Quick update. I just bought two pints of something that Greg Brown recommended, called Swepco 502.

A fuller description is in post 147 of this thread.

The back side of the bottle explains that apparently one bottle (16 fluid ounces) is good for 5 quarts of oil. 8.45 quarts of engine oil in a 928 means you need 27 fluid ounces of Swepco, or 1 2/3 bottles of the stuff. In other words, buy more than one bottle if you want to treat your 928.

Hi Scott,

It's fantastic to read of yours (and Mike Fryeĺs) write ups of your S3 intake adventures. For my sins I too am considering going down this path, so I can't thank you both enough for going to all the extra work with your write-ups.

Before I do I thought I'd ask if you'd had any reflections on the work completed since it's been a couple of years. I'm also wondering how the CopyCad process has held up after some time (and heat)?

Is there any other advice you would give a would-be intake apprentice?


My thread is here if you want to get a sense of how newbie I am: https://rennlist.com/forums/928-foru...o-project.html

Hi OPM928,

I consider myself an apprentice as well. Luckily there are many masters here on Rennlist to help us.

CopyCad holds up under three conditions.

1) The metal to be plated had to be clean before plating. Otherwise, the plating flakes off.
2) The metal had to be plated for enough time. I did a write-up here.
3) It is much better to very lightly clear-coat the plated parts. Bertrand Daoust (definitely NOT an apprentice- look at his car sometime!) turned me on to this technique.

You claim to be a newbie, but judging from the work on your thread above you have far more mechanical acumen than I do.

The plating will slow you down considerably. Since I was plating each piece by hand, one or two at a time (down to every bolt) it really slowed me down. I used it as an opportunity to clean, clean, clean. If you have access to a professional who can plate parts by bulk (and use the original cadmium plating process) that is going to give you better results in the end.

Don't be surprised if you have to buy more parts than you originally ordered. I think I received six or seven "care packages" from Roger Tyson- even though I believed at the time that the first order was exhaustive. You will find broken hoses, broken clamps, and other "fun surprises" as you dismantle the intake. When I did mine, I changed the coolant reservoir-- and I regret not changing the washer fluid reservoir neck as well. I ended up buying new fuel pressure damper/regulators because they were not holding vacuum.

I hope you enjoy the intake refresh project-- it is really a lot of fun in the end. You can ask questions here or PM me anytime. Good luck!

Thanks so much Scott for your encouragement. First off I'm going to finish the current jobs, then open up the 'organ pipes' for some exploratory surgery. From there I'll just play it by ear...
