Oilline, looks like you have got right in amongst things in a bid to have a tidy engine bay, nice work.
At the risk of repeating myself... When I got round to thinking that a Porsche was other than a souped up Beetle with an engine bay that looked more like the innards of a washing machine compared with the likes of Jaguar and other classics of the time which had black enamelled exhaust manifolds, highly polished rocker covers, carburettors etc, well a 911 derivative has a difficult time when up against those type of expectations and perhaps more so when the engine bay may have an aged appearance...?
I had helped friends by stripping the engine and gearbox out of their SC Sport as they wanted to clean things up a bit, and boy did they make a fantastic job of cleaning and polishing everything.... though such is the climate in these parts that within a short period of time after re-installation, it all dulled down considerably, which I thought was disappointing given all the time and effort they put into the process.
some years back when I stripped the mechanicals out of my SC to replace the clutch, and upgrade to oil fed chain tensioners, I decided to have all the tinware blasted and powder coated black, and like you I had the cooling fan etc all blasted clean, and given the experience of my efforts on their engine, I decided to take the powder coating route with the fan, it`s housing and rocker covers too, at the same time I replaced the rusted old silencer with a stainless item. When I look back at the old photographs of it on the garage floor prior to installation, it all seems a bit too bling to my eyes, but once re-installed the engine bay was definately more colourful and easier to keep clean.... These days, I think I would be more impressed with clean and tidy components in their original finish, though on an older engine that would seem to be a difficult if not a very expensive process to try to replicate..?
Those guys with modern machinery such as Jags and Mercs etc that have plastic covers over everything have no such issues, and as for the latest Porsche 911`s and what can be seen in their engine bay...!!!! Yup there is no holding back evolution and trying to make an electric motor look impressive to an old duffer like me...hmm :?:
It will be interesting indeed to your choices, good luck with the processes :thumb:
