videos of buying and selling one of my great passions.

With as much oil that was in the cooling system its going to eating all the rubber hoses from the inside out. Your best luck would be to replace all the rubber hoses. It’s going to be battle. Find a silicon hose kit.

This is a Lot better than just waking around a parking lot looking at a bunch of crashed cars!

Look into putting a heat shield around that Y hose you replaced because it looks like it's resting in-between the exhaust pipes...

Thanks from Pakistan, you motivated me to flip cars, i sold my land cruiser 1995 and bought 2002 prado from auction

That little hose looks like a type of fuse, pressure release. Better that then the aluminum piping. Temperatures of all that piping around probably affects whats running through that little pipe.

If that small y hose was $50 at the dealer and the hoses are all probably damaged from it oil in the system you should probably replace them all, but don't buy them from the dealer. You can probably get all the rest of the hoses from an aftermarket parts house for the price of that one at the $tealer! Gotta love VW/Audi hoses, wonder what a hose engineer makes at Porsche? I agree on no mod's get out of that thing before you are in too deep, let the new owner mod to taste!

Hi randy Makes me think that the preasure sucking the pipes like that might be causing your pipes to go wrong if you think of a balloon that stretches if these pipes are old they would be already streched and now they are stretching the other way Just a thought Good work by the way

Oh, got my Dead As A Doornail shirt the other day, and I love it!

Uberman ! when the head is cracked white steam comes out the exhaust even when it is hot outside. This is not happening. Also the crank case will have water in it and this also is not happening. It is most likely fixed. Flush it out with water. I guessing you have success. Someone poured oil in the coolant and caused all these problems.Good fix. Your right oil soften up the hoses and probably more to come needing to be replaced.

Randy, just get all the rubber hoses replaced. Save the headache. Get it mechanically sound then worry about mods. FCP Groton was where I got my Genuine Volvo parts many years ago for my 1993 940GLE Turbo Wagon. FCP group is good in ensuring quality original parts.

I like the content with this car! Please keep it up. I know European cars are difficult to work on, but boy it pays off when they are running right! Believe me .. I’ve had dozens of them

Still my dream car you lucky duck. Even if every hose has to be swapped. Its still a 💎

6:30 Pro tip: When removing a bad hose, cut the hose before taking off clamps. You can move the pipes anywhere that makes it easy to get the clamps off. 19:00 Sounds like you need to replace all the coolant hoses in the car. They are probably all oil-damaged. Just bite the bullet, and replace them all.

Good video. The Porsche is a cool car.
