Where's that left hand oil line coming from?
Didn't you read the article in the link ?

Cheers Panel.

Couldn't sleep last night. Ended up getting up and measuring a few things. Then I did a google image search...

https://www.google.com.au/search?q=pors ... _HXcQxW8WM:

Which was about when I realize my tank was a LOT bigger than it really needed to be. Turns out this issue is a pretty common and easily dealt with scenario in Porsche 930 land. So what I've ended up with is about half the size of what I had before and is pretty close in layout to the Pelican parts one (only without the cost).

Image

This is 1 3/4" exhaust tubing with some 5mm plate that was offcuts from hole sawing things a while back (I knew I kept them for a reason). So I welded up the centre holes and stuck the whole thing together with the MIG. Then I drilled one hole and pressure tested it. :D Happiness.

Image

The pipe in the end goes to the turbo drain. (No I can't install it on the turbo ala Pelican, or it would be impossible to get the turbo in the car.) The other end has a small fitting tapped higher for a vent, and a lower bigger fitting for the scavenge pump.

Image

So I need some fittings, some hose and a mounting system, but I'm sure that will be easy enough. I think it will hang off the headers. It is a little heavier than needs be, but I've saved myself about $200 in labour and parts doing it this way. So we'll call it a win. I've also dramatically improved my MIG welding skills on this project. I used much higher heat settings with lower wire feed and it's pretty great.

Image

Coat of paint and it's ready to install.

Just back from the turbo shop. Turbo is in excellent condition. I need a reservoir (ala Porsche 930) to catch the oil for the scavenger pump to work properly.
I just want to add to this. The guy who runs this shop was awesome. Precisions Turbos...

No nonsense. Helped me out straight away and charged me nothing. If you're in Sydney, this shop is great. :)

The problem is there's too much air in the pipe, so the scavenge pump can't lift the oil. The tank allows the oil to collect so the pump can draw it from where it can be scavenged properly. ;)

Why would you want a vent in there???

I would think that would just add more air that would have to be pumped by the scavenge pump and then mixing it all up and sending it into the valve cover.
Unless the pump is creating too much of a vacuum on the turbo.......you could then maybe vent it to the fuel pump cover or something.

Why a vent? Atmosphere pressure helps the oil settle. Porsche have the same setup in their factory oil cans.

Well I've crying myself to sleep every night missing you all with the upgrade taking longer than we all thought...
:cry:
...but I haven't been sitting on my backside. :)

The new oil can is in the car and it's all running.

IMG20170313182849.jpg

The first thing I adjusted in the tune was the idle. Autotune had pushed it up nearer 14.7AFR and that's not happy.

I've not given the car a hiding just yet as I needed to get my son to and from basketball on the weekend. Sadly that's the end of basketball. He's totally over it and is dropping out of the team. He won't even do the last game of the season on this weekend. No one passes and then the team tanks in the last few minutes as the heros are out of steam. Basically the coach(es) have failed to stopped severe ball hogging and he's barely touched the ball all season. The only ball he got from a team-mate on saturday was an accidental ricochet that hit him in the head. Beyond that, the "good" players never pass to him. Sure, he's not great, but he was trying. :x

Anyhow, rant over. Back to the car. On saturday I gave it a wash...

IMG20170318153711.jpg

Ok, so maybe I left it in the rain and just wiped it down. That's the wash for the year. The paint falls off it anytime I try to do anything more. I waxed it on sunday and found more PO (previous owner) problems. There's bondo in both doors. Hmm, will have to sort that out some time. Grrr... :x

I also found the PO had done this to fix the seat. Honestly, what's wrong with the guy? When I bought the car it had no seat belts. In an accident, he would have gone through the windscreen WITH the seat. He owns a welder (I know coz he does birdpoop welding), why didn't he just weld it on properly?

IMG20170318160608.jpg

Anyway, back to my hackery. I pulled the seat, coz I spent most of Satuday working on the mounts for this...

IMG20170318143652.jpg

So I got the back adjustment rod out and made up a bracket to hook onto that. Then there are 2 pieces of angle welded onto the sides of the old seatbase. The seat bolts up in 6 places. I got it in the car and it fits well...

IMG20170318155523.jpg

...well sort of. I took it round the block and noticed a few things. "Seat of the pants" came with a whole new meaning, LOL. Secondly, this is not a "drive 1000 miles seat" without padding. Thirdly, the steering wheel and the side of the seat are just a little too close for comfort.

IMG20170318160253.jpg

That's ok, because my machinist friend is starting on my steering wheel blank in a couple weeks. I've got some ideas for padding too. I just need to make the seat a little less obvious. In the meantime, the seat is back out of the car while I paint the base the right colour. Got a spray pack from my local auto shop to do that. Just waiting for the humidity to drop a little around here. Feels like south east Asia. 25degC and 100% humidity.

What have the rest of you been up to?

Well, I found out what was wrong with the fuel system causing the petrol smell on lifting... the fuel cap was loose. Yes, I'm an idiot. :roll:

In other news, I'm able to tick off little stuff. I'm trying to find the glovebox out of the car. It's been out of the car for about 2 years now while we rewired things. I wonder where I put it? Hmm...

On most forums, my username is "slowlearner". And this is why...

IMG20170321215640.jpg

Having searched the whole garage, my office and some other parts of the house I could not find the glovebox liner. I kept thinking, "I know I've seen it recently". But I couldn't put my finger on where. In desperation I went looking under the car seats in the car. When I lifted my eyes it was right in front of me. :roll:

When I did pull it out I realized how bashed up and cracked it was. Having tried superglue (and failed) I pulled out the titebond.

IMG20170321221957.jpg

The first go worked really well! So I've glued a new section this morning and I'll post a finished pic. Pretty happy with the outcome. :)

I need to drive the car on Saturday, so I'll be setting the lifters (they were quite noisy) tomorrow. Then hopefully we can do some more tuning.
