Hello all, it's been almost 8 years since I was on these forums last, I've recently done some huge mechanical maintenance items on my 1981 928, in short I have a few that I'm unable to do personally due to time constraints and moving so I am on the hunt for an individual or shop that could do some of the work. I am hoping it is fairly easy.

- Replace/remake high pressure power steering lines
- Replace Cam seals and take care of any other possible leaks if needed

I'm located in the Denver tech center area and would love to meet some other 928 owners!

Cheers!

Jerry Feather is somewhat close to you and may be able to jump in with a recommendation on some of the issues. However, the easiest thing to do with your high pressure PS lines is to send it to one of our vendors for a rebuild. I know that Roger does it, and Mark Anderson may, as well. I have what I think are some of Roger's rebuilt lines on my GT (not PS, but some of the fuel lines) and they're very pretty, as well as functional. Greg Brown may also offer a similar service but it's hard to get on his schedule.

Good luck

Thanks for the information! My issue currently is not being able to do the work myself such as pulling the lines and what not since we are moving, normally I'd wait till after I move but that might not be an option for a while

You just missed a great opportunity to find your best answer which would have been at the annual Gathering of Porsches in Dener which just took place Thursday evening. I don't remember where it was going to be held this year, but I have been to a couple or three of them. They were shooting for 250 or more Porsches this year. They had 238 and a half last year.

Your absence suggests that you probably are not even a member of the PCA. I recommend that you become a member of the PCA. That is the Porsche Club of America. Then also join their regional club for Colorado which is the Rocky Mountain Region, RMR. It is pretty much centered around Denver.

Although the PCA and the RMR do not focus much on the 928, that is changeing some I think. But interestiingly enough the RMR social events chairman, Eric Berenson, is also a big 928 guy. In fact some years ago he hosted the 928 owners club OCIC in Denver in about 2007. OCIC is short for the Owners Club International Convention.

There is also a Yahoo internet group for the 928 guys in Colorado but I haven't seen a post there for months. I'm not sure how to get you connected with it. I can't even remember the name of it. Get ahold of Eric and he can fill you in.

Otherwise I don't have a recommendation for you.

I will definitely do that! Thank you! I've only recently got the car to a running condition so I haven't been on the look for that sorta thing but I'm definitely going to do some digging. I've seen a few 928s at Cars and coffees as well I might try running into hopefully even tomorrow. Thanks again

I've personally seen dozens of burned 928's from power steering pressure lines leaking.
The leaks are generally pinhole leaks, which spray atomized Dextron generally over the top of the engine. Any source of spark results in an "explosion" of the atomized fluid.

Very nasty fires!

Very few cars with a power steering fire can be brought back to life (on insurance dollars.)

Not the place to gamble and save a few dollars on someone's idea that "This should work fine."

I've made 3 of these lines, from special high pressure Goodridge Hose and high pressure fittings, which are in cars, for long term testing. (Over 10 years without any leaks, so far.)
The issue is that with the costs of the materials I've used, these hoses cost more to make, than a new hose costs, from Porsche.

Therefore, until Porsche "runs out" of these high pressure hoses, I'm collecting all of the cores from the dozens of these lines we change in our shop (we are extremely proactive about power steering hoses.)

So, when Porsche does "run out" of these hoses, I will be able to supply a reliable, long term replacement.

In the meantime, buy a new Porsche hose.
(We stock multiples of these hoses.)

Definitely want it done right, same thing with replacing the injector O rings, rubber fuel lines etc. It's stuff like this why I want to get it done ASAP and carry a fire extinguisher at all times.

Just so you know if you’re going to pull injectors out of an S4 manifold that has original powder coating on it you’re gonna probably destroy the powder coating as the injector O-rings will be stuck to the powder coating and it will pull it free from the manifold necessitating the manifold be re-powder coated so that the proper fit can be obtained when you put the new injectors O rings back in

if you think painting is gonna fix it it won’t powder coating is what’s required to restore that fitting so that there’s no intake leaks

Shelden Finholm

Good to know, the car is an 81 with the spider intake 4.5L is that the S4 manifold as well or in the later cars?

Here is who I have used with good success. https://www.midtownautocolorado.com/ Jeramiah handles the phone and Scott is the mechanic that has worked on 928's.

Thank you! I'll give them a call
