Whaler was the OEM manufacturer for the '85 Jetta I had, possibly this brand still is. Do not run the engine without coolant in the block (can damage the waterpump seal).
Im in the process of rebuilding my 3.0t because of a burnt exhaust valve. The engine has 210k miles and ran good up until the valve burnt up. It burned about 1 qt of oil per 1k miles and has the timing chain rattle for a second or two upon startup.

Step 1: Gain access to the intake flap. Remove the engine cover. Lift vertically from each of the four corners of the engine cover and remove the piece. Place it in a safe place.
