When I started refreshing this 16v engine it was obvious to see where the oil leaks were originating - the rear of the balance shaft housings...on both sides! As you can see from the image above - and this was after I started to clean it - the engine was caked in oily grime with fresh pools of oil behind the rear balance shaft seals. It's taken a lot of elbow grease but the engine cleaned up nice enough to begin, what I perceived to be the most arduous task - stripping off the balance shaft housings and resealing them. With all the necessary new seals ordered up, and Loctite 574 located on eBay (as this was specified by the Porsche workshop manuals I decided to hunt some done) - it was time to tackle the flanks with vigour! Not having any special Porsche tools meant I had to be a bit inventive with removing the balance shaft gears - they need to be locked in place while the bolt is removed. With those out of the way then came the dreadful looking cambelt tensioner...
