Finally the engine is now back in the car after quite a stint on the side line. This episode covers not only putting the engine back, but also how we finish up the fuel line plumbing and the preparations for the engine electrical.
My goal has been to create a lean, modern classic using the Porsche 964 as the natural base. In this I try at every corner to apply modern electronics and engineering to make it what I call a modern classic.
This episode takes us through how to consolidate the cables on the engine creating a cabling hub and also a junction box with concentric connectors. We also cover how this is done in my CAD environment preparing the harness work to be done in E3 by Zuken.

Really enjoy your videos. I've researched a front mount oil tank for my latest 911 project and my understanding is that the scavenge pump moves a lot of oil and air: by design it will move a lot more volume than the high pressure oil feed side of the pump. Therefore there has to be a return path for this volume of air to the crankcase, which you are providing with the vent hose. Great job on that design!

You give the expert welder alot credit(and it's well deserved) but haven't heard anything about the machinist supporting you! Your machined components are absolutely beautiful aswell! För example that oilfilter/Thermostat housing!

CAM processing of a design and preparing it for the machine and tools available is half of the engineering. I work exclusively with Aximech on this. Fredrik (the guy behind) is the best I’ve ever seen at this!

Be aware you will likely end up with vapour smell inside the cabin if you're using that rubber hose and not Teflon. Common complaint with internal nitrile fuel lines in motorsport builds, and with fuel dilution in oil and oil vapour you might have similar issues.

If your running a dry sump with enugh scavenging you don´t need to vent the sngine, just the tank.

@islandworks Ай бұрын

I have a dual scavenge pump from Autoverdi. It’s about the largest you could have I believe. I do however feel it’s a small expense with a vent line if I have issues in the future with blow by.

@h-j.k.8971 Ай бұрын

@@islandworks Scavinging the sump creates a low pressure invironment, which in turn stops leaks and frees up power, it also helps the oil from being aireated.

@islandworks Ай бұрын

On the GT3 it is a return valve instead to allow vacuum to be pulled and at the same time allow positive crank case pressure to go via the line. I might look at something like that

@mawe42 Ай бұрын

The 19mm is big enough, but I would worry about the vent from the tank being a restriction, especially with that banjo fitting and even the vent from the puke tank. If you have a really powerful scavenge pump you might even push air back thru the 19mm hose, I'm guessing here.

@islandworks Ай бұрын

I guess some of this will have to be seen once the engine runs and adjusted accordingly

Hey Jonas, great video as always. I was thinking, would it be worth putting a pair of Dry Break Quick Release couplings on either side of your Gearbox mount and on the inlet and outlet of the engine so you can drop it easily for a clutch change etc. without having to drain and fill your Oil system every time. Those couplings look pretty expensive but it would be cheaper and easier than changing all that oil more times than is needed. All the best mate 😉👍

@islandworks Ай бұрын

It’s a great solution but I believe space will be the issue. I’ve found that whenever I end up doing a small job (in the past) I’ve always ended up changing the oil anyway, so I decided to rationalize them away

@TKRS480 Ай бұрын

Fantastic work, love the car, the workshop and I am green with envy. Regarding the oil pipe through mount, not an engineer, but wouldn't it be possible to get your TIG guy to weld more tube to make a little "S" in the pipe to make the angle more favourable? A little like you might with an exhaust? You have plently of spare tube, a friendly TIG welder....? Just a thought.

@islandworks Ай бұрын

Good idea and definitely a possibility! Another way to to change to a clamp rather than a coupling so it shrinks

@racingdatasystems3708 Ай бұрын

Just a word of caution (37yrs of Porsche race cars) we had an issue with the pump collapsing the braided lines close to the engine. We ended up running -20 lines and running a 150mm coiled wire inside to maintain the hose diameter. There is a reason why Porsche ran a hard line.

@islandworks Ай бұрын

That’s good input. I’ve taken reference from some other builds and in all honesty wanted to reuse the snout it comes with from factory around the engine but could not find mine…

@fraserwright9482 Ай бұрын

Poiseuille's law also affects you, as you are working with a fluid (oil) with gas inside it. You are not just doing this in a static condition, but as you brake/accelerate the fluid/gas acts as spring, the diameter of the pipe, length and to add complexity the viscosity of the fluid over temperature, engine speed are all changing the value. Add in the braided pipe which will deform at a percentage of length, which will also deform more at a higher temperature. Your pipe can be calculated to the necessary diameter of the wall required over the length and material of the pipe itself. Running hYeat shield between the fuel lines and a heat source of an exhaust is sufficient in the centre tunnel of a car as air flow is always linear, so front to back. Your oil is never going to be hotter than an exhaust.

@racingdatasystems3708 Ай бұрын

@@fraserwright9482 we also gold foil the tunnel to reflect the heat away and keep it out of the cars.

@islandworks Ай бұрын

So you’re saying better to run pipes in the middle and then thermally insulate the lines? Some reference from similar 911 installations have used more complex routing than this with AN16 or 20. In my case I have AN20 up the the transmission mount, then AN16 after that.

I think most people understand engines need the crankcase to breathe, but what are your thoughts on having a PCV actually pulling a vacuum on the crankcase?

In the sense that I mean a PCV as a non return valve on the crank case breather.

Sorry if I missed it, but is there a reason you can't use a VTE AOS and skip all that hose for the vent?

@islandworks Ай бұрын

Yes I don’t want to have two catch cans. The one I have is next to the oil tank in the front. You could have one in the back as well but I rather just have the hose and a single system.

@rossmacdonald3034 Ай бұрын

@@islandworkslove the car and do your thing. Seems like a lot of work to avoid a second can, but I've watched all the videos and can't think of anything you didn't fully think out. That said, are you worried about the oil vapors condensing and ending up as droplets on that long run of hose? Seems like a lot of vapors could cool, condense and end up as oil in the back half the hose and then run back into your intake. Kind of like the gooseneck you were concerned about. Anything that condensed on the front half would run to the tank so no harm, but the back stuff would be my worry. But maybe it's nothing. I sometimes both over and under think things.

@islandworks Ай бұрын

@@rossmacdonald3034 theres always more than one way to solve these issues. I’m not worried about any run back in this setup to the intake as the intake is not connected to the oil system at all. The vent line is directly from the crank case to the oil tank as compared to a standard 964 setup where the tank is vented off into the intake puking oil into the intake (ask me how I know…)

The oil lines are huge. Do they really need to be that big?

@islandworks Ай бұрын

The section line needs to be oversized to ensure there in no pressure loss leading into the pump given the extended length

@jonascarrerars9529 Ай бұрын

Yes they have to be huge. Its different in all other vehicles than porsche. In the 911 its a part of the system, not just additional cooler outside the system. This is What many builders miss. Its also very important you use a high flowing cooler

In my setup there are two coolers running in parallel.

So I guess we will be fighting a bit with the TIG. I hope I’ll only see gasses in the vent line!
