They should just tighten until metal parts come together and meet, capturing the seals between the parts, so you stop tightening when you feel the torque go up quickly. You will find that 2 of the bolts are hard to get to the heads. The most likely thing you'll find is that the bolts are already fully tight and that you just need new seals. Replacing the seals is straightforward, but a lot of work because it requires you to take off almost everything on the left side of the engine. Once you get there, you need to have the correct seals. I know which seals originally came on your '70, but if the oil cooler and/or case has been replaced, this could make a difference. I have a text file I can send you that describes the 3 different seals and with which parts each is used. You can inspect the engine and determine which seals are needed without disassembling anything. Email me if you want a copy. Rebuilt engines with the wrong seals are relatively common. At your temps, I'd suggest 10W-40 or 15W-40 oil. In spite of what everyone else says, I'd never recommend 20W-50. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
