I've just finished updating all four parts of this article, which details how to;
1. Drill and tap your Type 1 engine case for full flow oiling, as well as;
2. Locating and installing an external oil filter and cooler at the rear of your car, along with;
3. Installing a pressure-limiting cover on your oil pump.
All sections are illustrated with full color photos to better describe the process. Those photos had been missing from the original articles after a major policy change from Photobucket, a once-useful photo-sharing site, made them publicly unavailable.
I apologize for any inconvenience this might have caused.
Remember, that this is premium content on this site and you'll need to be a "Donating Member" in order to access it (but the Resources/Knowledge Base section is worth the price of a donation, all by itself).
Hope this helps someone!
