So not quite as the clock told the story. I took my manifold in for blasting, as the VHT paint hasn’t lasted too well. As luck would have it, my tame powder coater has begun learning how to ceramic coat. So it was agreed I would be a trial customer for one of their new products.
I fail the before photo test. I ask for the same bright silver id used to match the rest of the engine silver. They had titanium silver in stock. So gave it ago, unfortunately it came out very grey.
As they're kind souls, I asked them to make it more silver. So they ordered in a much brighter tone and this is what was return to me.
Ignore the silver over spray on the underlay, thats from a previous job. But I had to say, that manifold looks exactly how I want it too.
This ready and waiting I thought I best get on with bolting in something for it to attached too. Though there was 1 more modification to carry out first. Its not uncommon for the 944 to spontaneously combust. This is often owed too the two flexi fuel lines in the engine bay. they're 39 years old on this example and now being exposed to ethanol. Small a mounts, but none the less some.
These are swaged on to the steel fuel lines which run the length of the car, and this is a dock yard job to change them. There are a few kits available for replacing them, but they're a bit pricey for what is effectively two rubber pipes and some compression fittings. I decided id work it out for my self. I started wit the tube cutter, and removed the main feed. Gulp.
Several steps later Id been and had these two pipes made and bought an 8mm and 10mm steel compression fitting. Good for about 500psi.
They unfortunately put a BSP fitting on, rather than a metric fitting, so I went back and they made me a new pipe free of charge.
Once id mocked them up and was happy, I etched and passivated them.
Access is tricky as they're behind the brake booster. But with the head and inlet off, I was able to get them installed. I will buy a couple of spanners and modify them for future use. My intention is to change this pipes every 4 or 5 years. As its now a relatively simple job to change them.
You can just see the fittings in the back of shot here. And as if by magic the head was reinstalled and the manifold was mocked up. It was at this point I was a bit stuck. Id ordered a replacement set of exhaust manifold washers from Porsche, which were on the long lead time. Id planned to swap them later. But realising how much of a curse word it would be to do. I decided id wait a bit.
As luck would have it I had to wait 2 days, as soon as I got the email saying they were in stock. I shot up to the dealer and collected them. This is why I needed new ones. Beyond saving.
With a couple of other bits I don't really need.
Some of you may have noticed the brake booster was looking a bit rough, this was from the dipstick tube when I removed the sump. I hadnt realised what id done, until I got out from under the car. This simply wouldnt do, so out with the masking and sand paper.
There cant be much left to do now can there?
