That is excellent work, this was an MOT advisory last time my car was checked, although my indie did say that there are years left and they look worse than they actually are.
Leading evidence: 'Check although my indie did say' (no explicit attributable resolution; this is a reported action or suggestion).

I offered the brackets up to the engine and tack welded the new ends to the tubes the removed them to weld properly although I haven’t got a tig so I used stainless sticks in my arc welder
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I thought I’d do a wee write up on what I did to recycle my rusty hangers.
The hangers on 996s and 997s often corrode really badly in the lower section that bolts to the head near the manifolds.
The hangers are made of Stainless 15mm tube but with mild steel ends and also the central webbing section is mild steel.
This is what the lower laminated section often looks like
This is usually the only part of the hanger that is beyond help , the central webbing and the top section don’t get as bad due to their location
Top section with very light surface rust
So to remove the rusty part you need to grind the top layer off where the tube comes through until you see the tube.
Then peel it off and release the tube
These are the new stainless ends
I offered the brackets up to the engine and tack welded the new ends to the tubes the removed them to weld properly although I haven’t got a tig so I used stainless sticks in my arc welder
The original ends are 9mm thick ( 3x3mm) and tubes are inserted 6mm so 3mm short of being flush. The new ends I had made are 6mm so I pushed them in halfway.
I hope it makes sense
These are for a 996 3.4 and I think the 3.6 and 997 s were a different shape so it would need someone to measure and draw them up into a CAD file
Reason for doing it is new hangers are quite expensive and it’s a shame to waste 90% of something for the 10% that’s letting the side down …I also love to recycle/reuse stuff.
That is excellent work, this was an MOT advisory last time my car was checked, although my indie did say that there are years left and they look worse than they actually are.
You don’t fancy doing mine do you
I think that's very true , my one in the photo above looks really bad but it'd most likely be fine for a few more years.
I just thought I'd do it whilst the engine was out.
I was thinking of maybe doing it via mail , you send me both hangers and I'll do the work to fit new ends but I'd need a cylinder head to fit them to for alignment ideally.
Also you've then got 2 way post cost on top of actually doing the work and it gets to be pricey and buying new ones start to appeal. It's a tough one.
D911 want £550 + VAT (£660! ) for a pair (free postage) so there is some wriggle room. I'll get a quote from Porsche today.
Edit..Porsche are about £620 for the pair but you would have to collect.
God son drew them up on Autocad to my drawings , I then took them to a local firm that made them.
They're milled so look very nice but they really don't need to be , laser cut would do I think and probably cheaper. I'm looking into that now.
the 997 look to be longer.
Does anyone guess the reason ? It looks very complex and would have been a pain to construct. Guess mild steel press cut would have been cost effective?
I can measure the hole centres if any one can do the CAD thing/ and or make up. Brother in law has some contacts but he immediately asked what’s the purpose and why the openings and design. As I’m not German and involved in the construction in 2003 I cannot answer.
I’ll try and search better next time.
Water jet or laser cutting would be ideal for these and cheaper than CNC. I'm a designer and work in manufacturing I can easily knock some quotes up if there is demand. I don't see why they have to be so thick 5mm plates would be plenty strong enough.
I would have course it depends on cost, as these seem to be quite common I would think enough people for a group but ?,
from extra research it seems like the top bolts are tricky/impossible with engine in car. I’ve not looked at mine physically to confirm but guessing that might be the case.
Mine are 6mm and yes I've got 3 pairs on the way from a friend that has a laser cutter , I'm hoping he can do them cheaper than the CNC ones , I think they will be.
