The problem is you only have one broom holding the bonnet up you need two so it goes broom-broom properly.

[@HomeBuiltByJeff]

HAHAHA. I love a bad Dad joke :D

[@brunojanz]

Ahahah That's a good one!

[@bigmac60]

These jokes really make me bristle

[@8700s14]

Commence slow clap

[@simonbright1374]

You need to brush-up on your jokes.

[@witchcraftauto]

The beauty of your struggles is that anyone looking at doing this engine swap in the future will have some very detailed videos to follow with. Really been enjoying binge watching this series!

[@computiNATEor]

You’ll get there, Jeff! Keep learning, keep building. 😊

[@rpeterson223]

Despite the challenges with the cooling system, love the exhaust note you created.

[@TheLeonardwilkinson]

Great work Jeff! Hold in there 🫶🏼

[@simonbell9476]

I'm no mechanic, but I always knew you'd have problems after taking the door stops off. 😆

[@matsleight]

Glad to see the Roxster back!

[@HomeBuiltByJeff]

I have been working on it in the background for a while, it is just hard to get motivated when I keen struggling with little problems ;)

[@markprobert]

In case the airlock returns, air gets pushed around hoses under ~15mm, but collects in high points of larger hoses. If you are getting air locks, just tee off a narrow hose from each high point into the vent hose to the expansion tank, and it will bleed though that. Had similar (resolved) experience with Westfield V8 (with 2 high points in the fat hoses).

[@danielprivate7442]

Take a piece of PVC pipe about 45cm long, hold one end to your ear, plug the other ear with your finger. Now aim the other end of the PVC pipe at the engine. When the end of the pipe is over the spot where the noise is coming from, the noise will get loud because the sound waves are going right up the pipe to your ear. That's how you find where a noise is coming from.

[@adamgilesconcoursdelegance9302]

Thanks for making all my nine cars seem simple to look after 😅😂

[@al8161]

Check the cam chain tensioners on that 4.2, they go bad and you have to take out the timing belt to change them. They also make a horrible sound when they fail.

[@leebuckles2364]

You knew the rockster would fight u all the way Jeff but I am sure u will get there

[@alman6581]

10 points for effort Jeff.

[@alman6581]

I've been looking at a similar project myself, especially now Boxsters are becoming so affordable and engines with bore scoring scaring many owners. A power swap makes a lot of sense.

[@donfinch862]

A quick note.... a water pump can run without water. The bearings don't need it and the seal is carbon against ceramic which don't need water. Could just be cavitation noise - air in the water. I'm sure you'll sort it tho Jeff. Good luck.

[@jimclarke1108]

Plush pile carpet thanks, Jeff👑

[@robwhite240z]

A water pump does not run dry, but you do have a air lock in the cooling system. That sound is air bubbles in the power steering. With the motor running turn the steering from lock to lock buy the front wheels, not the steering wheel, to bleed the air out of the power steering system

[@Ash_Simo]

You should do an Astra electronic power steering pump up the front of the vehicle.

[@mackellmo1083]

Takin out the engine again! Classic Home built! Love it!

[@lawrencemercieca]

If you want to test the water pump, when you have the engine out, grab a drill, a drill attachment that acts as a disc to stop a belt sliding off and a belt You just put the belt on the pump and spin the drill, you will be able to run the pump pretty well and can easily tell if it’s working, I would also run it without the thermostat while you do that test, no use restricting yourself

[@deopersad2915]

Awesome yeah it's all a learning process, you will get there 👍🏽🤙

[@DanielvanKATWIJK]

Your thermostat is in a place where it stays cold. So it will never open. You need one with a little hole in the plate that moves. That way there is always a little flow that goes through the pipes heating up the thermostat. Than it will open. On my French cars I had this kind of thermostat (305 Station Wagon SR)

[@nickframe6743]

Draw out your cooling system on a whiteboard with arrows for your flow, it might help visualise where the problem might be. Just remember to also draw the components relative to what height they sit at in the system, this will help show where air pockets might develop.

[@joshevans4529]

Drilling a small hole in the thermostat is always good to help any trapped air pass through so there's no air pocket against it

[@stevenwest1494]

Yikes that's a big job to investigate! Can't be made any easier with engine accessibility. I hope we see the Boxster running sooner than later with the help of somebody out there. Thanks for the video

[@teamvid9454]

TeamVid 0 seconds ago Nice to see Roxster again, all the best fixing the problem. We know you can do it. Hope the Alfarrari Ferrari engine goes smoothly.

[@Torch4ya]

This is why you should redo the seals on the front and rear of the Alpha, my bro! Service the service items before they service you 😆

[@bubbleobill267]

Yay, I’ve been waiting for a donk to be either removed or installed….:D

[@boatbloke6701]

Hi Jeff Are you certain you just haven't got an air lock? I had a similar problem with my LS6 engined BMW after a rebuild. It would slowly overheat... I tried everything, I convinced myself I had fitted the head gaskets the wrong way round but I hadn't, I convinced myself it had a crack, it hadn't, I bought an electric water pump, no change,I bought a vacuum filling tool, no change, I fitted extra steam vents, fitted a bleeder in the heater hose, made a new top hose adaptor with direct connections to the header tank, bypassed the thermostat all to no avail. At one point it blew the expansion tank apart. I must have drained and refilled the engine twenty times. eventually I connected a small open central heating overflow tank to the top hose of the radiator and let the top hose from the engine empty into it where I could clearly see what was coming out of the engine. At first it still overheated but I clamped off the pipes to the heater and header tank and this huge amount of air came out. I let the clamps off the hoses and it was still fine, reconnected the system and its been fine ever since. Sorry its a bit long winded but believe me it took weeks of tearing my hair out to get to the bottom of this,and whilst I understand your engine is different it may help... Love the channel, keep up the great work!

[@motomenace86]

expansion tanks are simple. The main feed goes to the water pump or as close, most cars that's the radiator hose that feeds the water pump. The two "breathers" are steam tubes for self bleeding. Alot of cars only have the one steam return. The fact both radiator hoses are cold tells me theres no flow at all. Even with a closed thermostat there's a bypass so will have some sort of heat in them.

[@danijuggernaut]

Come on Jeff, you are a mechanic and a good one !!!

[@cestusfr]

This Porsche wants to be a Porsche! It demands a Flat 6! ^____-

[@SeanOBryanZZ]

Man that sucks. Luckily the car is in the right hands! thanks for the videos!

[@chocolateteaspoon]

12:30 looking at my own 4.2, that welded bit is a return to the tank and also Ts off to the top rad hose. The curved pipe to the right of it is the feed from the tank

[@gazzafloss]

Looks like Scotty Kilmer is right Jeff, those Porsches and Audi's are "endless money pits". 😂 Would it be practical to use an "in line" type electric water pump? Power steering pumps are extremely noisy when they're low on oil.

[@benhowe2087]

With the system not holding vacuum, wouldn’t there be a water leak? I think fill the system with water as best as possible. Then pressurize it. See where it is leaking. Before you take the engine out. If the leak is very slow you can let it sit over night and keep pumping up the pressure until the leak is located.

[@billweston6579]

A trick we used to do on early BMW’s was to drill a small hole, 1-2mm, in the top plate of the thermostat at its highest point. This would allow any air behind it to bleed out. Stopped many a car from overheating.

[@HomeBuiltByJeff]

It already has one standard.

[@billweston6579]

@@HomeBuiltByJeff hopefully the extra line will help and you find something wrong with the water pump.

[@austinmorris3970]

Sounds mighty nice that Jeff 👌

[@icbtech01]

Pressurize the cooling system to locate the leak, it might not be necessary to pull the engine. And a stethoscope will help you pinpoint the noise source.

[@XiraArien]

you can also add tracing dye into it. makes detecting much more easy

[@George-xi9bh]

Great episode Jeff, but can't remember seeing anything about a race car interior!!

[@MrCaprinut]

Both pipes is cold because the water pump is broken mate!

[@paulladdie1026]

take the thermostat out, and check the radiotor temp

[@enricodigenova8112]

I’ve seen similar problems and it end up being a head gasket hopefully not but maybe something to look at

[@markwalton8644]

Sure could be. Perhaps Jeff needs to do a leak down test before removing the engine!

[@anomamos9095]

A common tear your hair out problem is having the impeller fall off or even disintegrate .

[@dra911]

Would it perhaps make sense to look at the Audi's cooling diagram and then try and best replicate it in the Boxster? Do you know what that port did before you blocked it? Anyway, I'm sure you're getting plenty of "advice" so you'll sort it out ;-)

[@williamholmes9129]

Can you not just bin the thermostat and fit a davies Craig water pump and controller? May also help with bleeding and circulation. Also can you bin the hydraulic power steering for a small electric power assisted column? Although might also have to source a non power assisted rack 🤔

[@peanutbutterpadre1519]

power steering delete + light weight wheels

[@rjung_ch]

or an electric one.

[@neilb6029]

I think that noise could be timing chain, if it has one. What made the smoke?

[@_kostoberina_]

Well, the thermostat on all of the cars I've owned opens at 92°C

[@Ren200Z_MotoringLife]

could it also possibly be the power steering pump making all that noise. i know my Benz was making some rattle noises before i replaced it. iam more than sure youll sort it out..

[@andrewgates4904]

Could the noise be the power steering pump dry of hydraulic oil? I had the same recently and rattled like that

[@MicahBell_1860]

If it's worth doing, it's worth doing thrice!

[@LeighHaines]

pretty sure you can run a water pump without water....they just have sealed bearings.

[@xavierwalker4639]

🤙

[@chrispainter3590]

Have you got a steam port on the highest part of the engine I had this same problem with a lotus engine conversion

[@mrh6577]

Is your water pump working?? I should have watched it until the end 😅

[@blackdatsun]

Sorry Jeff, After your intro my first response was IN THE BIN. haha Sorry again about MCM reference.

[@seanalexander9531]

That's a bugger mate. Even as an ex-mechanic I can see that this would be frustrating!

[@markim5087]

Subbed..

[@HillSideKonnection]

I think the engine needs to be gone through and have erroneous factory parts removed that aren't needed for 'race' use. Should make troubleshooting a bit easier IMO

[@mikestrang6229]

I have some sage advise----- there is no problem that can't be solved with the proper application of high explosives.

[@WillPittenger]

Did you go to the Bathurst 12 Hour? How about enter something in the race. I hope it wasn't you wrecking cars on the mountain. It tends to take expensive race cars and spit out just a bunch of parts that head straight to a scrapyard.

[@TheLeonardwilkinson]

Electric Water Pump?

[@slothcunt8353]

Damn Lambada is not right. You know how important the Lambada is😉

[@andremarais2706]

Clogged water jacket in the engine block?

[@300DBenz]

Both of the tubes being cold just screams “Water pump” to me, VW (and thus Audi) used plastic impellers on their pumps and they have a nasty habit of breaking off inside the engine.

[@MattiaRaffaldi]

It's a racecar, why you don'y just remove the termostat? Simple open circuit. I would do the same for the power steering, one thing less that can break at the trak. Or maybe an electric one, so at least you don't loose liquid on track if it broke.

[@rjung_ch]

Jeff, will you get that oil temperature working later as well? Still watching the water temperature part.

[@HomeBuiltByJeff]

Probably, I need to install a sensor.

[@davidvincent2838]

Oh Dear mate, the old Rockster, keeps on giving unwanted gifts, AND just keeps on giving. That noise was pretty bad and loud even on the mike. Hope it's nothing too bad. When you said water pump I thought it did sound like a pump bearing failure. Just crossing my fingers for you that its not internal.

[@b3nny90]

Sadly my money is on head gaskets. I'm hoping it's a simple fix and I'm wrong though because I'm keen go see this back out on track.

[@CesarPerezn]

That's why you LS swap everything. You'd have been done already.

[@Kiwi-pp7rg]

Its worth if it has a vacuum pump to disconnect it, when worn they sound just like rod knock

[@hasbeengood]

I hope the water pump was not the one with a PLASTIC impeller. If that breaks, it goes everywhere in the engine galleys. If you change the pump, take one with a metal Impeller.

[@florasdad1]

Feel for you

[@marcosdarriba]

Good morning Jeff, I’m think this engine is dead ☠️, sorry more job 😂😂😂 ❤

[@JTGaffley]

Shame bro that's terrible, I was listening to Matt Watson on the unreliability of old BMs and was surprised he wasn't talking about an Alfa! Now Audi's too... Oh, the joy' of a 20th-century garage!

[@holdencaulfield1001]

Hey Jeff! Have you been watching American KZbin car repair sites? They say lift. I think we say hoist.

[@HomeBuiltByJeff]

Better than the Poms who call it a ramp??

[@stevenhorne2667]

It’s a lift mate, from a Pom

[@nickframe6743]

A hoist pulls from above and a lift raises from below in my automotive world 😂

[@georgebettiol8338]

The definitions of hoist, lift and ramp respectively in the Oxford dictionary is: 1. “to raise or pull something up to a higher position, often using ropes or special equipment”; 2. “to raise someone or something or be raised to a higher position or level”; 3. "a slope that joins two parts of a road, path, building, etc. when one is higher than the other. Based on the above defintions the more “descriptive” and in my opinion correct term is vehicle hoist as the "machine" effects the raising of the vehicle by use of wire ropes and pulleys and a hydraulic ram. However what the Americans use - i.e. lift, is inherently less descriptive but appropriate. Needless to say the use of the term vehicle ramp to describe a vehicle hoist or lift is simply erroneous. However, all of the English based TV car shows that I have viewed (e.g. Wheeler Dealers, Flipping Bangers, Salvage Hunters-Classic Cars, etc.) use the term ramp. Mmmm - English based shows not adhering to the use of the Queen’s, err Sorry, King’s English - sacrilige.

[@Pull_It_Apart_Paul_Ham_CB]

You must ignore all the cooling on the Porsche, and only use the cooling diagram on the Audi. The audi engine needs to cool, not the Porsche car.

[@ToasterCoasterAdventures]

Correct, all the boxster motor swaps Ive seen have had the same issue when using the boxster expansion tank, I have told him before, but jeff is always one to try his way haha
