Hello from france ! Is this the mivec md or mivec rs ? 2 or 4 wires on the mivec solenoid?

I think this system has a frequency valve. The nature of the rpm drop at idle..the way it suddenly cuts out and raises back up again, seems electrical . The frequency valve is electrical. I would rule out any relay controlling it and or the electrical connection to it. On my VW with CIS injection, it is easy to diagnose because the dang thing buzzes so dang loudly when it's working. Yours may not be as buzzy. Hope this helps. Good luck! You may dread this car, but of a CIS guy like me, this content is awesome. Keep it up!

The auxiliary air valve is open when the engine is cold to add air in concert with a cold enrichment valve (aka warm up regulator) and closed when warm. They are supposed to open and close in time with the heating and cooling of the engine. Essentially, it adds rpm while the engine is cold and running rich. Heating and cooling cycles take a while, therefore, the axillary air valve moves slowly. That is my understanding, anyway. Love the content you produce, keep it up!

I deleted my aux air valve but also not running A/C

You seem to have glitched at 0:10 lol

Define “crazy hot” 😅 (laughs in South Florida weather)

Dude, you missed the opportunity of turning your intro a famous meme with that chair throw…it needed to be open the whole way before hitting the ground! 😁👍🏼

What corvette driveline did you swap in?

Road and Track article on the 928 back in '78 made mention of the loud fuel pumps audible inside the car. My '79 is the same way. Mine has both internal and external pumps. Decel valve slows the rpm drop when you release the throttle and you might hear a little popping in the exhaust when decelerating after you delete it. Also, without decel valve if you blip the throttle, rpms will dip below idle then stabilize. AAV should close fully, otherwise you'll get erratic idle speeds.

That 1.4t seems sturdy enough to come out to Texas vs the world in September vw race and car show.

Yes to all you said, I even reduced the number of videos I release from 1 per week to 1 per month, to focus on other things (like building the new garage I'm making), but I still try to deliver videos with content that will help and motivate people instead of just entertain for some minutes and be forgotten. I read a comment here in this video "Just build what you love and share whatever you want.", I agree 100%. Thanks for the videos Jeff and I have to say, what a beautiful image and sound quality you had in this one. The colors of the cars are really cool and filled the screen. Cheers from Brasil, Paulo

Thanks for doing what you are doing and keep up the good work! Your MK1 VW videos have been very helpful to me as a fellow MK1 owner.

Thanks for the video fellow Washingtonian.

Thanks for making videos. 😊

Thanks for the perspective

good video

way to go Jeff.

Use a dry sump, and don't be afraid to modify the front traverse beam. I love your videos. This will sort itself out, I am sure😊

Just build what you love and share whatever you want.

Greetings from Costa Rica, love your projects! Keep doing it .... Even if it's for fun😂 no seriously... Great work! My mk1 GTI will never see a 1.4t on it, but who knows what else the future will bring...

That's probably the best way to get rid of my noisy 044 style pump probably but I'm probably gonna stick with a cabby in tank fuel sender... if I can ever find one that doesn't break the bank. 😅

Thank you SO much for posting this, was looking at a set for my CS. The sets are so cheap I really was leary of this company they have no information about their company on their site

Did the fuel pump solve all the driveability issues?

Hi I’m from down the street.

I freakin love that rabbit. I was at radwood last year and wish I had my 80 copper colored rabbit again thinking that cat would be a blast with my 2020 1.4t in it...bam! Found your channel!

Sr I’m here for mk1 1.4t content and information! Car looks great and I’m looking to possibly do that swap in my1983 Jetta.

Running? You trying to be President?

Hi from Australia. Throttle Grotto, "Home built by Jeff' and "Tools and track" are my three go-to weekly watches. What keeps these three as standouts, is that they show a 100% accurate, warts and all insight into modifying and working on cars, and that really resonates with me and my own car projects. These three channels are head and shoulders above the blizzard of shallow, unrealistic car mod channels that magically get it all done in a weekend with no fuss, to which I call bullshit! Keep going with your projects and show us what you are up to when you get a chance. We are all watching and genuinely interested in what you are doing.

Hi from Canada! Hope that makes you multi-national and ups your KZfaq cred. 😂 Appreciate your sticking with this. I've been around since the NX days and your skill and ease with the camera has grown considerably. Looking forward to more.

I bought a ring from dumpy bunny a few years ago and I am just now getting around to do exactly what you just did but for a 1.8t swap. Very informative video. Thanks for posting it.

So how does it sound?

I love the effort of the dash and itd well worth the experience. Dont feel down, this is the process and i love this car. Mine is rusted really bad and im hacking and replacing it all myself.

How can you 'balance' one carburettor??

Going to be following closely. I have an equally crazy dream to F136 swap a 944

I've watched this several times and now I'm finally I'm considering this method on my gas converted 81 diesel. I'll have to see if the tank baffle is similar.

Where did you get your center caps? It’s hard to find original ARE center caps.

You certainly dont give yourself enough credit for the stuff you accomplish. Just because your channel doesnt get thousands of views within hours doesnt mean the content is lacking in any way. In the end, if anything, it shows the reality of building cars instead of the glamour that most big channels try to project. 👍🏼

Great to see your still in one piece 😂. But would it have been easier to upgrade the pump in the tank or bigger pipes from tank to engine under the car ? Or is it all down to the mk1 golfs / rabbit swirl pot being no good ?

Copied from Dumpy Bunny, that tank pump billet piece. Give Ryan the credit for that one. Just like the billet mounts for the 1.4t to hang in the mk1 bay, also Ryan.

Great job on the getting the fuel pump in! I have heard of people would put some dry ice in the tank before welding a gas tank.

What aize is the tank?

Hey man, I need to see if this ring flange will work with the Honda Fit fuel pump. It looks like the same lock ring. I've searched the site you linked and can't find it. Do you have the part number? Great episode!

Keep making your videos. They get better and better 💪

Were you ever able to the get trans working for you ?? I bought a used 5 speed and had a guy who used to race them rebuild the whole thing.. NOW I have to put the car ALL BACK TOGETHER AGAIN >. If I can remember where all those bits go ..

How did this end up working out? I have a '79 in Minerva too, and need a new bottle (mine is cracked). I've heard mixed things, and really don't want to go with the compromised Mercedes alternative.

Not sure but it looked like the check vale was flush but it should be a bit lower because if the engine gets hot it could get stuck and stop the oil flow i reccomend you check that again

Progress!🎉

Great video . And keep at it . Really enjoying the videos

Moving forward

great job!
